Ah okay. Notifications are only sent out, if a status goes to WARNING OR 
CRTITCAL. So you need a plugin which changes its status otherwise you 
won't get a notification. If you don't want a state change in nagios, 
you can still setup a cron job.

It looks like, a cron job in cunjunction with a small shell script 
around check_log2.pl fits your needs much better, than nagios.

Another question: Why is it so important to maintain OK status? Where is 
the problem, if the state changes?
