I suggest that you also use the Tomcat Management App - it provides some useful statistics and information on request Threads.

JAMon can monitor servlet/jsp performance as well as sql performance and it is open source. In fact I just created 3 short videos that explain it and put them on youtube. They are a few minutes long each. Even if you have used JAMon before I suggest watching them as it can do more than most people know.

* JAMon 101 - Intro to Monitoring with JAMon -
* JAMon reports demo - This shows the type of statistics that are gathered for servlets/jsp's as well as sql and more -
* Operating System monitoring - This is a new feature that will be in the next release that lets you monitor your linux/unix/mac scripts with JAMon. -

Here is a link that explains how to install jamon in tomcat.

I'll paste the steps for tomcat 6 here.

Tomcat 6
* Put jamon-2.7.jar (or higher) in the tomcat 'lib' directory.
* Put jamon.war (or higher) in the tomcat 'webapps' directory.
* Add the following Valve line to Tomcat's server.xml file. The 'Engine' line is used to show context.

For further details go to - a fast, free open source performance tuning api.
