Understanding threshold groups and settings

VoIP Availability Manager monitors the network by sending SNMP polls and by processing SNMP traps, and by processing information from the VoIP Performance Manager. The results of the polling and trap processing are then compared to threshold values that define acceptable and unacceptable levels of availability. The polling and trap processing results, in conjunction with the status updates received from IP Availability Manager, are used to diagnose the failed objects that interrupt network service connectivity.

VoIP Availability Manager uses settings to assign polling and threshold parameters to groups of managed objects. From a polling and threshold perspective, a setting is a collection of parameters common to a particular type of analysis (for example, network services polling).

Using the Polling and Thresholds Console, you can customize SNMP polling result thresholds—and SNMP trap processing result thresholds—for VoIP Availability Manager by modifying default threshold groups or by creating new threshold groups.
