Just a note.
When Tomcat crashes, is the pid still there?
Would it not be better to monitor the port?
See below
####
bibboek@ir1:/etc/monit$ sudo cat monitrc
set daemon 60
set logfile syslog facility log_daemon
set mailserver localhost
set mail-format { from: [email protected] }
set alert root@localhost
set httpd port 2812
allow XXXXX:XXXXX
check process sshd with pidfile /var/run/sshd.pid
start program "/etc/init.d/ssh start"
stop program "/etc/init.d/ssh stop"
if failed port 22 protocol ssh then restart
check host sunscholar with address scholar.sun.ac.za
start program = "/etc/init.d/tomcat6 restart"
stop program = "/etc/init.d/tomcat6 stop"
if failed port 80 proto http then restart
alert [email protected]
alert [email protected]
