The SNMP agent included with vCenter Server can be used to send traps when alarms are triggered on a vCenter Server. The default hardware health alarms send SNMP traps by default.

When an SNMP trap notification occurs, only one trap is triggered and one notification is sent. SNMP Trap Notification Details describes the trap information provided in the body of an SNMP notification.
