Hi,
This weekend a MySQL server which backends a couple of postfix servers went down for a couple of hours without anyone noticing and I'm looking to setup some monitoring so that it doesn't go unnoticed again in future. I thought a good start would be a look though the syslogs for entries with a priority of critical but I found nothing. If i searched for warnings and found the messages I was looking for (warning: proxy:mysql:/usr/local/etc/postfix/mysql/mynetworks.cf: table lookup problem) but I also found a lot of mesages I wasn't interested in.. eg.. warning: Illegal address syntax from unknown[186.136.28.57] in MAIL command: <"Microsoft Outlook" <no-re...@fibertel.com.ar>> warning: hostname outboundmail1.contractsfinder.businesslink.gov.uk does not resolve to address 5.79.34.51 etc So I have two questions. 1) Is it right that a 'table lookup problem' is only a warning and not a critical event? In my setup I would feel it was a critical event and I would guess it would be in most peoples setups if they've gone to the trouble of using a SQL backend. 2) Is there any way to make a 'table lookup problem' syslog as critial for my setup ?
