RPC Ports Test

An NFS server listens on many TCP/UDP ports for RPC requests from clients. If too many RPC calls to the server fails, it could be because the TCP/UDP port configured for communication between the client and server is unavailable. This test periodically checks the NFS server for the availability of user-configured ports and promptly alerts administrators if one/more ports are found to be unavailable.

Target of the test : NFS on Linux server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every port specification.

Configurable parameters for the test
