The performance statistics allows you to examine trunk group usage statistics.

These statistics are available on a real time (CURRENT) or on a historical (INTERVAL) basis. By default, the SBC Core maintains four 15-minute intervals of data, so that at any time the previous hour's data is available. However, you may configure the number of intervals and the size of the intervals on the SBC Core.

On the SBC main screen, go to All > System > Interval Statistics. The Interval Statistics window is displayed.

  • equal to or greater than the SBC intervals size, and
  • not less than the SBC interval size multiplied by the SBC number of intervals.

Refer to the RAMP User Guide for configuration details.
