The OpenManageChassis monitor tests the status of a Dell chassis by querying its SNMP agent. The monitor polls the value of the node’s SNMP OID . (MIB-Dell-10892::chassisStatus). If the value is OK (3), the service is considered available.

As this monitor uses SNMP, the queried nodes must have proper SNMP configuration in snmp-config.xml.
