Hi Raja-
Can you please share a little more detail around what you wish to monitor specifically?
For the .NET agent, we have a variety of ways to capture information that may not be captured out of the box, such as defining a custom POCO entry point, for example. Please see docs for more information:
https://docs.appdynamics.com/display/PRO45/.NET+Business+Transaction+Detection
If that doesn't do the trick, we have a good amount of community extensions available to pull in metrics you wouldn't otherwise get with an out of the box agent:
https://www.appdynamics.com/community/exchange/
If you do not see an extension available to meet your needs, you can always build your own extension!

https://docs.appdynamics.com/display/PRO45/Extensions+and+Custom+Metrics
The link above explains extensions more in depth. Please note that all extensions are FREE and do not consume licensing, assuming you are already a paid AppDynamics customer. Also note that you must have a Machine Agent running in your environment as a prerequisite to installing an extension.
