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>

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

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.

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 :)
Greetings,
JoW

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.
Alessandro

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.
Thank you very much to Eric LeBlanc for debugging this issue.

notify_email plugin: Add plugin to send notifications via email.
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.
