HI Darryl , Thanx , about that here the outbound port 80 is blocked so we cannot wget , moreover this wont solve the problem as to why the the services are getting hung.
Well I had an idea, please critic it. Why not monitor the server.log file if we get some kind of error. We send an alert and then restart the service . Befire that we have to make a repository of types of error that can occur Please do comment Regards Shashank From: Darryl Lewis [mailto:darryl.le...@unsw.edu.au] Sent: Wednesday, September 22, 2010 5:54 PM To: Mendiratta, Shashank; Tomcat Users List Subject: Re: How ot monitor hung tomcat/apache processes? 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" You can then do a wget, and check for that string. Cheers.

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 On 22/09/10 10:03 PM, "Mendiratta, Shashank" <shashank_mendira...@intuit.com> wrote: Hi , I am working on a monitoring system to find out hung tomcat/apache processes . By this I mean if the PID exists and still the apache / tomcat is not responding that due to memory leak or variety of other reasons . Is their a tool to find this . Regards Shashank
