I do not believe there is such thing as tomcat mgmt module . It is basically comes down to finding out which metrics matter most to your particular application. Here is the starting guide. He also has book on APM, which I highly recommended.
Thanks for the answer. I can create my own management module and it would be based on what was described in that pdf anyway but I can't help feeling that we are not the first Wily customer to want to monitor Tomcat.
I don't have anything offhand, but wouldn't the performance tuning info from RH be enough? I'm not sure how much of the information changes between the FOSS and RH versions of the software.
