ps ax | grep tomcat is not very helpful - sometimes the Tomcat process is running but Tomcat doesn't respond. So my "watch" script: I check selected URL directly using wget <URL> and examine the downloaded document for certain content (simple regexp matching). If it doesn't match then I try to download and check it again. If it doesn't match again then I restart Tomcat.
The script "watch" is executed via cron every 2 minutes. And if restart is needed I'm informed via e-mail. Just for information - this kind of restart is raised once or twice a week.
