Postfix mailqueue monitoring. Alerts when the queue is increasing very fast, or when above the defined thresolds, and not decreasing fast enough.
Client side
Copy bb-postfix.sh in hobboit/xymon ext directory (usually in HOBBITCLIENTHOME/ext)
Xymon user needs to access Postfix's spool directories.
Add the following lines to HOBBITCLIENTHOME/etc/clientlaunch.cfg :
[postfix]
#DISABLED
ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
CMD $HOBBITCLIENTHOME/ext/postfix.sh
LOGFILE $HOBBITCLIENTHOME/logs/postfix.log
INTERVAL 5m
Server side
Add the “postfix” tag for appropriated hosts in HOBBITSERVERHOME/etc/bb-hosts, for example :
123.234.123.234 toto # postfix
To graph the vaues, follow the usual procedure :
In hobbitserver.cfg, add postfix to TEST2RRD and GRAPHS definitions and add :
SPLITNCV_postfix="*:GAUGE"
In hobbitgraph.cfg, add the following :
[postfix]
FNPATTERN postfix,(.*).rrd
TITLE Postfix statistics

# Simple Postfix spool watcher plugin for big brother (testet with 18b3)
# Just copy this script on the mailhost running postfix to
# $BBHOME/ext
# and change in the file $BBHOME/etc/bbdefs.sh the variable
# BBEXT from "<whatisalreadyinthere>" to "<whatisalreadyinthere> postfix.sh"
# Perhaps you have something to change below.
