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.â€�
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.
