The call audit logging feature provides a summary of SIS decisions during a call, such as the trigger and composition selected and services invoked. Below is an overview of SIS audit levels, information collected by the audit, instructions for using audit logging, and some examples.

Audit logging levels

The SIS currently supports the following audit levels:

Level Information logged 
ALL

every call received from the network

 
COMPONENT

selected components only

 
NONE

(no information)

Component settings

You can enable auditing for individual compositions, address subscriptions, service key descriptions, and trigger addresses.

Tip
Initial settings, changes, and default

  • You can specify initial audit settings, that apply when a composition is installed or when a subscription is created.

  • Changes to component audit settings can be made at any time, and take immediate effect.

  • The default component audit setting, if unspecified, is disabled.
Warning
Changes only apply to new calls

The SIS determines the audit level for the lifetime of a call during initial request processing. Any changes to audit settings apply only to new calls (those subsequently triggered in the SIS).

Collected information

An individual call audit log contains the network dialog identifier, parameters of the initial request, and any of the following optional information, depending on call processing:

Information Log details

if initial processing aborted

for example, due to insufficient license capacity or the initial request missing a required parameter

Outcome of trigger processing

subscription profile located

search key and name of profile

trigger matched and successfully found a composition

trigger’s component identifier

composition selected

composition’s component identifier

trigger matched and its failure clause invoked

trigger’s component identifier

no triggers matched

Outcome of composition evaluation

entry and exit from the script input and output interceptors (if present)

the name of the service reference of a composition service that becomes eligible for invocation

entry and exit from composition service input and output interceptors (if present)

the name of the extension reference of an extension component that is invoked by an interceptor

if the composition service invocation failed

reason for failure (for example, service response timeout, local service not active)

if the extension component invocation failed

reason for failure (for example, service response timeout)

if IN FurnishChargingInformation data from a composition service is discarded after initial acceptance due to the interaction policy in force

the name of the service reference for the service that generated the discarded FCI data

composition completed normally

composition halted by a script or service instruction
Tip
Initial request processing only

The audit log only reports on initial request processing — the decisions made during trigger processing and composition evaluation. It does not include any information about processing of events later in the call.

Using audit logging

To use the SIS audit logging features:

  1. Enable audit logging in the SIS. WARNING: This is required for the SIS to check any other audit logging settings.

  2. Reload the SIS configuration, for the configuration change to take effect.

  3. If the COMPONENT audit level is selected, configure audit settings for compositions or other entities in the SIS (such as subscriptions).

The SIS outputs one audit record log message:

  • for each call for which audit logging is enabled (either explicitly or implicitly)

  • using the SLEE Tracer named "audit", for the SIS instance at the Info trace level

  • to the Rhino console log (by default) using the log key trace.<SIS instance name>.audit.

You can capture audit records several ways, including: by registering a trace notification listener with the SLEE to capture the audit trace messages from the SIS, or by creating a Rhino logging configuration that channels the audit log messages to a separate log file.
