Monitoring NFS on Linux Clients

For monitoring NFS clients on Linux, the eG Enterprise offers the NFS Linux Client monitoring model.

Each layer of the model is mapped to tests that monitor the RPC calls made by the target NFS client to a server and promptly detect abnormalities in the RPC communication. Using the metrics so reported, administrators can find quick and easy answers for the following performance questions:

  • Is the NFS client available over the network?
  • Is the client utilizing the CPU, memory, and disk space resources optimally?
  • Is the client overloading the server with too many RPC requests?
  • Are too many RPC requests getting retransmitted to the server?
  • Are the remote file systems available?
  • Is the client taking too long to access the remote file systems?
  • Is any NFS-mounted directory unavailable?
  • Is any NFS-mounted directory consuming too much space?
