Hi, the manager application can return values in XML. You just need to hit:-
http://localhost:8080/manager/status?XML=true or wherever it's located. This makes it a bit easier to write shell scripts based on Free Heap or Max Threads or whatever. I've got a perl script which checks whatever values you need and logs them to a .csv for easy reporting. I'll make it a bit better and post it if anyone has any interest.
