Thank you so much for the response. i tried for windows it shows the graph, but same way i tried for unix machine, it throws error as below.
Monitor name :UNIX Resources. Cannot initialize the monitoring on 192.168.XX.XX. Error while creating the RPC client. Ensure that the machine can be connected and that it runs the rstat daemon (use rpcinfo utility for this verification). Detailed error: RPC: Failed to create RPC client.
RPC-TCP: Failed to establish RPC server address.
