Best Practice - Configure Logging based on Call Trace Criteria

Overview

In a high call volume deployment, the SBC Edge has a new mechanism to turn on logging for a call based on the call criteria you configure; call related messages will appear in the log when enabled by the call trace criteria configured. This new feature provides an alternative to filter based logging on subsystems individually. The following call criteria can be configured for logging:

• Ingress SG
• Remote IP
• Calling Party
• Called Party

The Call Criteria Table, available in the WebUI is used to store the call criteria configuration. 

View the Call Criteria Table

The Call Criteria Table stores the call criteria data configuration; you add call criteria entries in which the the SBC SWe Lite provides call trace messages in the log.

View the Call Criteria table as follows: 

1. In the WebUI, click the Settings tab.

2. In the left navigation pane, go to Logging Configuration > Diagnostic Logging > By Call Criteria.

Perform Call Trace Logging - Configuration Example

Follow the configuration example below for logging based on calls details being traced on the Ingress Signaling group (Ingress SG).

1. In the WebUI, click the Settings tab.

2. In the left navigation pane, go to Logging Configuration > Diagnostic Logging > By Call Criteria. 

3. Add an entry to the Call Criteria Table and set the Rule Type to Ingress SG.
4. Run multiple calls. Calls should be dispersed between the different Signaling Groups. For details on Signaling Groups, refer to Managing Signaling Groups.
5. Access the webui.log ( Diagnostics > Logs > Local System Logs tab). The log displays the log lines associated with the calls using the Ingress SG. For details on the log display, refer to Managing Local Logs.
