Listing Cluster Nodes

The nodes command provides a list of nodes in the cluster, along with status information. This command is a shortcut for the node list command. 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 --describe flag to see an explanation of each field:

> grbcluster nodes --describe

PROCESSING- Processing state (ACCEPTING, DRAINING, STOPPED)
#Q        - Number of jobs in queue
#R        - Number of jobs running
JL        - Job Limit (maximum number of running jobs)
IDLE      - Idle time since the last job execution (in minutes)
%MEM      - Percentage of memory currently used on the machine
%CPU      - Percentage of CPU currently used on the machine
STARTED   - Node start time, use --long
RUNTIMES  - Deployed runtime versions, use --long
