The window configuration item defines the size of the monitoring window and can
range from 1 minute to 15 minutes.
During each window, the SLA parameters are monitored and should a violation be
detected then at the end of the window an alarm will be generated.

rror Threshold
It is recommended to set the error threshold such that at least 2 errors must occur
during the monitor window period to cause an alarm. For example: with a source that
produces one result every second (the default setting for TWAMP or Y.1731) and a
1-minute window, the threshold should be above 3.3% (5% is suggested).
Note: Any or all of the alarm sources may be effectively disabled by setting the
threshold value to 100%.

To counter this problem, the individual traps may be enabled or disabled as shown in
the menu below:
