  • The following alerts are seen in the event logs:

[Node-01: cshmd: hm.alert.raised:alert]: Alert Id = ClusterSwitchConnectivity_Alert , Alerting Resource = Node-01 raised by monitor ethernet-switch
[Node-01: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: ClusterSwitchConnectivity_Alert[Node-01].

  • The output of system health alert show shows the below details:

    Indication Time: Sat Feb 17 02:00:36 2024
           Suppress: false
