There are several health monitors that monitor different parts of a cluster.
|Health monitor name (identifier)||Subsystem name (identifier)||Purpose|
|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.|
|CIFS nondisruptive operations (CIFS-NDO)||Monitors SMB connections to ensure nondisruptive operations to Hyper-V applications.|
|Storage (SAS-connect)||Monitors shelves, disks, and adapters at the node level to ensure that they have appropriate paths and connections.|
|System||not applicable||Aggregates information from other health monitors.|
|Storage (SAS-connect)||Monitors shelves at the cluster level to ensure that all shelves always have appropriate paths to two HA clustered nodes.|
