Troubleshooting Connectivity Issues

You can test to see if a Remote Services node is reachable with the ping command:

> grbcluster ping --server=server1 --password=pass
Node is not reachable

The latency command provides additional detail:

> grbcluster latency --server=server1 --password=pass
server1 	1.12813ms  0
server2 	1.218103ms 0
This will display the latency from the client machine to each node in the cluster.

Add the --describe flag to see an explanation of each field:

> grbcluster latency --describe
ADDRESS   - Node address
LATENCY   - latency between the local client and a node
NBERR     - Number of errors
