This object displays the system congestion current statistics. On the SBC main screen, go to Monitoring > System > Category: System Status and Statistics > System Congestion Interval Statistics. The System Congestion Interval Statistics window is displayed. The following fields display. By default only ten entries are displayed in a view. You can choose the number of entries to display under the Show entries drop-down box. Click the expand arrow at the top right of the window to display more fields. A setting of 'true' indicates the interval contains valid data during the time interval. Each interval is for a configurable fixed time (default interval is 15 minutes) starting on the hour. For example, if the system starts at 12:05, the first interval at 12:15 will not be valid because it is less than the 15-minute interval. Subsequent intervals are valid upon meeting the 15-minute time interval. System switch-overs also cause invalid intervals because data is lost during the interval. The current high water mark of the total number of active calls in both inbound and outbound directions on all trunk groups in the system for specified interval. This statistic applies to calls which are setting up, tearing down or stable. Switch-over scenario: When a switch-over occurs from SBC-A to SBC-B, the number of stable calls that were transferred from SBC-A to SBC-B equals the initial value of "maxActiveCalls" (immediately after the switch-over). Subsequent values are calculated and recorded accordingly.
