Overview

Note

The command parameters described in this article are available only on SBC SWe/Cloud deployments.

For each Trunk Group, the SBC provides separate performance and memory counters for INVITEs and NON-INVITE cases for SIP responses (2xx,3xx,4xx,5xx,6xx). The counters compute the Call Set-up Success Rate (CSSR) for each Trunk Group.

The parameter sipCssrStats is available under SIP Trunk Group.

Note

The following corresponding statistics are available under addressContext zone (displayed as output of appropriate show <table | status> commands):

  • sipTrunkGroupCSSRCurrentStatistics
  • sipTrunkGroupCSSRIntervalStatistics.

You can write the CSSR Interval Statistics sipTrunkGroupCSSRIntervalStatistics on a file by enabling under system fileStatisticsAdmin.

Command Syntax

For an existing SIP Trunk Group, the syntax to disable/enable collection of CSSR statistics are as follows:

% set addressContext <acName> zone <zoneName> id <zoneId> sipTrunkGroup <tgName> sipCssrStats <disabled | enabled>

Once enabled, the following commands display the CSSR statistics collected by the SBC:

  • CSSR Current Statistics:

    % show <status | table> addressContext  <acName> zone <zoneName> sipTrunkGroupCSSRCurrentStatistics <tgName> <CSSR counter>

  • CSSR Interval Statistics:

    % show <status | table> addressContext  <acName> zone <zoneName> sipTrunkGroupCSSRIntervalStatistics <tgName> <CSSR counter>
Note

If you do not provide the Trunk Group name and a specific CSSR counter, all possible counters are displayed, resulting in a long and truncated output.


To write the output of the show command for the interval statistics in a .csv file, use the following syntax:

% set system fileStatisticsAdmin sipTrunkGroupCSSRIntervalStatistics state <disabled | enabled>
Note

For each Trunk Group, the SBC creates a separate .csv file.

Configuration Examples

To enable collection of SIP CSSR Statistics for an existing SIP Trunk Group, use the following example:

% set addressContext default zone defaultSigZone id 1 sipTrunkGroup test_sip_tg sipCssrStats enabled
% commit


To display the SIP CSSR Current Statistics, use the following example:

> show status addressContext default zone defaultSigZone sipTrunkGroupCSSRCurrentStatistics

Note

The output of show table command is similar to the show status command illustrated above, but in a tabular format.

The output of the SIP CSSR interval statistics are similar to that of the current statistics, but represents an aggregate over a period of time.


To write the SIP CSSR Interval Statistics to .csv files, use the following example:

% set system fileStatisticsAdmin sipTrunkGroupCSSRIntervalStatistics state enabled
% commit
Note

For each Trunk Group, the SBC creates a separate .csv file.

This statistics sipTrunkGroupCSSRIntervalStatistics is available only on SBC SWe/Cloud deployments.
