Use the DSP Usage Interval Statistics window to view DSP resource usage, per codec, for a series of statistics intervals. To set the statistics time interval and the number of intervals to report, refer to System - Interval Statistics

On the SBC main screen, go to Monitoring > System > Category: System Status and Statistics > DSP Res > DSP Usage Interval Statistics or 

All > System > DSP Res > DSP Usage Interval Statistics

The DSP Usage Interval Statistics window opens.

Figure 1: DSP Usage Interval Statistics


The following output is displayed:

Table 1: DSP Usage Interval Statistics

ParameterDescription
NumberSpecifies a sequence number which identifies the interval for which the set of statistics is shown.
System NameThe node name. 
Interval ValidA 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 will be valid upon meeting the 15-minute time interval. System switch-overs also cause invalid intervals because data is lost during the interval.
  • False
  • True
TimeSystem up time when the interval statistics were collected.

The following statistics appear for each codec.  Statistics are collected once per second.

  • <codec>Peak Used Count – The peak number of resources used for the specified codec since the SBC started up.
  • <codec>Average Used Count – The running average number of used DSP resources for the specified codec since the SBC started up.
  • <codec>Average Avail Count – The running average number of free DSP resources for the specified codec since the SBC started up.

The following codecs appear:

  • G729
  • G726
  • G711Packet 
  • G723
  • Ilbc
  • Evrcb0
  • Amr 
  • Amrwb
  • G722
  • Tone
  • Evrc 
  • G7221 
  • Efr 
  • Opus
  • Silk8 
  • Silk16

NOTEWhen collecting statistics, the following are considered separate codecs:
