Version 7.2 891 Mediant 500L Gateway & E-SBC
User's Manual 55. Viewing Performance Monitoring
Threshold Crossing Calculation
Threshold based on
Example
Yellow to Green (alarm
cleared)
The change occurs if the measured metric
crosses the configured Minor threshold with
hysteresis.
92 (i.e., 90 + 2)
Note:
• Forwarded calls are not considered in the calculation for ASR and NER.
• If you don't configure thresholds for a specific metric, the device still provides
current performance monitoring values of the metric, but does not raise any
threshold alarms for it.
• You can configure the device to perform certain actions, for example, reject calls
to the IP Group for a user-defined duration, if a threshold is crossed. For more
information, see ''Configuring Quality of Service Rules'' on page 334.
• The section is applicable only to the SBC application.
