There are several health monitors that monitor different parts of a cluster. Health monitors help you to recover from errors within ONTAP systems by detecting events, sending alerts to you, and deleting events as they clear.
| Health monitor name (identifier) | Subsystem name (identifier) | Purpose | ||
|---|---|---|---|---|
Cluster switch(cluster-switch) |
Switch (Switch-Health) |
Monitors cluster network switches and management network switches for temperature, utilization, interface configuration, redundancy (cluster network switches only), and fan and power supply operation. The cluster switch health monitor communicates with switches through SNMP. SNMPv2c is the default setting.

Node connectivity(node-connect) |
CIFS nondisruptive operations (CIFS-NDO) |
Monitors SMB connections for nondisruptive operations to Hyper-V applications. |
||
Storage (SAS-connect) |
Monitors shelves, disks, and adapters at the node level for appropriate paths and connections. |
