How fast do you need the graphs updated? How fast are you seeing the graphs updated? > My aim is just to know the number of active threads in tomcat6.

There are a few tools, the best choice depends on exactly what you are trying to do. 1.) You could use JVisualVM. It's a GUI similar to Jconsole, but better. 2.) You could use "top -H". This usually helps when you need to see resource usage by thread. 3.) You could use a profiler like YourKit. This will likely provide the most detail about the threads. 4.) You could use the "jstack" command. This would generate a thread dump, you could then grep that to count the number of threads. Wouldn't recommend doing this too often though, it would affect the performance of your JVM. Might be some other ways too. Hopefully one of these will work though.
