Monitoring clustered watch with the mmwatch status command

Use this information to monitor clustered watch with the mmwatch status command.

To see the statuses for all of the current watches, use the mmwatch all status command:

# mmwatch all status
Device                      Watch ID            Watch State
gpfs0                       CLW1553608557       Active
          
Node Name                                       Status
node1.ibm.com                                   HEALTHY
node2.ibm.com                                   HEALTHY
node3.ibm.com                                   HEALTHY
node4.ibm.com                                   HEALTHY

To get a more verbose status for a specific watch ID, use the mmwatch gpfs0 status --watch-id <watchID> -v command:

# mmwatch gpfs0 status --watch-id CLW1553608557 -v
