RE: Tomcat monitoring scripts
Another simple way is to have start a tomcat once in 2 min using a shell script. If tomcat instance is already running then the ports are in use which prevents the another tomcat instance running. But in this case If the tomcat hangs and the port is in use by other application, there is no means to restart it and monitoring of tomcat is not attached here.

Re: Tomcat monitoring scripts
most people use Perl or shell scripts to do that. There's plenty of scripts on the net for doing that by the process id. sorry, I don't have any links handy. google is your friend. peter On Wed, 12 Jan 2005 15:20:53 +, Edd Dawson [EMAIL PROTECTED] wrote: I'm looking more for something that sits on the actual servers and probes at set intervals and takes remedial action if necessary.. i just wondered if anyone had documented doing such a thing before.

RE: Tomcat monitoring scripts
From: Edd Dawson [mailto:[EMAIL PROTECTED] I'm looking more for something that sits on the actual servers and probes at set intervals and takes remedial action if necessary. One trick that might work and takes almost no effort is to start Tomcat from [x]inetd - if it stops, the next request will restart it (albeit probably slowly). This fails if you have Tomcat listening on multiple ports, or if your Tomcat hangs but doesn't stop. - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
