Viewing RTP statistics thresholds
The RTP statistics application uses a system of thresholds to evaluate levels of QoS during
RTP sessions. The thresholds are configured on several QoS metrics. Your configuration of
the thresholds determines when the application evaluates a session as having bad QoS
conditions.
This section describes the thresholds that you can configure, how you can view the thresholds
that are currently configured, and the metrics on which you can configure them.
The RTP statistics application samples the VoIP engine every RTCP interval, which is
configured in Avaya Aura
Period". The RTCP interval is typically 5 to 8 seconds. For information about configuring the
RTCP interval (RTCP report period), see Administrator Guide for Avaya Aura
Manager.

About this task
A threshold on a metric: For example, you can configure a threshold on the metric 'packet
loss'. The application samples the metric every RTP interval and increments a counter (event
counter) if the sampled value is over the threshold. Hence, the 'event-counter' represents the
number of times the metric was sampled over its threshold.
An event threshold: An event threshold is a threshold on an event counter. If QoS traps are
configured, the application generates a QoS trap when, at the end of a session, one or more
event counters are over their event thresholds. For example, if the event threshold for packet
loss is 2, the application generates a QoS trap if packet loss is sampled over its threshold two
or more times.
Thresholds on metric averages: The application calculates averages of some of the metrics.
When an RTP session terminates, the application evaluates the average metrics and
generates a QoS trap (if QoS traps are configured) if one of them is over its corresponding
threshold.
