Listing Cluster Nodes

Thenodescommand provides a list of nodes in the cluster, along with status information. This command is a shortcut for thenode listcommand. For example:

> grbcluster nodes ID ADDRESS STATUS TYPE LICENSE PROCESSING #Q #R JL IDLE %MEM %CPU b7d037db server1:61000 ALIVE COMPUTE VALID ACCEPTING 0 0 10 19m 15.30 5.64 735c595f server2:61000 ALIVE COMPUTE VALID ACCEPTING 0 0 10 19m 10.45 8.01

Add the—describeflag to see an explanation of each field:
