Hello, I write a jmx client tool in java, and i use it to monitor tomcat, jboss, jonas ... and i create also user_data_point. Unfortunately, you must have the Templates Bundle license to use it (java template). [Stuart's Reply: Thanks for your comment. I agree that JMX is a much nicer way to monitor a Java app server. Unfortunately, as you noted, it requires an additional license. It would be great if HP would include 1 Java Template vuser (and maybe 1 Microsoft .Net vuser) with each LoadRunner license so that they could be used for monitoring. I have already requested that they enhance the lr_user_data_point function so that people can more easily create monitors for unsupported applications, but perhaps this would be another good feature request.]

For information, you could receive informations from Tomcat in XML format with :
/manager/status?XML=true

Very interesting article. I plan on using this to test a tomcat application now. I am assuming you just configure this script to run with a pacing of 15-30 seconds (or how ever often you want to collect metrics) and then have it run for the length of the scenario?

Thanks for the excellent tip :)

[Stuart's Reply:
Yes, that's the idea. I like to use a pacing interval of 5 seconds, so that I get a fairly high level of granularity.

Note that you will probably have to modify the script a little depending on the number of JVMs, web servers and servlet containers you have configured.

Good luck with your testing!]
