Displaying nondisruptive operation status by using system health monitoring

You can use the system health commands to display information about the overall system health of the cluster and the health of the CIFS-NDO subsystem, to respond to alerts, to configure future alerts, and to display information about how health monitoring is configured.

  1. Monitor health status by performing the appropriate action:
    If you want to display...Enter the command...
    The health status of the system, which reflects the overall status of individual health monitorssystem health status show
    Information about the health status of the CIFS-NDO subsystemsystem health subsystem show -subsystem CIFS-NDO -instance
  2. Display information about how CIFS-NDO alert monitoring is configured by performing the appropriate actions:
    If you want to display information about...Enter the command...
    The configuration and status of the health monitor for the CIFS-NDO subsystem, such as nodes monitored, initialization state, and statussystem health config show -subsystem CIFS-NDO
    The CIFS-NDO alerts that a health monitor can potentially generatesystem health alert definition show -subsystem CIFS-NDO
    CIFS-NDO health monitor policies, which determine when alerts are raisedsystem health policy definition show -monitor node-connect
    Note
    Use the -instance parameter to display detailed information.

Examples​

The following output shows information about the overall health status of the cluster and the CIFS-NDO subsystem:

cluster1::> system health status show
Status
---------------
ok

cluster1::> system health subsystem show -instance -subsystem CIFS-NDO

                   Subsystem: CIFS-NDO
                      Health: ok
        Initialization State: initialized
Number of Outstanding Alerts: 0
 Number of Suppressed Alerts: 0
                        Node: node2
  Subsystem Refresh Interval: 5m

The following output shows detailed information about the configuration and status of the health monitor of the CIFS-NDO subsystem:

cluster1::> system health config show -subsystem CIFS-NDO -instance
