VoIP Performance Manager performance data and processing
Processing of VoIP Performance Manager performance data shows how processes the performance data from . The mechanism that conveys performance data is a trap. The integration procedure is provided in Chapter 3, “Configuring VoIP Performance Manager Integration.�
Processing of performance data

periodically
sends predefined traps to the built-in trap receiver. The built-in trap receiver reads the Integrated Research Enterprise OID (.1.3.6.1.4.1.6102) field of the received traps
and forwards the traps to the
PM Trap Processor.
For each received trap, the PM Trap Processor determines which PM trap handler to invoke based on the name of the trap. The selected PM trap handler parses the trap for performance metrics and applies
their values to the appropriate attributes of the corresponding object in the modeled topology.
With a few exceptions, a predefined
trap contains metrics for just one object.
If the corresponding object cannot be found in the topology, the PM trap handler discards the trap. Media resource type traps are exceptions to this rule. “MediaResourceAggregate objects” on page 26 describes how media resource data is processed.
The traps that convey the performance data should not be confused with threshold traps which are informational traps. Performance data traps provide performance-oriented data for object attributes. Informational traps do not. The collects and parses informational traps, and then the
Adapter Platform
processes them as trap notifications. provides complete information about traps that are converted to notifications.
