Perl script to monitor application start and stop events in logfile
Hello,
I am looking for a perl script for Unix that would monitor for a start and stop line in an applciaiton logfile that contains the date/time of stat and stop.
It needs to be able to calculate the date/time from start of applciation for 30 minutes and if no stop is logged to logfile within 30 minutes to send an alert or email notification.
Not a perl scriptor, but Perl is needed for my environment.
Any help appreciated.
Thanks.

Answer Wiki:
I would recommend <a href="http://simple-evcorr.sourceforge.net/">SEC</a>. You can use SEC to monitor the logfile in real time and have it keep track of what you want it to. You would want a <b>PairWithWindow</b> type rule. Something like this:
<pre>
type=PairWithWindow
ptype=RegExp
pattern=MyApplication started
desc=MyApplication started
action=logonly; pipe '$0' /bin/mailx -s 'MyApplication hasn't stopped in 30 minutes' somebody@mydom.com
ptype2=RegExp
pattern2=MyApplication stopped
desc2=MyApplication stopped
action2=none
window=18001
</pre>
That rule will send you an email if the app stop isn't noticed 30 mins after the app start. You would launch sec.pl with the <pre>-input=/path/to/logfile </pre>option for it to follow a certain log.
