Re: How to detect down of tomcat.
Hi, Darryl. I understood that Tomcat cannot output specific words when tomcat terminated abnormally. I will write a servlet that outputs specific words. I will write a script to call it periodically. The script outputs error log when specific words are not output. Thank you very much. - Original Message - From: Darryl Lewis darryl.le...@unsw.edu.au To: Tomcat Users List users@tomcat.apache.org; Tomcat Users List users@tomcat.apache.org Sent: Sunday, March 20, 2011 8:20 PM Subject: Re: How to detect down of tomcat. The other problem will be that tomcat is running, but the application is not responding. There may be nothing in the logs for this, and this is one of my most common issues. In this case, I use some custom scripts to simulate a log in and check for an expected string in the return.
