I have you thought about using Simple Event Correlator (SEC)
http://simple-evcorr.sourceforge.net/SEC-tutorial/article.html ?
It monitors single/multiple log files and can react in a variety
of ways. It does regexps and can call shell commands.
Fedora has an RPM.
I use it to send email when a IPSEC VPN is down but only if it
didn't come back up in 15 minutes.
