Hi Ayush, is there a problem you're running into with the ntservice probe? Is it not picking up services?
You'll need to make sure that you follow the probe's requirements and the Support Matrix that shows compatible systems.
You might also want to check out the cluster probe. It can monitor Microsoft, RedHat, HP-UX service guard, and Veritas clusters. I'm not sure what you're looking to monitor, but that might be another option. See the metrics available from the probe here.
Hope that helps!
