Monit monitor service
In case the Tomcat service halts or hangs due to whatever... , I installed monit to restart the service and then alert me. See an example of my config below, added to the bottom of the /etc/monit/monitrc file.
dspace@ir1:/etc/monit$ sudo cat /etc/monit/monitrc
set daemon 60
set logfile syslog facility log_daemon
set mailserver localhost
set mail-format { from: monit@ez.sun.ac.za }
set alert root@localhost
set httpd port 2812
allow %username%:%password%
check process sshd with pidfile /var/run/sshd.pid
start = "/usr/sbin/service ssh start"
stop = "/usr/sbin/service ssh stop"
if failed port 22 protocol ssh with timeout 5 seconds then restart
alert hgibson@sun.ac.za
check process tomcat6 with pidfile /var/run/tomcat6.pid
start = "/usr/sbin/service tomcat6 restart"
stop = "/usr/sbin/service tomcat6 stop"
if failed port 80 protocol http with timeout 300 seconds then restart
alert hgibson@sun.ac.za
alert wklap@sun.ac.za
