Overview
Message logging records Session Initiation Protocol (SIP) and Diameter messages (both requests and responses) received by Converged Application Server. This requires that the logging level be set to at least the INFO level. You can use the message log in a development environment to check how external SIP requests and SIP responses are received. By outputting the distinguishable information of SIP dialogs such as Call-IDs from the application log, and extracting relevant SIP messages from the message log, you can also check SIP invocations from HTTP servlets and so forth.
Note:
The message logging functionality logs all SIP requests and responses; do not enable this feature in a production system. In a production system, you can instead configure one or more logging Servlets, which enable you to specify additional criteria for determining which messages to log. See “Logging SIP Requests and Responses" in Converged Application Server Administrator's Guide.
When you enable message logging, Converged Application Server records log records in the Managed Server log file associated with each engine tier server instance by default. You can optionally log the messages in a separate, dedicated log file, as described in "Configuring Log File Rotation".
