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.

Steps

  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 monitors

    system health status show

    Information about the health status of the CIFS-NDO subsystem

    system 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 status

    system health config show -subsystem CIFS-NDO

    The CIFS-NDO alerts that a health monitor can potentially generate

    system health alert definition show -subsystem CIFS-NDO

    CIFS-NDO health monitor policies, which determine when alerts are raised

    system 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
