Defines the Minor threshold (in percentage) of the selected
performance monitoring metric, which is the lower threshold located
between the Yellow and Green states.
To consider a threshold crossing:
■ Increase in severity (i.e., Green to Yellow): Only this value is
used.
■ Decrease in severity (Red to Green, or Yellow to Green): This
value is used with the hysteresis, configured by the 'Hysteresis'
parameter (see below).
The valid range is 0 to 100. The default is 0.
Defines the Major threshold (in percentage) of the selected
performance monitoring metric, which is the upper threshold located
between the Yellow and Red states.
To consider a threshold crossing:
■ Increase in severity (i.e., Yellow to Red, or Green to Red):
Only this value is used.
■ Decrease in severity (Red to Yellow): This value is used with
the hysteresis, configured by the 'Hysteresis' parameter (see
below).
The valid range is 0 to 100. The default is 0.
Defines the amount of fluctuation (hysteresis) from the configured
threshold in order for the threshold to be considered as crossed.
Hysteresis is used to avoid false reports being sent by the device.
Hysteresis is used only when the severity level decreases (i.e., from
Red to Yellow, Yellow to Green, or Red to Green).
The valid value is 0 to 15 (in percentage). The default is 5.
For example, if you configure the 'Major Threshold' parameter to 70%
and the 'Hysteresis' parameter to 2%, the device considers a
threshold crossing from Red to Yellow only if the ASR crosses 72%
(i.e., 70% + 2%).
Defines the minimum number of call sessions (sample) that is
required for the device to calculate the performance monitoring
metrics (per window size). If the number of call sessions is less than
the configured value, no calculation is done.
The default is 10 calls.
Note: The calculation also depends on the configured sampling
window size (see 'Window Size' parameter). For example, if the
parameter is configured to 10 calls, but only 5 calls were processed
during the configured sampling window, no calculation is done.
Defines the time interval (in minutes) during which the device
calculates the performance monitoring metrics. For example, if the
parameter is configured to five minutes, the calculation is done for the
last five minutes.
The default is 5 minutes.
