I updated the patch basing on your suggestions. You probably can use
the 'walk_directory()' function in other plugins. And it would be
useful to have some standard functions to use in config callback
like boolean entry parser or common ignorelist entry names/parser.
I could send a patch for some cleanups if nobody is working on that,
yet.

ACPI thermal zone plugin for collectd 4.4.1
Here's temperature monitoring plugin using Linux ACPI thermal zone
data from /sys/class/thermal/ or /proc/acpi/thermal_zone/. Since
this is the same source of data, only first directory found is used.
Plugin configuration:
<Plugin thermal>
ForceUseProcfs true # default is false (prefer new sysfs interface)
Device "THRM" # default: no selection (include all devices found)
IgnoreSelected true # default is false
</Plugin>

rrdtool plugin: Put files to the front of the update queue when receiving a flush callback.
wireless plugins: Interpret noise/power values >100 as (dBm + 256).
Hi list,
I currently develop an embedded statistics application and web interface
for OpenWrt Kamikaze based on Collectd and RRDTool.
While working with the wireless plugin I noticed some incompatibilities
with different drivers, namely the Broadcom proprietary driver and madwifi.
/proc/net/wireless on Broadcom:
Inter-| sta-| Quality | Discarded packets | Missed | WE
face | tus | link level noise | nwid crypt frag retry misc | beacon | 18
wl0: 0000 2. 179. 163. 0 0 8040 723 0 0
With the Broadcom proprietary driver you get the actual signal and noise
dbm units by substracting 255 from the values in /proc:
level: 179 - 255 = -76 dBm
noise: 163 - 255 = -92 dBm
/proc/net/wireless on Atheros SoC:
Inter-| sta-| Quality | Discarded packets | Missed | WE
face | tus | link level noise | nwid crypt frag retry misc | beacon | 22
ath0: 0004 21. -73. -94. 21841 0 0 0 0 0
Madwifi writes the actual dBm values into /proc.
So we have (at least for now) three possible types of values:
( x > 0.0 && x <= 100.0 ) current implementation: x is in percent (?)
( x > 100.0 && x <= 255.0 ) broadcom: range intersects with percents but
values below 100.0 (100.0 - 255.0 = -155.0 dBm)
are somewhat unlikely to occur
( x < 0.0 ) atheros: value is already in dBm
A patch which implements the two additional possibilities in collectd's wireless
plugin can be found in the OpenWrt Trac:
https://dev.openwrt.org/browser/packages/utils/collectd/patches/200-wireless-compat.patch
The patch was made against v4.4.0 of collectd but should work with v4.4.1 too.
It would be nice to have this in the next release or so :)

disk plugin: Use correct name under Linux 2.4
Hello everybody.
I have noticed that disk graphs are displayed by collection.cgi as
disk (71687000) instead of the correct disk name on 2.4.x linux
kernels.
The problem seems caused by the fact that the position of disk name of
/proc/partitions (used in 2.4 kernels) differs from /proc/diskstats
(used in 2.6 kernels).
I include as attachment a patch that seems to fix this problem.
I have tested it on 2.4.20 (REDHAT 9) and 2.6.24.4 (Debian Sid) systems.
Thanks a lot for Collectd. It is a _very_ useful program.

network plugin: Don't blindly re-initialize everything in the init callback.
Under Solaris the init functions are called every time the kstat chain
is updated. Since, among other things, send_buffer_fill was set to zero
here, the plugin ``forgot'' about values.

Hello, Collectd.
I wrote a new plugin - notify_email.
This plugin will notify you when threshold conditions are met - one email per
one threshold notify. Email can be sent more then one recipient. Plugin does
this by initiating SMTP session to specified SMTP server (it can also do SMTP
AUTH if needed).
Plugin uses libesmtp library.
Please note:
1. SMTPFrom value sometimes is checked by SMTP server - you
can get failure from SMTP server if you are using not-existent
email.
2. SMTPSubject can contain two '%s' - first for severity and
second for hostname.
3. Hostname used in SMTP connection - is hostname_g, hostname
that is used for all collectd host identification. If it cannot
be resolved by internet DNS - you can expect problems when sending
emails.
Patch and new file are included as attach.

powerdns plugin: Fix some bugs after testing the plugin.
configure.in: Don't use `test -a'.
Some old/weird versions of sh and/or test don't support the `-a' (`and')
argument.

collectd-nagios: Open two different I/O streams for reading and writing.
Full-duplex standard I/O streams are not really supported on sockets.

daemon: Ignore SIGPIPE.
The default action for the PIPE signal is to terminate the process. This
is not really what we want for collectd, as e.g. a client of the unixsock
plugin (which might even be running without root privileges) could kill
the daemon by closing the socket right after sending a request.
The signal now gets ignored and each I/O function is checked for success.
To simply that, the unixsock's output stream is now configured to be line
buffered, removing the need to call fflush() (which could fail as well and
would have to be checked for success).
While I was at it, I renamed the sigaction struct for SIGCHLD to fit the
coding style used elsewhere in collectd.

Add libiptc.
libiptc is not meant to be a public interface by upstream. Debian has thus
removed it from all packages. To be able to use it, we need to take care
of it ourselves.
The configure script now checks, if libiptc is available and uses the
shipped version as a fallback.
The following changes to the libiptc sources were required:
* added copyright headers mentioning the "Netfilter Core Team" as author
* changed libiptc/* includes to * only
* made libiptc.c:standard_target_map() static

collectd.conf(5): Documented the powerdns plugin.
powerdns plugin: Promoted the "not found" message from DEBUG to INFO.
Since users may configure this themselves, they should know when it
doesn't work, so it's not a debug issue anymore.

disk plugin: Use the DATA_MAX_NAME_LEN define for a fixed-sized buffer.
disk plugin: Add support for the statgrab library.
cpu plugin: Add support for the statgrab library.
powerdns plugin: Replace the `Command' option with the `Collect' option.
The original code let the user define the command to use when querying the
server. This commit changes that and lets the user select the _values_ he's
interested in. Depending on whether an authorative server or a recursor is
collected this
- issues a `SHOW *' and manually greps the interesting pieces, or
- builds a command that requests only the interesting values.
Code compiles but it untested. Manpage not yet updated.

powerdns plugin: Added all the other recursor stuff to the lookup table.
src/collectd.h: Check for `_BYTE_ORDER', too.
Apparently Solaris uses that name..

Also added a TODO comment that should be resolved before releasing 4.4.
