you can monitor the cpu utilization through oem perfomance page.
That's what I would call a pretty easy solution.
You just have to train your application to be able to log into OEM, go to the performance page and look at the data.
Knitty, you are solving a problem poster doesn't have; you have to read the specs.
Prakash, if you are looking for CPU/Memory utilization you might want to setup an O/S level script to periodicallly capture the data you want and put it in whatever place you application might have access to; even a text file would do the trick.
