After the initial discovery and modeling of the network, IP Performance Manager continuously monitors the status of the discovered systems using:
Internet Control Message Protocol (ICMP) polling
Simple Network Management Protocol (SNMP) polling
IP Performance Manager also processes SNMP trap messages received from the network to obtain status information for the discovered systems.
The VMware Smart Assurance IP Manager Reference Guide provides information about the MIBs polled and SNMP traps processed by the IP Performance Manager.
