RE: How to detect down of tomcat.
Hi Darryl. I need a script that do the same you mention: For myself, I have scripts that detects when the service is down, sends me an email, then tries to restart it, then will email if it has managed to recover it. If it can't restart it after 5 minutes, then I get an SMS. Can you share it?

Request processors are all tied up waiting on some lock 3. A connector has failed and is no longer accepting connections These are all situations where a Tomcat restart may be in order but the check the process list technique will fail to detect them. We have a status page that checks the health of our server and we use wget in a script to check the data that comes back.

Right. And many other things like that.

Re: How to detect down of tomcat.
Hi, Darryl. Thanks for your advice. My explanation seems to have been bad. I explain it a little more. It is a method to output the information of the abnormal termination in catalina.log that I want to know. Would you teach it if you know some method?
