The X over time is a new one, it's been mentioned a couple times today, and I can certainly account for it.

We use a few syslog analyzers (using syslog-ng as a transport), some with simple logcheck, other with database for rules and hosts; and every time problem is the same - writing rules is 90% of the problem.

Or saying _single PCI ERROR on Solaris - ignore, 10 in a straight line - send warning...
