Question

Perl script to monitor application start and stop events in logfile

Perl, Unix

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.

I would recommend SEC. 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 PairWithWindow type rule. Something like this:

 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
 

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

-input=/path/to/logfile 

option for it to follow a certain log.
