  • system health subsystem show

    Display the health of subsystems

    Availability: This command is available to cluster administrators at the admin privilege level.

    Description

    The system health subsystem show command displays the health status of each subsystem for which health monitoring is available. This command aggregates subsystem health status from each node in the cluster. A subsystem’s health status changes to "degraded" when a health monitor raises an alert. You can use the system health alert show command to display information about generated alerts.

    Parameters

    { [-fields <fieldname>,…​]

    If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

    | [-instance ] }

    If you specify the -instance parameter, the command displays detailed information about all fields.

    [-subsystem <hm_subsystem>] - Subsystem

    Selects the specified subsystem.

    [-health {ok|ok-with-suppressed|degraded|unreachable|unknown}] - Health

    Selects subsystems that have the specified health status.

    [-init-state {Invalid|Initailizing|Initialized|Starting_Discovery|Starting_Re-Discovery|Discovery_Done_Partially|Discovery_Done}] - Initialization State

    Selects subsystems that have the specified initialization state.

    [-outstanding-alert-count <integer>] - Number of Outstanding Alerts

    Selects subsystems that have the specified number of outstanding alerts.

    [-suppressed-alert-count <integer>] - Number of Suppressed Alerts

    Selects subsystems that have the specified number of suppressed alerts.

    [-node {<nodename>|local}] - Node

    Selects subsystems for the specified node.

    [-refresh-interval <[<integer>h][<integer>m][<integer>s]>,…​] - Subsystem Refresh Interval

    The refresh interval is in minutes. A value of zero disables the sub-system refresh until a reboot or restart of the subsystem process.

    Examples

    The example below displays the health status of each subsystem:

    cluster1::> system health subsystem show
    Subsystem         Health
    ----------------- ------------------
    SAS-connect       degraded
    Switch-Health     OK
    CIFS-NDO          OK

    The example below displays detailed information about the health status of each subsystem:

    cluster1::> system health subsystem show -instance
    
                                 Subsystem: SAS-connect
                                    Health: degraded
                      Initialization State: initialized
              Number of Outstanding Alerts: 0
               Number of Suppressed Alerts: 0
                                      Node: node1,node2
                Subsystem Refresh Interval: 30m, 30m
    Subsystem: Switch-Health
                                    Health: ok
                      Initialization State: initialized
              Number of Outstanding Alerts: 0
               Number of Suppressed Alerts: 0
                                      Node: node1
                Subsystem Refresh Interval: 5m
    Subsystem: CIFS-NDO
                                    Health: OK
                      Initialization State: initialized
              Number of Outstanding Alerts: 0
               Number of Suppressed Alerts: 0
                                      Node: node1
                Subsystem Refresh Interval: 5m
