Re: Tomcat monitoring

Hi Kevin

Can I suggest 2 options:

1) Write your own monitor (Korn shell script or Perl script) to monitor
the existence of your Tomcat instance: something like

#!/bin/ksh
... insert commands to start Tomcat ...
# poll Tomcat instance, and sleep if its alive
while [`ps -ef | grep $TOMCAT | wc -l` -gt 0 ]
do
        sleep 30 # set wait period in seconds to your taste
done
# otherwise, send an email
mailx -s "Tomcat has died" [email protected] << EOF
        Tomcat just died at `date`
        `tail -100 $TOMCATLOG`
EOF

Where $TOMCAT represents something unique about your Tomcat instance
{command line etc), and $TOMCATLOG is the name of its log file, so the
email can tell you what/why it went belly up.

2) Download a freeware product from Quest called Big Brother, which can
monitor log files for keywords, and/or process instance existence, with
alerts being sent to email, cell phones, SMS etc as required.

Hi,

Does anyone know of any monitoring software for detecting when a tomcat
instance becomes unavailable and notifying support persons via
email/page?
Something open source, preferably.

TIA.
