::> system health alert show
        Node: Node1
      Alert ID: CriticalCECCCountMemErrAlert
      Resource: DIMM-16
      Severity: Critical
   Indication Time: Wed Jan 10 16:45:18 2024
      Suppress: false
     Acknowledge: false
   Probable Cause: The DIMM has degraded, leading to memory errors.
  Possible Effect: Memory issues can lead to a catastrophic system panic,
           which can lead to data downtime on the node.
 Corrective Actions: 1. Contact technical support to obtain a new DIMM of the same specification.
           2. If possible, perform a takeover of this node and bring the node down for maintenance.
           3. Refer to the DIMM replacement guide for your given hardware platform to replace the DIMM.
           4. Bring the storage system online.
