Subject Tomcat JMX Monitoring - Busy Threads?
Date Thu, 03 Mar 2011 21:29:52 GMT
I'm trying to monitor Tomcat 6.0.29 using JMX. Specifically, I want to
monitor the number of active threads servicing requests so I can get
an alert if it approaches the maximum. While I have JMX monitoring
working in general, I can't seem to get the number of threads.
Everything I have read suggests looking at:


And examining the currentThreadsBusy attribute. Unfortunately, I only
ever seem to get -1 as a value. I've tried it on five different Tomcat
instances and I always get -1.

Is there something I'm missing? Should I be looking at a different value?
