-# Plugin to show Postfix statistics - needs pflogsumm
+
-#

-# Contributed by David Obando (david@cryptix.de) - 16.04.2007
+
-#
+=head1 NAME
-#
+
-# Magic markers - optional - used by installation scripts and
+postfix_stats - Munin plugin to monitor postfix statistics.
-# munin-config:
+
-#
+=head1 APPLICABLE SYSTEMS
-#%# family=manual
+
-#%# capabilities=autoconf
+Any system where pflogsumm script can be executed.
+
+=head1 CONFIGURATION
+
+There is no default configuration. This is an example config for Ubuntu:
+
+  [postfix_stats]
+   env.logfiles /var/log/syslog /var/log/syslog.1
+   env.pflogsumm pflogsumm
+
+env.logfiles contains space separated syslog logfiles, usually current log
+and previous log. You can add more log files if you want, but this may 
+increase the time required for analysis.
+
+env.pflogsumm The "pflogsumm" script, can be pflogsumm.pl if it was manually
+downloaded and installed, or "pflogsumm" if it was installed by a package 
+manager (like apt-get).
+
+=head1 INTERPRETATION
+
+This plugin displays the messages: received, delivered, rejected...
+Average per minute is made and it shows the total message count.
+It is useful to know the load and messages being processed.
