1367 primarily BSDs, don't take it well and crash.
1368 * oracle plugin: Portability to 64 bit systems has been improved.
1369 * postgresql plugin: The default configuration has been improved.
1370 * rrdtool plugin: Fix a possible race condition: If the network plugin
1371 is brought and dispatches a value before the rrdtool plugin is
1372 initialized, the daemon may crash.
1374 2009-02-22, Version 4.6.1
1375 * collectd: Many documentation fixes.
1376 * Collectd::Unixsock: Error handling has been improved.
1377 * regex match: Don't link with the PCRE library.
1378 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1379 for finding and fixing most of them.
1380 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1381 faults. Thanks to Peter Holik for his patch.
1383 2009-02-16, Version 4.6.0
1384 * collectd: Added the `filter chain' infrastructure, which allows the
1385 user to use `matches' and `targets' to control value processing.
1386 * collectd: The new `-T' command line argument allows more in-depth
1387 testing of a configuration. Thanks to Doug MacEachern for the patch.
1388 * collectd-nagios: The Nagios integration command has been updated to
1389 use libcollectdclient. The `percentage' aggregation function has
1390 been added. Thanks to Fabian Linzberger for the patch.
1391 * libcollectdclient: A library which abstracts communication with the
1392 unixsock plugin for clients has been added.
1393 * regex match: Match values by their identifies using regular
1394 expressions.
1395 * timediff match: Match for values with an invalid timestamp.
1396 * value match: Select values by their data sources' values.
1397 * notification target: Create and dispatch a notification.
1398 * replace target: Replace parts of an identifier using regular
1399 expressions.
1400 * set target: Set (overwrite) entire parts of an identifier.
1401 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1402 statistics, allowing very detailed name server statistics. Thanks to
1403 Bruno Prémont for this plugin.
1404 * cpu plugin: Report `interrupt' separately when using
1405 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1406 example for native OpenBSD support, has been added. Thanks to Simon
1407 Kuhnle for the patch.
1408 * csv plugin: Make it possible to write values to STDOUT instead of
1409 files. This is meant for testing purposes mostly. The output written
1410 to STDOUT is compatible with the exec plugin. Thanks to Doug
1411 MacEachern for the patch.
1412 * curl plugin: This new plugin can be used to read web pages and parse
1413 them using the same mechanism that's used in the tail plugin.
1414 * dbi plugin: This new plugin allows you to connect to a variety of
1415 relational databases and use SQL to gather custom statistics from
1416 it. It is similar to the already existing PostgreSQL plugin but uses
1417 libdbi to communicate with the database(s).
1418 * interface plugin: Use the ignorelist framework when selecting /
1419 ignoring interfaces. This allows one to use regular expressions to
1420 select interfaces, too.
1421 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1422 Thanks to Bruno Prémont for this patch.
1423 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1424 for the patch.
1425 * mysql plugin: Allow connecting to a database via the UNIX domain
1426 socket, too. Thanks to Mirko Buffoni for the patch.
1427 * network plugin: Further performance improvements for the receive
1428 code. This hopefully will help very large setups.
1429 * openvpn plugin: This new plugin collects statistics provided by the
1430 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1431 * oracle plugin: This new plugin allows you to connect to an Oracle
1432 database and use SQL to gather custom statistics from it. It is
1433 similar to the already existing PostgreSQL plugin.
1434 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1435 have been added.
1436 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1437 * perl plugin: Added support for `notification meta data'.
1438 * perl plugin: Added support for the `filter chain' infrastructure by
1439 allowing plugins to register `matches' and `targets'.
1440 * postgresql plugin: The preferred configuration syntax has been
1441 updated to be in line with the syntax used by the new dbi and oracle
1442 plugins. The compatibility code for the old syntax is present.
1443 Support for the new `Result' blocks and the interval parameter has
1444 been added.
1445 * processes plugin: Stacksize and virtual memory usage statistics have
1446 been added. Portability fixes.
1447 * rrdcached plugin: This new plugin uses the (still in development)
1448 RRD accelerator daemon, rrdcached. This daemon works very similar to
1449 the original rrdtool plugin of collectd, but adds some more nice
1450 features.
1451 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1452 added.
1454 2009-05-09, Version 4.5.4
1455 * Build system, various plugins: Many build fixes for FreeBSD,
1456 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1457 for many fixes and providing a build system for many platforms,
1458 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1459 providing an OpenBSD system.
1460 * collectd: Fix a potential race condition when creating directories.
1461 * battery plugin: Don't complain about a missing directory every
1462 interval.
1463 * dns plugin: Slight portability fixes.
1464 * exec plugin: Allow executed programs to close STDERR. Thanks to
1465 Thorsten von Eicken for reporting this problem.
1466 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1467 Tomasz Pala for the patch.
1468 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1469 the patch.
1470 * rrdtool plugin: Fix a possible race condition: If the network plugin
1471 is initialized and dispatches a value before the rrdtool plugin is
1472 initialized, the daemon may crash.
1473 * memory plugin: Fix a potential problem under Solaris.
1475 2009-02-22, Version 4.5.3
1476 * build system: The check for libupsclient even when `pkg-config' is
1477 not available.
1478 * collectd: Fix error handling in the global cache.
1479 * Collectd::Unixsock: Error handling has been improved.
1480 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1481 patch.
1482 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1483 faults. Thanks to Peter Holik for his patch.
1484 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1485 code. Thanks to "thated" for reporting this.
1487 2009-01-02, Version 4.5.2
1488 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1489 file may be in both locations, especially when the database was
1490 installed in a non-standard path. Thanks to Dusty Doris for
1491 reporting this.
1492 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1493 Solaris, in the configure script automatically.
1494 * build system, tcpconns plugin: Check for `kvm_nlist' and
1495 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1496 library with similar functions to the BSD variant, but doesn't
1497 provide these necessary functions.
1498 * collectd.conf(5): Various fixes and clarifications.
1499 * collectd: Remove a GNUism (unnamed unions), thus improving
1500 portability.
1501 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1502 This solves portability problems, especially for Solaris.
1503 * dns plugin: Fix a portability problem with NetBSD.
1504 * filecount plugin: Fix an off-by-one error. This error may cause a
1505 segmentation fault.
1506 * network plugin: Fix the handling of `type' in the network protocol.
1507 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1508 much larger buffer. This caused the `type' to be transferred much
1509 more often than necessary. In some cases, e. g. the `cpu' and
1510 `cpufreq' plugins being used at the same time, data may be corrupted
1511 in those files. Thanks to Bruno Prémont for debugging and reporting
1512 this issue.
1513 * processes plugin: Fix a possible segmentation fault when specifying
1514 invalid configuration options.
1515 * unixsock plugin: Make sure the initialization function is run only
1516 once. This resolves a file descriptor leak under systems which run
1517 the initialization more than once, such as Solaris.
1519 2008-10-16, Version 4.5.1
1520 * build system: Change `--enable-<plugin>' to abort with an error if
1521 dependencies are not met. Thanks to Bruno Prémont for the patch.
1522 Also, the poisoning of various string functions has been restricted
1523 to debug builds.
1524 * collectd: Fix a memory leak in the global value cache. With every
1525 *missing* value a couple of bytes would be leaked. Another memory
1526 leak in the configuration handling code has been fixed. Thanks to
1527 Niraj Tolia for reporting these issues.
1528 * collectd: Fix an off-by-one error in the ignorelist functionality.
1529 When using regular expressions, the last character would be missing,
1530 possibly matching differently from what one would expect.
1531 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1532 problem.
1533 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1534 Linzberger for reporting the bug.
1535 * iptables plugin: Fix an off-by-one error. If a string was just one
1536 character too long, it was truncated instead of reporting an error.
1537 * network plugin: Fix a memory leak in the configuration handling
1538 code. Thanks to Niraj Tolia for reporting this issue.
1539 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1540 * postgresql plugin: Don't reopen connection during reinitialization.
1541 This fixes a bug under Solaris and potentially other platforms.
1542 Missing calls to `PQclear' have been added, too. This fixes memory
1543 leaks. Thanks to ``Admin'' for reporting these bugs.
1544 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1545 library.
1546 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1547 problems with some `libc's. Thanks to Matthias Lay for reporting the
1548 bug.
1550 2008-09-04, Version 4.5.0
1551 * collectd: Added the ability to flush certain identifiers.
1552 * collectd: The concept of `notification meta data' has been
1553 introduced.
1554 * filecount plugin: The new filecount plugin counts the number of
1555 files in a directory and its subdirectories.
1556 * ipmi plugin: Sensor names have been changed to ensure unique names.
1557 Notifications upon added and removed sensors can now be generated.
1558 * notify_desktop plugin: This new plugin sends notifications to the
1559 X desktop using the structure defined in the `Desktop Notification
1560 Specification'.
1561 * notify_email plugin: This new plugin sends out notifications via
1562 email, using the `esmtp' library.
1563 * onewire plugin: The new experimental(!) onewire plugin reads values,
1564 such as temperatures, from sensors connected to the computer via the
1565 onewire bus.
1566 * perl plugin: Improved synchronized access to internal data structures
1567 and fixed a possible dead-lock.
1568 * perl plugin: Added the ability to flush certain identifiers and marked
1569 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1570 plugin_flush().
1571 * perl plugin: Added the ability to configure Perl plugins.
1572 * postgresql plugin: The new postgresql plugin collects statistics
1573 about or from a PostgreSQL database.
1574 * processes plugin: The `ProcessMatch' option has been added.
1575 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1576 IO load.
1577 * tcpconns plugin: This plugin has been ported to OpenBSD.
1578 * thermal plugin: The new thermal plugin collects system temperatures
1579 using Linux ACPI thermal zone data.
1581 2009-01-02, Version 4.4.5
1582 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1583 file may be in both locations, especially when the database was
1584 installed in a non-standard path. Thanks to Dusty Doris for
1585 reporting this.
1586 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1587 Solaris, in the configure script automatically.
1588 * collectd.conf(5): Various fixes and clarifications.
1589 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1590 portability problems, especially for Solaris.
1591 * dns plugin: Fix a portability problem with NetBSD.
1592 * network plugin: Fix the handling of `type' in the network protocol.
1593 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1594 much larger buffer. This caused the `type' to be transferred much
1595 more often than necessary. In some cases, e. g. the `cpu' and
1596 `cpufreq' plugins being used at the same time, data may be corrupted
1597 in those files. Thanks to Bruno Prémont for debugging and reporting
1598 this issue.
1599 * unixsock plugin: Make sure the initialization function is run only
1600 once. This resolves a file descriptor leak under systems which run
1601 the initialization more than once, such as Solaris.
1603 2008-10-16, Version 4.4.4
1604 * build system: Change `--enable-<plugin>' to abort with an error if
1605 dependencies are not met. Thanks to Bruno Prémont for the patch.
1606 Also, the poisoning of various string functions has been restricted
1607 to debug builds.
1608 * collectd: Fix a memory leak in the global value cache. With every
1609 *missing* value a couple of bytes would be leaked. Another memory
1610 leak in the configuration handling code has been fixed. Thanks to
1611 Niraj Tolia for reporting these issues.
1612 * collectd: Fix an off-by-one error in the ignorelist functionality.
1613 When using regular expressions, the last character would be missing,
1614 possibly matching differently from what one would expect.
1615 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1616 problem.
1617 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1618 Linzberger for reporting the bug.
1619 * network plugin: Fix a memory leak in the configuration handling
1620 code. Thanks to Niraj Tolia for reporting this issue.
1621 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1622 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1623 problems with some `libc's. Thanks to Matthias Lay for reporting the
1624 bug.
1626 2008-09-01, Version 4.4.3
1627 * collectd: Fix a memory leak in the threshold checking code.
1628 * memcached plugin: Fix a too short timeout and a related file
1629 descriptor leak.
1630 * memory plugin: A typo in the libstatgrab code has been fixed.
1631 * snmp plugin: Fix a possible memory leak.
1633 2008-07-15, Version 4.4.2
1634 * build system: Use pkg-config to detect the upsclient library.
1635 * collectd: Try even harder to determine the endianness of the
1636 architecture collectd is being built on.
1637 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1638 of disks.
1639 * dns plugin: Fix compilation errors with BIND versions 19991001
1640 through 19991005.
1641 * network plugin: Bugfix in the init routine: The init function
1642 cleared a buffer regardless of its contents. This could lead to lost
1643 values under Solaris.
1644 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1645 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1646 function.
1647 * wireless plugin: Work around incorrect noise and power values
1648 returned by some broken drivers.
1650 2008-06-03, Version 4.4.1
1651 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1652 to kyrone for reporting this.
1653 * collectd: Fixed min/max output in notifications generated by
1654 threshold checking.
1655 * collectd-nagios: Fix the protocol used to communicate with the
1656 daemon.
1657 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1658 initialization has errors. An issue with Perl 5.10 has been fixed.
1659 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1660 René Rebe and Siegmund Gorr for reporting this.
1662 2008-05-06, Version 4.4.0
1663 * collectd: Internal code cleanups.
1664 * collectd: Added support for a `Flush' command in the unixsock and
1665 exec plugins. This command can be used to force a plugin (or all) to
1666 flush its values to disk.
1667 * collectd: Thresholds can now be configured to apply to one data
1668 source only, making it possible to configure different thresholds
1669 for each data source.
1670 * apache, nginx plugins: Added the possibility to disable host and/or
1671 peer verification.
1672 * ascent plugin: The new ascent plugin reads and parses the statistics
1673 page of an Ascent server.
1674 * cpu plugin: Support for the statgrab library has been added.
1675 * disk plugin: The possibility to ignore certain disks or collect only
1676 specific disks has been added.

1678 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1679 sensor values via IPMI, the intelligent platform management
1680 interface.
1681 * iptables plugin: The iptc library that is used by the iptables
1682 plugin has been added to the distribution, because it is not
1683 provided by all distributions and removed from at least one.
1684 * powerdns plugin: The new powerdns plugin reads statistics from an
1685 authoritative or a recursing PowerDNS name server.
1686 * rrdtool plugin: The size of the files generated with the default
1687 configuration has been decreased.

1717 they are in non-standard paths.
1718 * build system: Portability fixes: Automatically define "_REENTRANT"
1719 if the libc expects it.
1720 * collectd: Error and warning messages have been improved.
1721 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before

1726 the program.
1727 * hddtemp plugin: Error and warning messages have been improved.
1728 * sensors plugin: Fix sensor collection for some chip types.
1730 2008-03-29, Version 4.3.2
1731 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1732 `Persist' threshold options.
1733 * collectd: Fix handling of missing values in the global value cache.
1734 * collectd: Improved error messages when parsing the configuration.
1735 * sensors plugin: Fix temperature collection with libsensors4.
1736 * unixsock plugin: Fix mixed input and output operation on streams.
1737 * wireless plugin: Fix reading noise value.
1739 2008-03-05, Version 4.3.1
1740 * exec plugin: Set supplementary group IDs.
1741 * network plugin:
1742 + Use `memcpy' when constructing/parsing a package to avoid
1743 alignment problems on weird architectures, such as Sparc.
1744 + Translate doubles to/from the x86 byte representation to ensure
1745 cross-platform compatibility.
1746 * ping plugin: Correct the handling of the `TTL' setting.
1747 * swap plugin: Reapply a patch for Solaris.
1748 * tcpconns plugin: Portability improvements.
1750 2008-02-18, Version 4.3.0
1751 * collectd: Notifications have been added to the daemon. Notifications
1752 are status messages that may be associated with a data instance.
1753 * collectd: Threshold checking has been added to the daemon. This
1754 means that you can configure threshold values for each data
1755 instance. If this threshold is exceeded a notification will be
1756 created.
1757 * collectd: The new `FQDNLookup' option tells the daemon to use the
1758 full qualified domain name as the hostname, not just the host part
1759 es returned by `gethostname(2)'.
1760 * collectd: Support for more than one `TypesDB' file has been added.
1761 This is useful when one such file is included in a package but one
1762 wants to add custom type definitions.
1763 * collectd: The `Include' config option has been expanded to handle
1764 entire directories and shell wildcards.
1765 * collectdmon: The new `collectdmon' binary detects when collectd
1766 terminates and automatically restarts it again.
1767 * csv plugin: The CSV plugin is now able to store counter values as a
1768 rate, using the `StoreRates' configuration option.
1769 * exec plugin: Handling of notifications has been added and the
1770 ability to pass arguments to the executed programs has been added.
1771 * hddtemp plugin: The new `TranslateDevicename' option lets you
1772 disable the translation from device names to major-minor-numbers.
1773 * logfile plugin: Handling of notifications has been added.
1774 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1775 domain name lookups in this plugin.
1776 * perl plugin: Many internal changes added support for handling multiple
1777 threads making the plugin reasonably usable inside collectd. The API has
1778 been extended to support notifications and export global variables to
1779 Perl plugins; callbacks now have to be identified by name rather than a
1780 pointer to a subroutine. The plugin is no longer experimental.
1781 * uuid plugin: The new UUID plugin sets the hostname to an unique
1782 identifier for this host. This is meant for setups where each client
1783 may migrate to another physical host, possibly going through one or
1784 more name changes in the process. Thanks to Richard Jones from
1785 Red Hat's Emerging Technology group for this plugin.
1786 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1787 CPU, disk and network statistics about guest systems on the same
1788 physical server. Thanks to Richard Jones from Red Hat's Emerging
1789 Technology group for this plugin.
1791 2008-04-22, Version 4.2.7
1792 * build system: Improved detection of several libraries, especially if
1793 they are in non-standard paths.

1798 using them.
1799 * apache plugin: Allocate new memory when reading a webpage instead of
1800 using a buffer of static size.
1801 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1802 the program.
1803 * hddtemp plugin: Error and warning messages have been improved.
1804 * sensors plugin: Fix sensor collection for some chip types.
1806 2008-03-29, Version 4.2.6
1807 * collectd: Improved error messages when parsing the configuration.
1808 * sensors plugin: Fix temperature collection with libsensors4.
1809 * unixsock plugin: Fix mixed input and output operation on streams.
1810 * wireless plugin: Fix reading noise value.
1812 2008-03-04, Version 4.2.5
1813 * apache plugin: Improved initialization and error messages.
1814 * exec plugin: Set supplementary group IDs.
1815 * network plugin:
1816 + Create separate threads for reading from the socket and parsing
1817 and dispatching incoming packets. Versions prior to this may have
1818 problems in high-load situations, where the socket receive buffers
1819 overflows, resulting in gaps in the data.
1820 + Use `memcpy' when constructing/parsing a package to avoid
1821 alignment problems on weird architectures, such as Sparc.
1822 + Translate doubles to/from the x86 byte representation to ensure
1823 cross-platform compatibility.
1824 * ping plugin: Correct the handling of the `TTL' setting.
1825 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1826 * swap plugin: Reapply a patch for Solaris.
1827 * tcpconns plugin: Portability improvements.
1829 2008-01-21, Version 4.2.4
1830 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1831 the permission on the socket as documented in the manpage. Thanks to
1832 Evgeny Chukreev for fixing this issue.
1833 * collectd: The documentation has been improved.
1835 2007-12-28, Version 4.2.3
1836 * sensors plugin: Updated the plugin to build and work with version 3
1837 of the libsensors library.
1839 2007-12-15, Version 4.2.2
1840 * nginx plugin: Incorrect comparison of strings lead to a segfault
1841 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1842 this.
1843 * logfile plugin: The config option `Timestamp' was handled
1844 incorrectly and basically always active. Thanks to Luke Heberling
1845 for fixing this.
1847 2007-11-08, Version 4.2.1
1848 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1849 enabled on the host.
1850 * snmp plugin: Fix a memory leak.
1852 2007-10-27, Version 4.2.0
1853 * collectd: The new config option `Include' lets you include other
1854 configfiles and thus split up your config into smaller parts. This
1855 may be especially interesting for the snmp plugin to keep the data
1856 definitions separate from the host definitions.
1857 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1858 (number of connections, octets and packets for each service and
1859 destination). Thanks to Sebastian Harl for this plugin.
1860 * memcached plugin: The new `memcached' plugin connects to a memcached
1861 daemon process and collects statistics of this distributed caching
1862 system. Thanks to Antony Dovgal for contributing this plugin.
1863 * nginx plugin: The new `nginx' plugin reads the status page of an
1864 nginx daemon and saves the handled connections and requests.
1865 * perl plugin: Many changes, including the added `EnableDebugger'
1866 config option which lets you debug your Perl plugins more easily.
1867 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1868 be more thread-safe otherwise by locking calls to the library.
1869 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1870 correct the values returned by SNMP-agents. If a <data> block is
1871 defined as `table' the instance is now optional. The sequence number
1872 is used as the type-instance in this case. The new `InstancePrefix'
1873 option allows to add arbitrary prefixes to the type-instance.
1874 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1875 certain TCP connections and what state they're in. This can be used
1876 to see how many connections your FTP server has to handle or how
1877 many outgoing connections your mailserver has open.
1879 2008-01-11, Version 4.1.6
1880 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1881 the permission on the socket as documented in the manpage. Thanks to
1882 Evgeny Chukreev for fixing this issue.
1883 * collectd: The documentation has been improved.
1885 2007-12-27, Version 4.1.5
1886 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1887 memory situations.
1888 * sensors plugin: Updated the plugin to build and work with version 3
1889 of the libsensors library.
1891 2007-11-08, Version 4.1.4
1892 * Build system: Improve detection of the rrd library, especially if
1893 it's in a non-standard location.
1894 * Build system: A bug when parsing the argument for
1895 `--with-libnetsnmp' has been fixed.
1896 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1897 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1898 a deadlock or delay when shutting down the daemon.
1899 * snmp plugin: Fix a memory leak.
1901 2007-10-24, Version 4.1.3
1902 * collectd: A build issue under Solaris has been resolved by renaming
1903 data types.
1904 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1905 be more thread-safe otherwise by locking calls to the library.
1907 2007-09-28, Version 4.1.2
1908 * apcups plugin: Fix reporting of the `load percent' data.
1909 * wireless plugin: Correct the handling of cards returning signal and
1910 noise quality as percentage.
1911 * perl plugin: Fix a possible buffer overflow in get_module_name().
1912 * build system: Further improve the detection of libraries.
1913 * netlink plugin: Build issues under some older versions of the Linux
1914 includes (i. e. Debian Sarge) have been fixed.
1915 * snmp plugin: Fix a potential segfault when a host times out. Add
1916 support for the `timeticks' type.
1918 2007-09-12, Version 4.1.1
1919 * Build system: The detection of `libnetlink' has been improved.
1920 * collectd: The documentation has been fixed in numerous places.
1921 * exec plugin: Setting the group under which to run a program has been
1922 fixed.
1923 * collectd: The `sstrerror' function was improved to work correctly
1924 with the broken GNU version of `strerror_r'.
1925 * collectd: Write an error message to STDERR when loading of a plugin
1926 fails.
1927 * apcups plugin: Fix the `types' used to submit the values: They still
1928 has an `apcups_' prefix which doesn't work anymore.
1929 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1930 whatever the client thinks is `now'..
1932 2007-09-01, Version 4.1.0
1933 * Build system: The build system has been changed to automatically
1934 disable all plugins, which are missing dependencies. The dependency
1935 checking has been removed from the plugins themselves to remove
1936 redundancy.
1937 * Flexible interval: The interval of collected data is now sent along
1938 with the data itself over the network, so that the interval-settings
1939 of server and clients no longer needs to match.
1940 * netlink plugin: The new `netlink' plugin connects to the Linux
1941 kernel using a netlink socket and uses it to query information about
1942 interfaces, qdiscs and classes.
1943 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1944 to not block data collection.
1945 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1946 network devices, such as switches, routers, thermometers, rack
1947 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1948 plugin.
1949 * unixsock plugin: Added the `LISTVAL' command.
1950 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1951 of music played with xmms.
1953 2007-09-28, Version 4.0.9
1954 * apcups plugin: Fix reporting of the `load percent' data.
1955 * wireless plugin: Correct the handling of cards returning signal and
1956 noise quality as percentage.
1957 * perl plugin: Fix a possible buffer overflow in get_module_name().
1959 2007-09-12, Version 4.0.8
1960 * collectd: The `sstrerror' function was improved to work correctly
1961 with the broken GNU version of `strerror_r'.
1962 * collectd: Write an error message to STDERR when loading of a plugin
1963 fails.
1964 * apcups plugin: Fix the `types' used to submit the values: They still
1965 has an `apcups_' prefix which doesn't work anymore.
1966 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1967 whatever the client thinks is `now'..
1969 2007-08-26, Version 4.0.7
1970 * documentation: Some typos have been fixed and some information has
1971 been improved.
1972 * build system: Many fixes for detecting libraries in unusual places,
1973 such as on RedHat systems. The affected libraries are `libcurl',
1974 `libmysql', and `libupsclient'.
1975 * network plugin: Allow the `Port' option to be specified as a number
1976 (i. e. without quotes).
1977 * nut plugin: A fix allows linking the nut plugin against
1978 libupsclient, version >= 2.2.0.
1979 * processes plugin: Fix a potential segmentation fault.
1981 2007-07-30, Version 4.0.6
1982 * sensors plugin: Fix the ignorelist functionality: Only the `type
1983 instance' was used to match against the list, but the documentation
1984 told otherwise. This release fixes the code, so it complies with the
1985 documentation.
1986 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1987 configuration messages will end up in the logging facility.
1988 * conrtib/fedora: The contributed specfile for Fedora has been
1989 updated.
1991 2007-07-05, Version 4.0.5
1992 * Portability: More fixes for OpenBSD have been included.
1994 2007-06-24, Version 4.0.4
1995 * cpu plugin: Fixed the Solaris code.
1996 * dns plugin: Fixed a build issue for OpenBSD.
1997 * interface plugin: Fixed the Solaris code.
1998 * load plugin: Fixed the alternative `/proc' Linux code.
1999 * memory plugin: Fixed the Solaris code.
2000 * oconfig: Don't require `-lfl' anymore.
2002 2007-06-19, Version 4.0.3
2003 * cpu plugin: Fix the Darwin / Mac OS X code.
2004 * ping plugin: Use the return value of `getpid', not its address.
2005 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2006 initialized correctly.
2007 * configure: Added `--with-nan-emulation' to aid cross compilation.
2009 2007-06-12, Version 4.0.2
2010 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2011 they're given in numerically form.
2013 2007-06-07, Version 4.0.1
2014 * iptables plugin: A bug in the configuration routine has been fixed.
2015 Setting a comment in the configfile will no longer cause a
2016 segmentation fault.
2018 2007-06-03, Version 4.0.0
2019 * collectd: The plugin-infrastructure has been changed to allow for
2020 more types of plugins, namely `write' and `log' plugins.
2021 * collectd: The read-function has been changed to read many plugins in
2022 parallel, using threads. Thus, plugins generally need to use
2023 thread-safe functions from now on.
2024 * collectd: The '-t' command line options allows to perform syntax tests
2025 of the configuration file and exit immediately.
2026 * csv plugin: The new `csv' plugin handles output to `comma separated
2027 values'-files.
2028 * rrdtool plugin: The new `rrdtool' plugin handles output to
2029 RRD-files. Data can be cached to combine multiple updates into one
2030 write to increase IO-performance.
2031 * network plugin: The new `network' plugin handles IO via the network.
2032 It implements a different, much more extensible protocol which can
2033 combine many values in one packet, decreasing the number of UDP-
2034 packets being sent. It can read from and send to the network and
2035 with the appropriate configuration even forward packets to other
2036 networks.
2037 * unixsock plugin: The new `unixsock' plugin provides an interface to
2038 communicate with the daemon while it is running. Right now the
2039 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2040 come.
2041 * perl plugin: The new `perl' plugin allows you to write extensions
2042 for collectd in the scripting-language Perl.
2043 * logfile plugin: The new `logfile' plugin writes logmessages to files
2044 or STDOUT or STDERR.
2045 * syslog plugin: The new `syslog' plugin sends logmessages to the
2046 system's syslog daemon.
2047 * entropy plugin: The new `entropy' plugin collects the amount of
2048 entropy currently being available to the system.
2049 * exec plugin: The new `exec' plugin forks child processes and reads
2050 back values provided by the forked processes.
2051 * iptables plugin: The new `iptables' plugin reads counters from
2052 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2053 plugin.
2054 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2055 to Peter Holik for contributing this plugin.
2056 * nut plugin: The new `nut' plugin connects the upsd of the `network
2057 ups tools' and reads information about the connected UPS.
2058 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2059 connections) field was added by Florent Monbillard.
2060 * collectd-nagios: The new `collectd-nagios' binary queries values
2061 from collectd, parses them and exits according to Nagios-standards.
2062 * manpages: The manpages have been improved a lot.
2064 2007-09-28, Version 3.11.7
2065 * wireless plugin: Correct the handling of cards returning signal and
2066 noise quality as percentage.
2068 2007-08-31, Version 3.11.6
2069 * processes plugin: Fix a potential segmentation fault.
2071 2007-05-29, Version 3.11.5
2072 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2073 * ntpd plugin: Fix a potential buffer overflow.
2074 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2075 were accounted as `zombies'.
2077 2007-04-10, Version 3.11.4
2078 * dns plugin: Change the order of includes to make the plugin compile
2079 under FreeBSD.
2081 2007-03-30, Version 3.11.3
2082 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2083 of the unused `COLLECT_KSTAT'.
2085 2007-02-11, Version 3.11.2
2086 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2087 NULL-pointer may have been passed to `printf' which causes a
2088 segfault with some libcs.
2090 2007-02-10, Version 3.11.1
2091 * df plugin: Some wrong defines have been fixed so the plugin works
2092 under Solaris again.
2093 * dns plugin: The usage of a struct has been fixed to work with
2094 non-GNU libcs.
2095 * processes plugin: Some missing defines have been added so the plugin
2096 compiles cleanly under FreeBSD and presumably other UNIXes.
2098 2006-12-22, Version 3.11.0
2099 * collectd: The new command line option `-P' makes it easier for
2100 distributors to change the location of PID-files.
2101 * collectd: The daemon shuts down faster now which makes it easier to
2102 write init.d-scripts for it.
2103 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2104 caused problems every now and then.
2105 * df plugin: New config options allow to ignore certain mountpoints,
2106 filesystem types or devices.
2107 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2108 and interprets it. It collects traffic as well as qtype, opcode and
2109 rcode counts.
2110 * email plugin: Sebastian Harl has contributed this plugin which
2111 counts received mails in categories (e. g. ham, spam, virus), spam
2112 score (as given by SpamAssassin) and check types.
2113 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2114 uses `mbmon' to gather information from sensors on the motherboard.
2115 * processes plugin: Collect detailed statistics for configured
2116 processes, that's process and thread count, CPU usage, resident
2117 segment size and pagefaults.
2118 * multimeter plugin: Peter Holik contributed a new plugin which
2119 queries multimeters.
2120 * sensors plugin: Lubos Stanek has put much effort into improving this
2121 plugin, including `extended naming', collection of voltage values
2122 and the possibility to ignore certain values.
2124 2006-12-21, Version 3.10.4
2125 * Max Kellermann has identified a bug in the server routine: When
2126 opening a socket fails the daemon will (re)try opening the socket in
2127 an endless loop, ultimately leading to a `EMFILE' error.
2129 2006-11-04, Version 3.10.3
2130 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2131 ntpd's reply was sent in more than one packet, the buffer size was
2132 calculated incorrectly, resulting in the reading of uninitialized or
2133 freed memory.
2135 2006-11-01, Version 3.10.2
2136 * The sample config file has been improved.
2137 * Errors in the manpages have been corrected.
2138 * The ping-plugin now adds hosts during initialization, not during
2139 startup. This speeds up startup when no network connectivity is
2140 available. Also, the hosts are being added later when the network is
2141 available.
2142 * Improved BSD-support for the df-plugin.
2143 * Fixed syntax errors in the swap-plugin for Mac OS X.
2144 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2145 plugin.
2146 * Don't disable the mysql-plugin if connecting to the database fails
2147 during initialization. Instead, try again in increasing intervals.
2149 2006-07-19, Version 3.10.1
2150 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2151 the apcups cannot be reached, unconnected sockets will pile up and
2152 eventually lead to `Too many open files' errors.
2154 2006-07-09, Version 3.10.0
2155 * The `disk' plugin has been ported to Darwin.
2156 * The `battery' plugin should work on many Apple computers now.
2157 * The `traffic' plugin can now ignore certain interfaces. Also,
2158 statistics for sent/received packets and errors have been added.
2159 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2160 to Anthony Gialluca for contributing this plugin and providing me
2161 with a test environment :)
2162 * A plugin for monitoring an NTP instance and the local clock drift
2163 has been added.
2165 2006-06-25, Version 3.9.4
2166 * The Solaris code in the `swap' plugin has been changed to reflect
2167 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2168 working this out.
2169 * The debugging system has been fixed to work with the Sun libc.
2170 * When built without librrd the variable `operating_mode' could be
2171 uninitialized. Thanks to David Elliot for reporting the bug.
2173 2006-06-01, Version 3.9.3
2174 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2175 operating systems also profit from the changes, but I wasn't able to
2176 check that.
2177 * Changed the build system to find the netinet-includes under FreeBSD
2178 and therefore successfully build the `liboping' library there.
2180 2006-05-09, Version 3.9.2
2181 * Applied a patch to the `liboping' library. Due to a bug in the
2182 sequence checking the `ping' plugin stopped working after
2183 approximately 7.6 days.
2185 2006-05-09, Version 3.8.5
2186 * Applied a patch to the `liboping' library. Due to a bug in the
2187 sequence checking the `ping' plugin stopped working after
2188 approximately 7.6 days.
2190 2006-04-21, Version 3.9.1
2191 * Build issues with Solaris and possible other architectures have been
2192 resolved.
2193 * Problems when building the `apache'-plugin without `libcurl' have
2194 been resolved.
2195 * A bug in the `ping' plugin has been fixed. Sorry folks.
2197 2006-04-02, Version 3.9.0
2198 * A plugin to monitor the Apache webserver has been added.
2199 <http://httpd.apache.org/>
2200 * A plugin to collect statistics about virtual servers using VServer.
2201 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2202 this plugin :)
2203 * A plugin for wireless LAN cards has been added. It monitors signal
2204 strength, link quality and noise ratio..
2205 * A plugin for Apple hardware sensors has been added.
2206 * An option to compile collectd with different `step' and `heartbeat'
2207 settings has been added. The size of RRAs is no longer static but
2208 calculated based on the settings for `step' and `width'.
2209 * The `ping' plugin can now be configured to use a certain TTL.
2210 * A plugin to monitor the hardware sensors of Apple computers has been
2211 added.
2212 * The plugins `cpu', `memory', `processes' and `traffic' have been
2213 ported to Mach/Darwin (Mac OS X).
2214 * The `log mode' has been contributed by Christophe Kalt. It writes
2215 the data into text files rather than RRD files.
2217 2006-04-09, Version 3.8.4
2218 * Applied patch by Vincent Stehlé which improves the disk-name
2219 resolution in the `hddtemp' plugin for Linux systems.
2221 2006-04-02, Version 3.8.3
2222 * Applied a patch by James Byers: The MySQL plugin was not working
2223 with MySQL 5.0.2 or later.
2225 2006-03-14, Version 3.8.2
2226 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2227 the GNU libc, because it points to `/etc/fstab' rather than
2228 `/etc/mtab'.
2230 2006-03-13, Version 3.8.1
2231 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2232 * Fixes in the debian `postinst' and `init.d' scripts.
2234 2006-03-09, Version 3.8.0
2235 * The `ping' plugin no longer uses `libping' but a self written
2236 library named `liboping'. With this library it's possible to ping
2237 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2239 2006-02-18, Version 3.7.2
2240 * A simple bug in the `battery' plugin has been fixed. It should now
2241 work with ACPI based batteries as well. Thanks to Sebastian for
2242 fixing this.
2243 * Fixing a bug that prevented collectd to be built without librrd.
2244 Thanks to Werner Heuser for reporting it.
2246 2006-02-04, Version 3.7.1
2247 * The new network code has been improved to build with older versions
2248 of glibc.
2249 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2250 to Tommie Gannert for this patch.
2252 2006-01-30, Version 3.7.0
2253 * The `battery' plugin has been added. It collects information about
2254 laptop batteries..
2255 * The MySQL plugin has been improved: It now writes two more RRD
2256 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2257 * The `cpufreq' plugin now reads another file since the file it did
2258 read so far causes much overhead in the kernel. Also, you need root
2259 to read the old file, but not to read the new one.
2260 * The `hddtemp' plugin can now be configured to connect to another
2261 address and/or port than localhost.
2262 * The `df' plugin now prefers `statvfs' over `statfs'.
2263 * The network code has been rewritten. collectd now supports unicast
2264 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2265 be set in the configfile.
2267 2006-01-24, Version 3.6.2
2268 * Due to a bug in the configfile handling collectd wouldn't start in
2269 client mode. This released fixes this.
2271 2006-01-20, Version 3.6.1
2272 * Due to a bug in `configure.in' all modules and the binary were
2273 linked against `libmysqlclient'. This issue is solved by this
2274 release.
2276 2006-01-17, Version 3.6.0
2277 * A config file has been added. This allows for loading only specific
2278 plugins.
2279 * A `df' plugin has been added.
2280 * A `mysql' plugin has been added.
2281 * The `ping' plugin doesn't entirely give up hope when a socket error
2282 occurred, but will back of and increase the intervals between tries.
2284 2006-01-21, Version 3.5.2
2285 * Fixed yet another bug in the signal handling.. Stupid typo..
2286 * Improved the ping plugin to not give up on socket errors (backport
2287 from 3.6.0).
2289 2005-12-18, Version 3.5.1
2290 * The PID-file is now deleted correctly when shutting down the daemon.
2291 * SIGINT and SIGTERM are now handled correctly.
2293 2005-12-16, Version 3.5.0 (Revision 326)
2294 * A bug in the `load' module under Solaris has been fixed.
2295 * The `users' module has been contributed by Sebastian Harl. It counts
2296 currently logged in users.
2297 * The CPU module now works under FreeBSD without the use of
2298 `libstatgrab', however SMP support is missing.
2299 * The default directories for the RRD files and the PID file now
2300 depend on the compile time setting of `localstatedir'.
2302 2005-11-15, Version 3.4.0 (Revision 236)
2303 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2304 from gentoo's bugzilla for writing the patch.
2305 * The build dependency for librrd has been removed. Binaries built
2306 without librrd are client-only and will multicast their value as
2307 with the `-c' argument.
2308 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2309 * The newly introduced `-f' switch prevents daemon initialization
2310 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2311 Barcellos for this patch.
2313 2005-11-04, Version 3.3.0 (Revision 216)
2314 * New modules have been added:
2315 - `serial', for monitoring traffic on the serial interfaces
2316 - `nfs', for graphing NFS procedure calls
2317 - `tape', traffic from/to tape devices
2318 * The memory.rrd now accepts more than 4Gig of memory.
2320 2005-10-26, Version 3.2.0 (Revision 200)
2321 * Support for graphing the processes has been added (thanks to Lyonel
2322 Vincent)
2323 * If reading from hddtemp fails collectd will increase the time
2324 between polls up to one day.
2325 * The init.d files have been improved.
2326 * Problems with the spec file have been fixed.
2328 2005-10-16, Version 3.1.0 (Revision 194)
2329 * Added the `setsid' syscall to the startup code.
2330 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2332 2005-09-30, Version 3.0.0 (Revision 184)
2333 * The ability to send/receive data to/from the network (think
2334 multicast) has been added.
2335 * Modules have been split up into shared libraries can be loaded at
2336 runtime. The biggest advantage is that the core program doesn't need
2337 to be linked against an external library.
2338 * A patch by George Kargiotakis has been applied: It fixes the sensors
2339 behaviour then more than one sensor is being queried.
2341 2005-09-16, Version 2.1.0 (Revision 172)
2342 * A module for swap statistics has been added.
2344 2005-09-09, Version 2.0.0 (Revision 135)
2345 * Filenames can no longer be configured at program startup. The only
2346 options as of this version are the directory and ping hosts.
2347 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2348 Soft-IRQ statistics are added to `System'.
2349 * Diskstats now collect read and write bytes, not sectors.
2350 * Ping statistics can now be collected for more than one host. There
2351 is no default any more: If no host is given no host will be pinged.
2352 * A self-written patch for libping has been applied so it builds
2353 cleanly.
2355 2005-09-01, Version 1.8.1 (Revision 123)
2356 * Much improved configure-script: libraries and features may now be
2357 disabled.
2358 * More detailed warnings/error messages when RRD update fails.
2360 2005-08-29, Version 1.8.0:
2361 * Support for collecting disk statistics under Solaris.
2363 2005-08-25, Version 1.7.0:
2364 * Support for libstatgrab[1] for load, memory usage and network
2365 traffic. CPU- and disk-usage are not (yet) supported, since
2366 libstatgrab returns insufficient information. I will contact the
2367 authors.
2368 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2369 aren't necessarily counted linear which is now handled correctly.
2370 [1]: http://www.i-scream.org/libstatgrab/
2372 2005-08-21, Version 1.6.0:
2373 * Basic support for Solaris: System load and cpu-usage can be
2374 collected under Solaris, too. Other stats will follow later.
2375 * Many fixes in the autoconf-script
2376 * Collection/Museum scripts have been added under contrib/museum
2377 * collectd may now be started in unprivileged mode, though ping
2378 statistics will not work.
2380 2005-07-17, Version 1.5.1:
2381 * Diskstats-RRDs now use major/minor for naming. Some systems have
2382 weird strings as disk-names..
2384 2005-07-17, Version 1.5:
2385 * A new module, diskstats, has been added. It collects information
2386 about the disks and partitions.
2388 2005-07-11, Version 1.4.2:
2389 * The meminfo module has been changed to work with more platforms
2390 and/or kernel versions.
2392 2005-07-10, Version 1.4.1: Correct traffic stats
2393 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2394 forgot to correct when I changed that module.
2396 2005-07-09, Version 1.4: More traffic stats
2397 * Traffic is now collected for all interfaces that can be found
2398 * Temperature-statistics are read from lm-sensors if available
2400 2005-07-08, Version 1.3: CPU stats
2401 * Collecting CPU statistics now
2403 2005-07-12, Version 1.2: Using syslog
2404 * collectd is now using the syslog facility to report errors, warnings
2405 and the like..
2406 * The default directory is now /var/db/collectd
2408 2005-07-10, Version 1.1: Minor changes
2409 * Nothing really useful to say ;)
2411 2005-07-09, Version 1.0: Initial Version
2412 * The following modules are provided:
2413 * Load average
2414 * Ping time
2415 * Traffic
2416 * Memory info
