Low volume postfix_mailqueue munin plugin
|
||
|
|
=========================================
|
||
|
|
|
||
|
|
The original postfix_mailqueue plugin delivered with munin does very well
|
||
|
|
in many aspects. But it has a design related problem: to measure the number
|
||
|
|
of mails per queue (active, incomming, deferred, ...) it counts the entries
|
||
|
|
in the corresponding spool directories every 5 minutes (when munin core asks).
|
||
|
|
If a mail only stays a short time in a queue (especially active and incomming
|
||
|
|
queues) it won't get recognized by postfix_mailqueue.
|
||
|
|
|
||
|
|
Since on my low volume mailserver I'm interested in the total number of sent/
|
||
|
|
recieved messages in the last 5 minutes (for the deferred and hold queues the
|
||
|
|
original method is good enough since a mail there probably stays longer than
|
||
|
|
5 minutes) I changed the behavior and meaning of the "active" and "incomming"
|
||
|
|
graphs to "outgoing" (to the network) and "incomming" (from the network).
|
||
|
|
To determine the number of mails for these graphs the recent (5 minutes, hardcoded)
|
||
|
|
syslog entries are grep'ed for signaling sequences indicating some kind of
|
||
|
|
action of postfix.

-----------
|
||
|
|
|
||
|
|
This little script returns the entries of a (syslog created) file of the last
|
||
|
|
5 minutes.
|

|
|
**You should modify the scripts location in postfix_mailqueue script!**
