Thanks for asking your question on the community. I wanted to let you know that since your first post contained a significant amount of code, it was flagged for spam. I cleared that up for you and your post is now live. I'm doing some searching to see if I can find any helpful existing content to share with you.
I've also reached out to the Apple CSM for you, so you could also be hearing directly from them.
I have tried again installation on new VM. I did all steps as mentioned. I am able to see the Custom Metric/Linux Monitor folder under the VM on AppD dashboard. But under mountedNFSStatus i am not getting any data. Sharing below snapshot.
Also i am getting nullpointer exception in machine agent logs.

In call we were, tried installation on new VM and was stucked at mvn build step as internet connectivity wasn't there on VM. Today, I have resolved that one issue and completed all remaining of the steps as per documentation. But observing issue as mentioned above in detail. I'll require further assistance to resolve it.

Hello Shubham,
In addition to Ryan suggestion, I'm posting more useful links for your ref if incase those may help.
Please note AppDynamics moved extensions under an open-source model, to enable customers to directly evolve them to suit their needs / build new use cases, you can find more information
https://docs.appdynamics.com/display/PAA/Support+Advisory%3A+Changes+to+Extensions+Support+Model
We have also documented answers to most common extension queries along with troubleshooting tips and tricks in the following links.
