1365 * collectd: Handling of the `Include' configuration option has been
1366 fixed.
1367 * battery plugin: Don't complain about a missing directory every
1368 interval.
1369 * exec plugin: Allow executed programs to close STDERR. Thanks to
1370 Thorsten von Eicken for reporting this problem.
1371 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1372 Tomasz Pala for the patch.
1373 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1374 the patch.
1375 * memory plugin: Fix a potential problem under Solaris.
1376 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1377 to Doug MacEachern for the patch.
1379 2009-03-18, Version 4.6.2
1380 * collectd: Some Solaris utility code has been improved.
1381 * filter subsystem: Allow `Chains' without default targets.
1382 * liboping: A patch to comply with strict aliasing rules has been
1383 added.
1384 * timediff match: Fix a typo: The match was registered with a wrong
1385 name which prevented this match to be used as documented. Thanks to
1386 Bruno Prémont for finding this problem.
1387 * bind plugin: Fix collection of the cached RR sets. The number of RR
1388 sets currently in the cache was collected as a counter value, which
1389 is nonsense. Thanks to Bruno Prémont for implementing this.
1390 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1391 primarily BSDs, don't take it well and crash.
1392 * oracle plugin: Portability to 64 bit systems has been improved.
1393 * postgresql plugin: The default configuration has been improved.
1394 * rrdtool plugin: Fix a possible race condition: If the network plugin
1395 is brought and dispatches a value before the rrdtool plugin is
1396 initialized, the daemon may crash.
1398 2009-02-22, Version 4.6.1
1399 * collectd: Many documentation fixes.
1400 * Collectd::Unixsock: Error handling has been improved.
1401 * regex match: Don't link with the PCRE library.
1402 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1403 for finding and fixing most of them.
1404 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1405 faults. Thanks to Peter Holik for his patch.
1407 2009-02-16, Version 4.6.0
1408 * collectd: Added the `filter chain' infrastructure, which allows the
1409 user to use `matches' and `targets' to control value processing.
1410 * collectd: The new `-T' command line argument allows more in-depth
1411 testing of a configuration. Thanks to Doug MacEachern for the patch.
1412 * collectd-nagios: The Nagios integration command has been updated to
1413 use libcollectdclient. The `percentage' aggregation function has
1414 been added. Thanks to Fabian Linzberger for the patch.
1415 * libcollectdclient: A library which abstracts communication with the
1416 unixsock plugin for clients has been added.
1417 * regex match: Match values by their identifies using regular
1418 expressions.
1419 * timediff match: Match for values with an invalid timestamp.
1420 * value match: Select values by their data sources' values.
1421 * notification target: Create and dispatch a notification.
1422 * replace target: Replace parts of an identifier using regular
1423 expressions.
1424 * set target: Set (overwrite) entire parts of an identifier.
1425 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1426 statistics, allowing very detailed name server statistics. Thanks to
1427 Bruno Prémont for this plugin.
1428 * cpu plugin: Report `interrupt' separately when using
1429 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1430 example for native OpenBSD support, has been added. Thanks to Simon
1431 Kuhnle for the patch.
1432 * csv plugin: Make it possible to write values to STDOUT instead of
1433 files. This is meant for testing purposes mostly. The output written
1434 to STDOUT is compatible with the exec plugin. Thanks to Doug
1435 MacEachern for the patch.
1436 * curl plugin: This new plugin can be used to read web pages and parse
1437 them using the same mechanism that's used in the tail plugin.
1438 * dbi plugin: This new plugin allows you to connect to a variety of
1439 relational databases and use SQL to gather custom statistics from
1440 it. It is similar to the already existing PostgreSQL plugin but uses
1441 libdbi to communicate with the database(s).
1442 * interface plugin: Use the ignorelist framework when selecting /
1443 ignoring interfaces. This allows one to use regular expressions to
1444 select interfaces, too.
1445 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1446 Thanks to Bruno Prémont for this patch.
1447 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1448 for the patch.
1449 * mysql plugin: Allow connecting to a database via the UNIX domain
1450 socket, too. Thanks to Mirko Buffoni for the patch.
1451 * network plugin: Further performance improvements for the receive
1452 code. This hopefully will help very large setups.
1453 * openvpn plugin: This new plugin collects statistics provided by the
1454 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1455 * oracle plugin: This new plugin allows you to connect to an Oracle
1456 database and use SQL to gather custom statistics from it. It is
1457 similar to the already existing PostgreSQL plugin.
1458 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1459 have been added.
1460 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1461 * perl plugin: Added support for `notification meta data'.
1462 * perl plugin: Added support for the `filter chain' infrastructure by
1463 allowing plugins to register `matches' and `targets'.
1464 * postgresql plugin: The preferred configuration syntax has been
1465 updated to be in line with the syntax used by the new dbi and oracle
1466 plugins. The compatibility code for the old syntax is present.
1467 Support for the new `Result' blocks and the interval parameter has
1468 been added.
1469 * processes plugin: Stacksize and virtual memory usage statistics have
1470 been added. Portability fixes.
1471 * rrdcached plugin: This new plugin uses the (still in development)
1472 RRD accelerator daemon, rrdcached. This daemon works very similar to
1473 the original rrdtool plugin of collectd, but adds some more nice
1474 features.
1475 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1476 added.
1478 2009-05-09, Version 4.5.4
1479 * Build system, various plugins: Many build fixes for FreeBSD,
1480 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1481 for many fixes and providing a build system for many platforms,
1482 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1483 providing an OpenBSD system.
1484 * collectd: Fix a potential race condition when creating directories.
1485 * battery plugin: Don't complain about a missing directory every
1486 interval.
1487 * dns plugin: Slight portability fixes.
1488 * exec plugin: Allow executed programs to close STDERR. Thanks to
1489 Thorsten von Eicken for reporting this problem.
1490 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1491 Tomasz Pala for the patch.
1492 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1493 the patch.
1494 * rrdtool plugin: Fix a possible race condition: If the network plugin
1495 is initialized and dispatches a value before the rrdtool plugin is
1496 initialized, the daemon may crash.
1497 * memory plugin: Fix a potential problem under Solaris.
1499 2009-02-22, Version 4.5.3
1500 * build system: The check for libupsclient even when `pkg-config' is
1501 not available.
1502 * collectd: Fix error handling in the global cache.
1503 * Collectd::Unixsock: Error handling has been improved.
1504 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1505 patch.
1506 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1507 faults. Thanks to Peter Holik for his patch.
1508 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1509 code. Thanks to "thated" for reporting this.
1511 2009-01-02, Version 4.5.2
1512 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1513 file may be in both locations, especially when the database was
1514 installed in a non-standard path. Thanks to Dusty Doris for
1515 reporting this.
1516 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1517 Solaris, in the configure script automatically.
1518 * build system, tcpconns plugin: Check for `kvm_nlist' and
1519 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1520 library with similar functions to the BSD variant, but doesn't
1521 provide these necessary functions.
1522 * collectd.conf(5): Various fixes and clarifications.
1523 * collectd: Remove a GNUism (unnamed unions), thus improving
1524 portability.
1525 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1526 This solves portability problems, especially for Solaris.
1527 * dns plugin: Fix a portability problem with NetBSD.
1528 * filecount plugin: Fix an off-by-one error. This error may cause a
1529 segmentation fault.
1530 * network plugin: Fix the handling of `type' in the network protocol.
1531 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1532 much larger buffer. This caused the `type' to be transferred much
1533 more often than necessary. In some cases, e. g. the `cpu' and
1534 `cpufreq' plugins being used at the same time, data may be corrupted
1535 in those files. Thanks to Bruno Prémont for debugging and reporting
1536 this issue.
1537 * processes plugin: Fix a possible segmentation fault when specifying
1538 invalid configuration options.
1539 * unixsock plugin: Make sure the initialization function is run only
1540 once. This resolves a file descriptor leak under systems which run
1541 the initialization more than once, such as Solaris.
1543 2008-10-16, Version 4.5.1
1544 * build system: Change `--enable-<plugin>' to abort with an error if
1545 dependencies are not met. Thanks to Bruno Prémont for the patch.
1546 Also, the poisoning of various string functions has been restricted
1547 to debug builds.
1548 * collectd: Fix a memory leak in the global value cache. With every
1549 *missing* value a couple of bytes would be leaked. Another memory
1550 leak in the configuration handling code has been fixed. Thanks to
1551 Niraj Tolia for reporting these issues.
1552 * collectd: Fix an off-by-one error in the ignorelist functionality.
1553 When using regular expressions, the last character would be missing,
1554 possibly matching differently from what one would expect.
1555 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1556 problem.
1557 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1558 Linzberger for reporting the bug.
1559 * iptables plugin: Fix an off-by-one error. If a string was just one
1560 character too long, it was truncated instead of reporting an error.
1561 * network plugin: Fix a memory leak in the configuration handling
1562 code. Thanks to Niraj Tolia for reporting this issue.
1563 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1564 * postgresql plugin: Don't reopen connection during reinitialization.
1565 This fixes a bug under Solaris and potentially other platforms.
1566 Missing calls to `PQclear' have been added, too. This fixes memory
1567 leaks. Thanks to ``Admin'' for reporting these bugs.
1568 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1569 library.
1570 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1571 problems with some `libc's. Thanks to Matthias Lay for reporting the
1572 bug.
1574 2008-09-04, Version 4.5.0
1575 * collectd: Added the ability to flush certain identifiers.
1576 * collectd: The concept of `notification meta data' has been
1577 introduced.
1578 * filecount plugin: The new filecount plugin counts the number of
1579 files in a directory and its subdirectories.
1580 * ipmi plugin: Sensor names have been changed to ensure unique names.
1581 Notifications upon added and removed sensors can now be generated.
1582 * notify_desktop plugin: This new plugin sends notifications to the
1583 X desktop using the structure defined in the `Desktop Notification
1584 Specification'.
1585 * notify_email plugin: This new plugin sends out notifications via
1586 email, using the `esmtp' library.
1587 * onewire plugin: The new experimental(!) onewire plugin reads values,
1588 such as temperatures, from sensors connected to the computer via the
1589 onewire bus.
1590 * perl plugin: Improved synchronized access to internal data structures
1591 and fixed a possible dead-lock.
1592 * perl plugin: Added the ability to flush certain identifiers and marked
1593 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1594 plugin_flush().
1595 * perl plugin: Added the ability to configure Perl plugins.
1596 * postgresql plugin: The new postgresql plugin collects statistics
1597 about or from a PostgreSQL database.
1598 * processes plugin: The `ProcessMatch' option has been added.
1599 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1600 IO load.
1601 * tcpconns plugin: This plugin has been ported to OpenBSD.
1602 * thermal plugin: The new thermal plugin collects system temperatures
1603 using Linux ACPI thermal zone data.
1605 2009-01-02, Version 4.4.5
1606 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1607 file may be in both locations, especially when the database was
1608 installed in a non-standard path. Thanks to Dusty Doris for
1609 reporting this.
1610 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1611 Solaris, in the configure script automatically.
1612 * collectd.conf(5): Various fixes and clarifications.
1613 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1614 portability problems, especially for Solaris.
1615 * dns plugin: Fix a portability problem with NetBSD.
1616 * network plugin: Fix the handling of `type' in the network protocol.
1617 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1618 much larger buffer. This caused the `type' to be transferred much
1619 more often than necessary. In some cases, e. g. the `cpu' and
1620 `cpufreq' plugins being used at the same time, data may be corrupted
1621 in those files. Thanks to Bruno Prémont for debugging and reporting
1622 this issue.
1623 * unixsock plugin: Make sure the initialization function is run only
1624 once. This resolves a file descriptor leak under systems which run
1625 the initialization more than once, such as Solaris.
1627 2008-10-16, Version 4.4.4
1628 * build system: Change `--enable-<plugin>' to abort with an error if
1629 dependencies are not met. Thanks to Bruno Prémont for the patch.
1630 Also, the poisoning of various string functions has been restricted
1631 to debug builds.
1632 * collectd: Fix a memory leak in the global value cache. With every
1633 *missing* value a couple of bytes would be leaked. Another memory
1634 leak in the configuration handling code has been fixed. Thanks to
1635 Niraj Tolia for reporting these issues.
1636 * collectd: Fix an off-by-one error in the ignorelist functionality.
1637 When using regular expressions, the last character would be missing,
1638 possibly matching differently from what one would expect.
1639 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1640 problem.
1641 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1642 Linzberger for reporting the bug.
1643 * network plugin: Fix a memory leak in the configuration handling
1644 code. Thanks to Niraj Tolia for reporting this issue.
1645 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1646 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1647 problems with some `libc's. Thanks to Matthias Lay for reporting the
1648 bug.
1650 2008-09-01, Version 4.4.3
1651 * collectd: Fix a memory leak in the threshold checking code.
1652 * memcached plugin: Fix a too short timeout and a related file
1653 descriptor leak.
1654 * memory plugin: A typo in the libstatgrab code has been fixed.
1655 * snmp plugin: Fix a possible memory leak.
1657 2008-07-15, Version 4.4.2
1658 * build system: Use pkg-config to detect the upsclient library.
1659 * collectd: Try even harder to determine the endianness of the
1660 architecture collectd is being built on.
1661 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1662 of disks.
1663 * dns plugin: Fix compilation errors with BIND versions 19991001
1664 through 19991005.
1665 * network plugin: Bugfix in the init routine: The init function
1666 cleared a buffer regardless of its contents. This could lead to lost
1667 values under Solaris.
1668 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1669 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1670 function.
1671 * wireless plugin: Work around incorrect noise and power values
1672 returned by some broken drivers.
1674 2008-06-03, Version 4.4.1
1675 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1676 to kyrone for reporting this.
1677 * collectd: Fixed min/max output in notifications generated by
1678 threshold checking.
1679 * collectd-nagios: Fix the protocol used to communicate with the
1680 daemon.
1681 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1682 initialization has errors. An issue with Perl 5.10 has been fixed.
1683 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1684 René Rebe and Siegmund Gorr for reporting this.
1686 2008-05-06, Version 4.4.0
1687 * collectd: Internal code cleanups.
1688 * collectd: Added support for a `Flush' command in the unixsock and
1689 exec plugins. This command can be used to force a plugin (or all) to
1690 flush its values to disk.
1691 * collectd: Thresholds can now be configured to apply to one data
1692 source only, making it possible to configure different thresholds
1693 for each data source.
1694 * apache, nginx plugins: Added the possibility to disable host and/or
1695 peer verification.
1696 * ascent plugin: The new ascent plugin reads and parses the statistics
1697 page of an Ascent server.
1698 * cpu plugin: Support for the statgrab library has been added.
1699 * disk plugin: The possibility to ignore certain disks or collect only
1700 specific disks has been added.
1701 * disk plugin: Support for the statgrab library has been added.
1702 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1703 sensor values via IPMI, the intelligent platform management
1704 interface.
1705 * iptables plugin: The iptc library that is used by the iptables
1706 plugin has been added to the distribution, because it is not
1707 provided by all distributions and removed from at least one.
1708 * powerdns plugin: The new powerdns plugin reads statistics from an
1709 authoritative or a recursing PowerDNS name server.
1710 * rrdtool plugin: The size of the files generated with the default
1711 configuration has been decreased.
1712 * tail plugin: The new tail plugin can be used to gather statistics by
1713 continuously reading from log files.

1715 TeamSpeak2 server and collects statistics about the number of users
1716 and number of channels.
1717 * users plugin: Support for the statgrab library has been added.
1718 * vmem plugin: The new vmem plugin collects very detailed statistics
1719 about the virtual memory subsystem of Linux.
1721 2008-08-30, Version 4.3.4
1722 * Build system: Improved detection of and linking with the statgrab
1723 library.
1724 * collectd: Portability fixes, especially to determine endianness more
1725 reliable.
1726 * Various plugins: Fix format strings.
1727 * disk plugin: A fix for giving disks under Linux 2.4 the right names

1740 * build system: Improved detection of several libraries, especially if
1741 they are in non-standard paths.
1742 * build system: Portability fixes: Automatically define "_REENTRANT"
1743 if the libc expects it.
1744 * collectd: Error and warning messages have been improved.
1745 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1746 using them.
1747 * apache plugin: Allocate new memory when reading a webpage instead of
1748 using a buffer of static size.
1749 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1750 the program.
1751 * hddtemp plugin: Error and warning messages have been improved.
1752 * sensors plugin: Fix sensor collection for some chip types.
1754 2008-03-29, Version 4.3.2
1755 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1756 `Persist' threshold options.
1757 * collectd: Fix handling of missing values in the global value cache.
1758 * collectd: Improved error messages when parsing the configuration.
1759 * sensors plugin: Fix temperature collection with libsensors4.
1760 * unixsock plugin: Fix mixed input and output operation on streams.
1761 * wireless plugin: Fix reading noise value.
1763 2008-03-05, Version 4.3.1
1764 * exec plugin: Set supplementary group IDs.
1765 * network plugin:
1766 + Use `memcpy' when constructing/parsing a package to avoid
1767 alignment problems on weird architectures, such as Sparc.
1768 + Translate doubles to/from the x86 byte representation to ensure
1769 cross-platform compatibility.
1770 * ping plugin: Correct the handling of the `TTL' setting.
1771 * swap plugin: Reapply a patch for Solaris.
1772 * tcpconns plugin: Portability improvements.
1774 2008-02-18, Version 4.3.0
1775 * collectd: Notifications have been added to the daemon. Notifications
1776 are status messages that may be associated with a data instance.
1777 * collectd: Threshold checking has been added to the daemon. This
1778 means that you can configure threshold values for each data
1779 instance. If this threshold is exceeded a notification will be
1780 created.
1781 * collectd: The new `FQDNLookup' option tells the daemon to use the
1782 full qualified domain name as the hostname, not just the host part
1783 es returned by `gethostname(2)'.
1784 * collectd: Support for more than one `TypesDB' file has been added.
1785 This is useful when one such file is included in a package but one
1786 wants to add custom type definitions.
1787 * collectd: The `Include' config option has been expanded to handle
1788 entire directories and shell wildcards.
1789 * collectdmon: The new `collectdmon' binary detects when collectd
1790 terminates and automatically restarts it again.
1791 * csv plugin: The CSV plugin is now able to store counter values as a
1792 rate, using the `StoreRates' configuration option.
1793 * exec plugin: Handling of notifications has been added and the
1794 ability to pass arguments to the executed programs has been added.
1795 * hddtemp plugin: The new `TranslateDevicename' option lets you
1796 disable the translation from device names to major-minor-numbers.
1797 * logfile plugin: Handling of notifications has been added.
1798 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1799 domain name lookups in this plugin.
1800 * perl plugin: Many internal changes added support for handling multiple
1801 threads making the plugin reasonably usable inside collectd. The API has
1802 been extended to support notifications and export global variables to
1803 Perl plugins; callbacks now have to be identified by name rather than a
1804 pointer to a subroutine. The plugin is no longer experimental.
1805 * uuid plugin: The new UUID plugin sets the hostname to an unique
1806 identifier for this host. This is meant for setups where each client
1807 may migrate to another physical host, possibly going through one or
1808 more name changes in the process. Thanks to Richard Jones from
1809 Red Hat's Emerging Technology group for this plugin.
1810 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1811 CPU, disk and network statistics about guest systems on the same
1812 physical server. Thanks to Richard Jones from Red Hat's Emerging
1813 Technology group for this plugin.
1815 2008-04-22, Version 4.2.7
1816 * build system: Improved detection of several libraries, especially if
1817 they are in non-standard paths.
1818 * build system: Portability fixes: Automatically define "_REENTRANT"
1819 if the libc expects it.
1820 * collectd: Error and warning messages have been improved.
1821 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1822 using them.
1823 * apache plugin: Allocate new memory when reading a webpage instead of
1824 using a buffer of static size.
1825 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1826 the program.
1827 * hddtemp plugin: Error and warning messages have been improved.
1828 * sensors plugin: Fix sensor collection for some chip types.
1830 2008-03-29, Version 4.2.6
1831 * collectd: Improved error messages when parsing the configuration.

1833 * unixsock plugin: Fix mixed input and output operation on streams.
1834 * wireless plugin: Fix reading noise value.
1836 2008-03-04, Version 4.2.5
1837 * apache plugin: Improved initialization and error messages.
1838 * exec plugin: Set supplementary group IDs.
1839 * network plugin:
1840 + Create separate threads for reading from the socket and parsing
1841 and dispatching incoming packets. Versions prior to this may have
1842 problems in high-load situations, where the socket receive buffers
1843 overflows, resulting in gaps in the data.
1844 + Use `memcpy' when constructing/parsing a package to avoid
1845 alignment problems on weird architectures, such as Sparc.
1846 + Translate doubles to/from the x86 byte representation to ensure
1847 cross-platform compatibility.
1848 * ping plugin: Correct the handling of the `TTL' setting.
1849 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1850 * swap plugin: Reapply a patch for Solaris.
1851 * tcpconns plugin: Portability improvements.
1853 2008-01-21, Version 4.2.4
1854 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1855 the permission on the socket as documented in the manpage. Thanks to
1856 Evgeny Chukreev for fixing this issue.
1857 * collectd: The documentation has been improved.
1859 2007-12-28, Version 4.2.3
1860 * sensors plugin: Updated the plugin to build and work with version 3
1861 of the libsensors library.
1863 2007-12-15, Version 4.2.2
1864 * nginx plugin: Incorrect comparison of strings lead to a segfault
1865 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1866 this.
1867 * logfile plugin: The config option `Timestamp' was handled
1868 incorrectly and basically always active. Thanks to Luke Heberling
1869 for fixing this.
1871 2007-11-08, Version 4.2.1
1872 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1873 enabled on the host.
1874 * snmp plugin: Fix a memory leak.
1876 2007-10-27, Version 4.2.0
1877 * collectd: The new config option `Include' lets you include other
1878 configfiles and thus split up your config into smaller parts. This
1879 may be especially interesting for the snmp plugin to keep the data
1880 definitions separate from the host definitions.
1881 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1882 (number of connections, octets and packets for each service and
1883 destination). Thanks to Sebastian Harl for this plugin.
1884 * memcached plugin: The new `memcached' plugin connects to a memcached
1885 daemon process and collects statistics of this distributed caching
1886 system. Thanks to Antony Dovgal for contributing this plugin.
1887 * nginx plugin: The new `nginx' plugin reads the status page of an
1888 nginx daemon and saves the handled connections and requests.
1889 * perl plugin: Many changes, including the added `EnableDebugger'
1890 config option which lets you debug your Perl plugins more easily.
1891 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1892 be more thread-safe otherwise by locking calls to the library.
1893 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1894 correct the values returned by SNMP-agents. If a <data> block is
1895 defined as `table' the instance is now optional. The sequence number
1896 is used as the type-instance in this case. The new `InstancePrefix'
1897 option allows to add arbitrary prefixes to the type-instance.
1898 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1899 certain TCP connections and what state they're in. This can be used
1900 to see how many connections your FTP server has to handle or how
1901 many outgoing connections your mailserver has open.
1903 2008-01-11, Version 4.1.6
1904 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1905 the permission on the socket as documented in the manpage. Thanks to
1906 Evgeny Chukreev for fixing this issue.
1907 * collectd: The documentation has been improved.
1909 2007-12-27, Version 4.1.5
1910 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1911 memory situations.
1912 * sensors plugin: Updated the plugin to build and work with version 3
1913 of the libsensors library.
1915 2007-11-08, Version 4.1.4
1916 * Build system: Improve detection of the rrd library, especially if
1917 it's in a non-standard location.
1918 * Build system: A bug when parsing the argument for
1919 `--with-libnetsnmp' has been fixed.
1920 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1921 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1922 a deadlock or delay when shutting down the daemon.
1923 * snmp plugin: Fix a memory leak.
1925 2007-10-24, Version 4.1.3
1926 * collectd: A build issue under Solaris has been resolved by renaming
1927 data types.
1928 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1929 be more thread-safe otherwise by locking calls to the library.
1931 2007-09-28, Version 4.1.2
1932 * apcups plugin: Fix reporting of the `load percent' data.
1933 * wireless plugin: Correct the handling of cards returning signal and
1934 noise quality as percentage.
1935 * perl plugin: Fix a possible buffer overflow in get_module_name().
1936 * build system: Further improve the detection of libraries.
1937 * netlink plugin: Build issues under some older versions of the Linux
1938 includes (i. e. Debian Sarge) have been fixed.
1939 * snmp plugin: Fix a potential segfault when a host times out. Add
1940 support for the `timeticks' type.
1942 2007-09-12, Version 4.1.1
1943 * Build system: The detection of `libnetlink' has been improved.
1944 * collectd: The documentation has been fixed in numerous places.
1945 * exec plugin: Setting the group under which to run a program has been
1946 fixed.
1947 * collectd: The `sstrerror' function was improved to work correctly
1948 with the broken GNU version of `strerror_r'.
1949 * collectd: Write an error message to STDERR when loading of a plugin
1950 fails.
1951 * apcups plugin: Fix the `types' used to submit the values: They still
1952 has an `apcups_' prefix which doesn't work anymore.
1953 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1954 whatever the client thinks is `now'..
1956 2007-09-01, Version 4.1.0
1957 * Build system: The build system has been changed to automatically
1958 disable all plugins, which are missing dependencies. The dependency
1959 checking has been removed from the plugins themselves to remove
1960 redundancy.
1961 * Flexible interval: The interval of collected data is now sent along
1962 with the data itself over the network, so that the interval-settings
1963 of server and clients no longer needs to match.
1964 * netlink plugin: The new `netlink' plugin connects to the Linux
1965 kernel using a netlink socket and uses it to query information about
1966 interfaces, qdiscs and classes.
1967 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1968 to not block data collection.
1969 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1970 network devices, such as switches, routers, thermometers, rack
1971 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1972 plugin.
1973 * unixsock plugin: Added the `LISTVAL' command.
1974 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1975 of music played with xmms.
1977 2007-09-28, Version 4.0.9
1978 * apcups plugin: Fix reporting of the `load percent' data.
1979 * wireless plugin: Correct the handling of cards returning signal and
1980 noise quality as percentage.
1981 * perl plugin: Fix a possible buffer overflow in get_module_name().
1983 2007-09-12, Version 4.0.8
1984 * collectd: The `sstrerror' function was improved to work correctly
1985 with the broken GNU version of `strerror_r'.
1986 * collectd: Write an error message to STDERR when loading of a plugin
1987 fails.
1988 * apcups plugin: Fix the `types' used to submit the values: They still
1989 has an `apcups_' prefix which doesn't work anymore.
1990 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1991 whatever the client thinks is `now'..
1993 2007-08-26, Version 4.0.7
1994 * documentation: Some typos have been fixed and some information has
1995 been improved.
1996 * build system: Many fixes for detecting libraries in unusual places,
1997 such as on RedHat systems. The affected libraries are `libcurl',
1998 `libmysql', and `libupsclient'.
1999 * network plugin: Allow the `Port' option to be specified as a number
2000 (i. e. without quotes).
2001 * nut plugin: A fix allows linking the nut plugin against
2002 libupsclient, version >= 2.2.0.
2003 * processes plugin: Fix a potential segmentation fault.
2005 2007-07-30, Version 4.0.6
2006 * sensors plugin: Fix the ignorelist functionality: Only the `type
2007 instance' was used to match against the list, but the documentation
2008 told otherwise. This release fixes the code, so it complies with the
2009 documentation.
2010 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2011 configuration messages will end up in the logging facility.
2012 * conrtib/fedora: The contributed specfile for Fedora has been
2013 updated.
2015 2007-07-05, Version 4.0.5
2016 * Portability: More fixes for OpenBSD have been included.
2018 2007-06-24, Version 4.0.4
2019 * cpu plugin: Fixed the Solaris code.
2020 * dns plugin: Fixed a build issue for OpenBSD.
2021 * interface plugin: Fixed the Solaris code.
2022 * load plugin: Fixed the alternative `/proc' Linux code.
2023 * memory plugin: Fixed the Solaris code.
2024 * oconfig: Don't require `-lfl' anymore.
2026 2007-06-19, Version 4.0.3
2027 * cpu plugin: Fix the Darwin / Mac OS X code.
2028 * ping plugin: Use the return value of `getpid', not its address.
2029 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2030 initialized correctly.
2031 * configure: Added `--with-nan-emulation' to aid cross compilation.
2033 2007-06-12, Version 4.0.2
2034 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2035 they're given in numerically form.
2037 2007-06-07, Version 4.0.1
2038 * iptables plugin: A bug in the configuration routine has been fixed.
2039 Setting a comment in the configfile will no longer cause a
2040 segmentation fault.
2042 2007-06-03, Version 4.0.0
2043 * collectd: The plugin-infrastructure has been changed to allow for
2044 more types of plugins, namely `write' and `log' plugins.
2045 * collectd: The read-function has been changed to read many plugins in
2046 parallel, using threads. Thus, plugins generally need to use
2047 thread-safe functions from now on.
2048 * collectd: The '-t' command line options allows to perform syntax tests
2049 of the configuration file and exit immediately.
2050 * csv plugin: The new `csv' plugin handles output to `comma separated
2051 values'-files.
2052 * rrdtool plugin: The new `rrdtool' plugin handles output to
2053 RRD-files. Data can be cached to combine multiple updates into one
2054 write to increase IO-performance.
2055 * network plugin: The new `network' plugin handles IO via the network.
2056 It implements a different, much more extensible protocol which can
2057 combine many values in one packet, decreasing the number of UDP-
2058 packets being sent. It can read from and send to the network and
2059 with the appropriate configuration even forward packets to other
2060 networks.
2061 * unixsock plugin: The new `unixsock' plugin provides an interface to
2062 communicate with the daemon while it is running. Right now the
2063 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2064 come.
2065 * perl plugin: The new `perl' plugin allows you to write extensions
2066 for collectd in the scripting-language Perl.
2067 * logfile plugin: The new `logfile' plugin writes logmessages to files
2068 or STDOUT or STDERR.
2069 * syslog plugin: The new `syslog' plugin sends logmessages to the
2070 system's syslog daemon.
2071 * entropy plugin: The new `entropy' plugin collects the amount of
2072 entropy currently being available to the system.
2073 * exec plugin: The new `exec' plugin forks child processes and reads
2074 back values provided by the forked processes.
2075 * iptables plugin: The new `iptables' plugin reads counters from
2076 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2077 plugin.
2078 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2079 to Peter Holik for contributing this plugin.
2080 * nut plugin: The new `nut' plugin connects the upsd of the `network
2081 ups tools' and reads information about the connected UPS.
2082 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2083 connections) field was added by Florent Monbillard.
2084 * collectd-nagios: The new `collectd-nagios' binary queries values
2085 from collectd, parses them and exits according to Nagios-standards.
2086 * manpages: The manpages have been improved a lot.
2088 2007-09-28, Version 3.11.7
2089 * wireless plugin: Correct the handling of cards returning signal and
2090 noise quality as percentage.
2092 2007-08-31, Version 3.11.6
2093 * processes plugin: Fix a potential segmentation fault.
2095 2007-05-29, Version 3.11.5
2096 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2097 * ntpd plugin: Fix a potential buffer overflow.
2098 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2099 were accounted as `zombies'.
2101 2007-04-10, Version 3.11.4
2102 * dns plugin: Change the order of includes to make the plugin compile
2103 under FreeBSD.
2105 2007-03-30, Version 3.11.3
2106 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2107 of the unused `COLLECT_KSTAT'.
2109 2007-02-11, Version 3.11.2
2110 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2111 NULL-pointer may have been passed to `printf' which causes a
2112 segfault with some libcs.
2114 2007-02-10, Version 3.11.1
2115 * df plugin: Some wrong defines have been fixed so the plugin works
2116 under Solaris again.
2117 * dns plugin: The usage of a struct has been fixed to work with
2118 non-GNU libcs.
2119 * processes plugin: Some missing defines have been added so the plugin
2120 compiles cleanly under FreeBSD and presumably other UNIXes.
2122 2006-12-22, Version 3.11.0
2123 * collectd: The new command line option `-P' makes it easier for
2124 distributors to change the location of PID-files.
2125 * collectd: The daemon shuts down faster now which makes it easier to
2126 write init.d-scripts for it.
2127 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2128 caused problems every now and then.
2129 * df plugin: New config options allow to ignore certain mountpoints,
2130 filesystem types or devices.
2131 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2132 and interprets it. It collects traffic as well as qtype, opcode and
2133 rcode counts.
2134 * email plugin: Sebastian Harl has contributed this plugin which
2135 counts received mails in categories (e. g. ham, spam, virus), spam
2136 score (as given by SpamAssassin) and check types.
2137 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2138 uses `mbmon' to gather information from sensors on the motherboard.
2139 * processes plugin: Collect detailed statistics for configured
2140 processes, that's process and thread count, CPU usage, resident
2141 segment size and pagefaults.
2142 * multimeter plugin: Peter Holik contributed a new plugin which
2143 queries multimeters.
2144 * sensors plugin: Lubos Stanek has put much effort into improving this
2145 plugin, including `extended naming', collection of voltage values
2146 and the possibility to ignore certain values.
2148 2006-12-21, Version 3.10.4
2149 * Max Kellermann has identified a bug in the server routine: When
2150 opening a socket fails the daemon will (re)try opening the socket in
2151 an endless loop, ultimately leading to a `EMFILE' error.
2153 2006-11-04, Version 3.10.3
2154 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2155 ntpd's reply was sent in more than one packet, the buffer size was
2156 calculated incorrectly, resulting in the reading of uninitialized or
2157 freed memory.
2159 2006-11-01, Version 3.10.2
2160 * The sample config file has been improved.
2161 * Errors in the manpages have been corrected.
2162 * The ping-plugin now adds hosts during initialization, not during
2163 startup. This speeds up startup when no network connectivity is
2164 available. Also, the hosts are being added later when the network is
2165 available.
2166 * Improved BSD-support for the df-plugin.
2167 * Fixed syntax errors in the swap-plugin for Mac OS X.
2168 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2169 plugin.
2170 * Don't disable the mysql-plugin if connecting to the database fails
2171 during initialization. Instead, try again in increasing intervals.
2173 2006-07-19, Version 3.10.1
2174 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2175 the apcups cannot be reached, unconnected sockets will pile up and
2176 eventually lead to `Too many open files' errors.
2178 2006-07-09, Version 3.10.0
2179 * The `disk' plugin has been ported to Darwin.
2180 * The `battery' plugin should work on many Apple computers now.
2181 * The `traffic' plugin can now ignore certain interfaces. Also,
2182 statistics for sent/received packets and errors have been added.
2183 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2184 to Anthony Gialluca for contributing this plugin and providing me
2185 with a test environment :)
2186 * A plugin for monitoring an NTP instance and the local clock drift
2187 has been added.
2189 2006-06-25, Version 3.9.4
2190 * The Solaris code in the `swap' plugin has been changed to reflect
2191 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2192 working this out.
2193 * The debugging system has been fixed to work with the Sun libc.
2194 * When built without librrd the variable `operating_mode' could be
2195 uninitialized. Thanks to David Elliot for reporting the bug.
2197 2006-06-01, Version 3.9.3
2198 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2199 operating systems also profit from the changes, but I wasn't able to
2200 check that.
2201 * Changed the build system to find the netinet-includes under FreeBSD
2202 and therefore successfully build the `liboping' library there.
2204 2006-05-09, Version 3.9.2
2205 * Applied a patch to the `liboping' library. Due to a bug in the
2206 sequence checking the `ping' plugin stopped working after
2207 approximately 7.6 days.
2209 2006-05-09, Version 3.8.5
2210 * Applied a patch to the `liboping' library. Due to a bug in the
2211 sequence checking the `ping' plugin stopped working after
2212 approximately 7.6 days.
2214 2006-04-21, Version 3.9.1
2215 * Build issues with Solaris and possible other architectures have been
2216 resolved.
2217 * Problems when building the `apache'-plugin without `libcurl' have
2218 been resolved.
2219 * A bug in the `ping' plugin has been fixed. Sorry folks.
2221 2006-04-02, Version 3.9.0
2222 * A plugin to monitor the Apache webserver has been added.
2223 <http://httpd.apache.org/>
2224 * A plugin to collect statistics about virtual servers using VServer.
2225 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2226 this plugin :)
2227 * A plugin for wireless LAN cards has been added. It monitors signal
2228 strength, link quality and noise ratio..
2229 * A plugin for Apple hardware sensors has been added.
2230 * An option to compile collectd with different `step' and `heartbeat'
2231 settings has been added. The size of RRAs is no longer static but
2232 calculated based on the settings for `step' and `width'.
2233 * The `ping' plugin can now be configured to use a certain TTL.
2234 * A plugin to monitor the hardware sensors of Apple computers has been
2235 added.
2236 * The plugins `cpu', `memory', `processes' and `traffic' have been
2237 ported to Mach/Darwin (Mac OS X).
2238 * The `log mode' has been contributed by Christophe Kalt. It writes
2239 the data into text files rather than RRD files.
2241 2006-04-09, Version 3.8.4
2242 * Applied patch by Vincent Stehlé which improves the disk-name
2243 resolution in the `hddtemp' plugin for Linux systems.
2245 2006-04-02, Version 3.8.3
2246 * Applied a patch by James Byers: The MySQL plugin was not working
2247 with MySQL 5.0.2 or later.
2249 2006-03-14, Version 3.8.2
2250 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2251 the GNU libc, because it points to `/etc/fstab' rather than
2252 `/etc/mtab'.
2254 2006-03-13, Version 3.8.1
2255 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2256 * Fixes in the debian `postinst' and `init.d' scripts.
2258 2006-03-09, Version 3.8.0
2259 * The `ping' plugin no longer uses `libping' but a self written
2260 library named `liboping'. With this library it's possible to ping
2261 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2263 2006-02-18, Version 3.7.2
2264 * A simple bug in the `battery' plugin has been fixed. It should now
2265 work with ACPI based batteries as well. Thanks to Sebastian for
2266 fixing this.
2267 * Fixing a bug that prevented collectd to be built without librrd.
2268 Thanks to Werner Heuser for reporting it.
2270 2006-02-04, Version 3.7.1
2271 * The new network code has been improved to build with older versions
2272 of glibc.
2273 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2274 to Tommie Gannert for this patch.
2276 2006-01-30, Version 3.7.0
2277 * The `battery' plugin has been added. It collects information about
2278 laptop batteries..
2279 * The MySQL plugin has been improved: It now writes two more RRD
2280 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2281 * The `cpufreq' plugin now reads another file since the file it did
2282 read so far causes much overhead in the kernel. Also, you need root
2283 to read the old file, but not to read the new one.
2284 * The `hddtemp' plugin can now be configured to connect to another
2285 address and/or port than localhost.
2286 * The `df' plugin now prefers `statvfs' over `statfs'.
2287 * The network code has been rewritten. collectd now supports unicast
2288 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2289 be set in the configfile.
2291 2006-01-24, Version 3.6.2
2292 * Due to a bug in the configfile handling collectd wouldn't start in
2293 client mode. This released fixes this.
2295 2006-01-20, Version 3.6.1
2296 * Due to a bug in `configure.in' all modules and the binary were
2297 linked against `libmysqlclient'. This issue is solved by this
2298 release.
2300 2006-01-17, Version 3.6.0
2301 * A config file has been added. This allows for loading only specific
2302 plugins.
2303 * A `df' plugin has been added.
2304 * A `mysql' plugin has been added.
2305 * The `ping' plugin doesn't entirely give up hope when a socket error
2306 occurred, but will back of and increase the intervals between tries.
2308 2006-01-21, Version 3.5.2
2309 * Fixed yet another bug in the signal handling.. Stupid typo..
2310 * Improved the ping plugin to not give up on socket errors (backport
2311 from 3.6.0).
2313 2005-12-18, Version 3.5.1
2314 * The PID-file is now deleted correctly when shutting down the daemon.
2315 * SIGINT and SIGTERM are now handled correctly.
2317 2005-12-16, Version 3.5.0 (Revision 326)
2318 * A bug in the `load' module under Solaris has been fixed.
2319 * The `users' module has been contributed by Sebastian Harl. It counts
2320 currently logged in users.
2321 * The CPU module now works under FreeBSD without the use of
2322 `libstatgrab', however SMP support is missing.
2323 * The default directories for the RRD files and the PID file now
2324 depend on the compile time setting of `localstatedir'.
2326 2005-11-15, Version 3.4.0 (Revision 236)
2327 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2328 from gentoo's bugzilla for writing the patch.
2329 * The build dependency for librrd has been removed. Binaries built
2330 without librrd are client-only and will multicast their value as
2331 with the `-c' argument.
2332 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2333 * The newly introduced `-f' switch prevents daemon initialization
2334 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2335 Barcellos for this patch.
2337 2005-11-04, Version 3.3.0 (Revision 216)
2338 * New modules have been added:
2339 - `serial', for monitoring traffic on the serial interfaces
2340 - `nfs', for graphing NFS procedure calls
2341 - `tape', traffic from/to tape devices
2342 * The memory.rrd now accepts more than 4Gig of memory.
2344 2005-10-26, Version 3.2.0 (Revision 200)
2345 * Support for graphing the processes has been added (thanks to Lyonel
2346 Vincent)
2347 * If reading from hddtemp fails collectd will increase the time
2348 between polls up to one day.
2349 * The init.d files have been improved.
2350 * Problems with the spec file have been fixed.
2352 2005-10-16, Version 3.1.0 (Revision 194)
2353 * Added the `setsid' syscall to the startup code.
2354 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2356 2005-09-30, Version 3.0.0 (Revision 184)
2357 * The ability to send/receive data to/from the network (think
2358 multicast) has been added.
2359 * Modules have been split up into shared libraries can be loaded at
2360 runtime. The biggest advantage is that the core program doesn't need
2361 to be linked against an external library.
2362 * A patch by George Kargiotakis has been applied: It fixes the sensors
2363 behaviour then more than one sensor is being queried.
2365 2005-09-16, Version 2.1.0 (Revision 172)
2366 * A module for swap statistics has been added.
2368 2005-09-09, Version 2.0.0 (Revision 135)
2369 * Filenames can no longer be configured at program startup. The only
2370 options as of this version are the directory and ping hosts.
2371 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2372 Soft-IRQ statistics are added to `System'.
2373 * Diskstats now collect read and write bytes, not sectors.
2374 * Ping statistics can now be collected for more than one host. There
2375 is no default any more: If no host is given no host will be pinged.
2376 * A self-written patch for libping has been applied so it builds
2377 cleanly.
2379 2005-09-01, Version 1.8.1 (Revision 123)
2380 * Much improved configure-script: libraries and features may now be
2381 disabled.
2382 * More detailed warnings/error messages when RRD update fails.
2384 2005-08-29, Version 1.8.0:
2385 * Support for collecting disk statistics under Solaris.
2387 2005-08-25, Version 1.7.0:
2388 * Support for libstatgrab[1] for load, memory usage and network
2389 traffic. CPU- and disk-usage are not (yet) supported, since
2390 libstatgrab returns insufficient information. I will contact the
2391 authors.
2392 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2393 aren't necessarily counted linear which is now handled correctly.
2394 [1]: http://www.i-scream.org/libstatgrab/
2396 2005-08-21, Version 1.6.0:
2397 * Basic support for Solaris: System load and cpu-usage can be
2398 collected under Solaris, too. Other stats will follow later.
2399 * Many fixes in the autoconf-script
2400 * Collection/Museum scripts have been added under contrib/museum
2401 * collectd may now be started in unprivileged mode, though ping
2402 statistics will not work.
2404 2005-07-17, Version 1.5.1:
2405 * Diskstats-RRDs now use major/minor for naming. Some systems have
2406 weird strings as disk-names..
2408 2005-07-17, Version 1.5:
2409 * A new module, diskstats, has been added. It collects information
2410 about the disks and partitions.
2412 2005-07-11, Version 1.4.2:
2413 * The meminfo module has been changed to work with more platforms
2414 and/or kernel versions.
2416 2005-07-10, Version 1.4.1: Correct traffic stats
2417 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2418 forgot to correct when I changed that module.
2420 2005-07-09, Version 1.4: More traffic stats
2421 * Traffic is now collected for all interfaces that can be found
2422 * Temperature-statistics are read from lm-sensors if available
2424 2005-07-08, Version 1.3: CPU stats
2425 * Collecting CPU statistics now
2427 2005-07-12, Version 1.2: Using syslog
2428 * collectd is now using the syslog facility to report errors, warnings
2429 and the like..
2430 * The default directory is now /var/db/collectd
2432 2005-07-10, Version 1.1: Minor changes
2433 * Nothing really useful to say ;)
2435 2005-07-09, Version 1.0: Initial Version
2436 * The following modules are provided:
2437 * Load average
2438 * Ping time
2439 * Traffic
2440 * Memory info
