How to monitor an NFS file system Mounted RHEL7 system using AppDynamics?

Hi All,

 

How to monitor an NFS file system Mounted RHEL7 system using appdynamics?

I have tried using monitoring NFS using  "AppDynamics Extension for Linux Monitoring"

I have configured based on the documentation but unfortunately, I do not see the NFS share

using  machineagent-4.4.3.1214.

 

I am getting the following error:

[Monitor-Task-Thread3] 23 Aug 2019 12:50:21,893 ERROR NFSMountMetricsTask - Exception occurred collecting NFS I/O metrics
