That's not a good idea. What happens if the entire system crashes...you won't
get any data/alerts. End to end uses another machine to monitor the first.

In my experience, the PID can still exist of tomcat but a Java heap crash has
stopped it responding.
Checking a PID will not check if the application is responding.
You're better to do some sort of end to end monitoring

It depends on the application you are running, but a simple test would
be to access the webpage (ensuring part of it is served from Tomcat, not
apache) and check for an expected response.
For example, a simple jsp page that prints out ok

Hi ,
I am working on a monitoring system to find out hung tomcat/apache

Instead of looking for problems so you can restart the JVM, trying

1) Automatic restarts on OutOfMemory errors:
Add the following to CATALINA_OPTS:
-XX:OnOutOfMemoryError=/usr/sbin/restart_tcserver
Write your restart_tcserver (you may send an e-mail notification from it
etc.)
2) This is what
