Hi there,
I've just integrated OpenBSD-support into the tcpconns module. Please test this
thouroughly, it's not running for so long on my box (but works fine).
Also, please add -lkvm to the right place in the autoconf-stuff so that when
using tcpconns on OpenBSD, libkvm is linked.
Also, I'm not sure about how much of the license we need to embed. I'll
therefore post the full license information so you can put it in if you feel
like:

Developers,
I am writing an updated ebuild for gentoo and I made this patch that allows
ip_vs.h to be located and the ipvs module to build. Normally I would include
this with the ebuild, but I thought it may be beneficial to send it to you.
Please review it and let me know what you think. I am still inexperienced with

applying it or a similar patch, please let me know so I can adjust the ebuild

bindings/perl/Collectd.pm: Improved the way access to @plugins is synchronized.
So far, a lock has been placed on @plugins, so that no two threads could
access the list of plugins simultaneously. This could cause problems which in
certain situations could even lead to deadlocks. E.g. when using the perl
plugin in combination with the rrdtool plugin with debugging enabled one would
get hit by the following situation: the perl plugin holds the lock on @plugins
and then dispatches values to the rrdtool plugin from some Perl plugin's read
function. The rrdtool plugin then tries to acquire its cache lock. At the same
time some other plugin dispatches values to the rrdtool plugin as well and
this thread now holds the lock on the rrdtool cache. While holding that lock,
the rrdtool plugin might dispatch a debug logging message and thus calls the
perl plugin's log-callback which tries to get the lock on @plugins thus
causing a deadlock.
This has been resolved by the following two changes:
* Restrict the lock to the list of plugins of one type. This allows to access
e.g. read and log plugins in parallel.
* Unlock the variable before calling the Perl callback function. This
further prevents nested locks.

postgresql plugin: Added a plugin to collect PostgreSQL database statistics.
This plugin collects active server connections, transaction numbers, block IO
and table row manipulations of PostgreSQL databases. For this purpose it keeps
persistent connections to all configured databases. The statistics are
collected from PostgreSQL's "statistics collector" subsystem.
Currently, statistics are collected from the pg_stat_database,
pg_stat_user_tables and pg_statio_user_tables views. The following new types
have been introduced: pg_blks, pg_n_tup_c, pg_n_tup_g, pg_numbackends, pg_scan
and pg_xact. The type names are basically the same as the column names in the
queried views to keep things consistent. For the number of tuples, counter and
gauge values exist, so the type names have been prefixed with "_c" and "_g"
respectively.
Sample plugin configuration:
<Plugin postgresql>
<Database foo>
Host "hostname"
Port "5432"
User "username"
Password "secret"
SSLMode "prefer"
KRBSrvName "kerberos_service_name"
</Database>
<Database bar>
Service "service_name"
</Database>

This plugin collects active server connections, transaction numbers, block IO
and table row manipulations of PostgreSQL databases. For this purpose it keeps
persistent connections to all configured databases. The statistics are
collected from PostgreSQL's "statistics collector" subsystem.
Currently, statistics are collected from the pg_stat_database,
pg_stat_user_tables and pg_statio_user_tables views. The following new types
have been introduced: pg_blks, pg_n_tup_c, pg_n_tup_g, pg_numbackends, pg_scan
and pg_xact. The type names are basically the same as the column names in the
queried views to keep things consistent. For the number of tuples, counter and
gauge values exist, so the type names have been prefixed with "_c" and "_g"
respectively.
Sample plugin configuration:
<Plugin postgresql>
<Database foo>
Host "hostname"
Port "5432"
User "username"
Password "secret"
SSLMode "prefer"
KRBSrvName "kerberos_service_name"
</Database>
<Database bar>
Service "service_name"
</Database>
</Plugin>

src/utils_complain: Changed c_release() into a macro.
While the c_complain*() functions are usually used in error conditions only,
c_release() is usually used whenever things went right (which should be the
more common case ;-)). In order to minimize the overhead in the latter case,
c_release() has been changed into a macro which checks if the complaint
actually has to be released and calls c_do_release() in that case. This
function then takes care of reporting the release-message (this is the
original implementation of c_release()). So, we remove the overhead of a
function call in the usual case, i.e. when we don't have to report any
messages.

src/plugin.c: Initialize plugins before checking if read callbacks are available.
plugin_init_all() checks if any read callbacks are available before starting
the read threads. A few plugins register their read callback from their
init callback though. By initializing the plugins before that the read
threads are still started correctly if all plugins register the read
callback in the init callback.

Hello.
Here is my first collectd plugin.
It shows the two values of qmail queues, messages and todo.
The latter should be zero in normal cases. I included it because it
may help diagnose problems.
Maybe a config parameter could be added for it.
It supports a parameter for the Qmail base directory:
<Plugin qmail_queue>
QmailDir "/var/qmail"
</Plugin>
Feel free to modify it if you need.

Use -Wall -Werror (AM_CFLAGS) when building any module.
A few plugins have to set custom CFLAGS. When using "<plugin>_la_CFLAGS =",
$(AM_CFLAGS) will no longer be used when compiling <plugin> as that resets the
CFLAGS to the empty string. So, in that case, we have to explicitly add
$(AM_CFLAGS) to the custom CFLAGS of that plugin.
After doing so, a couple of problems have been identified which have been
fixed in this patch as well. That includes a possible SEGFAULT in the snmp
plugin which was missing an argument to WARNING().
