The IP Availability Manager and IP Performance Manager uses the Internet Control Message Protocol (ICMP) and Simple Network Management Protocol (SNMP) polling to monitor the IP network. The results of this polling are then compared to threshold values that define acceptable and unacceptable levels of connectivity or performance. The thresholds, in conjunction with traps, are used to diagnose the failed or degraded objects that interrupt network connectivity or adversely affect network performance.

The monitoring of the network is controlled by ICMP and SNMP polling-related and threshold-related settings that are created for the IP Availability Manager through the Polling and Thresholds Console.

This discussion focuses on the polling-related settings. Threshold related settings are described in the VMware Smart Assurance IP Manager User Guide.
