How do folks monitor the health of their postfix installations?
log monitoring seems to be essential, rates of warning/error messages
seem meaningful. Then there are the statistics regularly emitted, but
these seem more indicative of busyness.
Finally, monitoring queue sizes is probably advisable. Am I better off
looking at the filesystem directly or using "postqueue -j"? postqueue
offers additional details, but I'm wondering about the overhead over just
looking at counts.
Generally we use simple script that calls this for every postfix instance
and count lines:
postmulti -x postqueue -j|wc -l
most of the time it's enough, but if you use different instances for
incoming/outgoing mail, it may make sense to monitor them separately.
