IBM service log settings
To configure service logs:Administrative console | Troubleshooting | Logs and Trace | server | IBM Service Logs
Enable service log Specifies creation of a log file by the IBM Service log. File Name Name of the file used by the IBM Service log. Maximum File Size Maximum size in megabytes of the service log file. Default value is 2 megabytes.
When this size is reached, the service log wraps in place. Note that the service log does not roll over to a new log file like the JVM logs.
Message Filtering Set message filter level to suppress some message categories. Applied to all logs, not just the service log.
Enable Correlation ID Specifies the generation of a correlation ID that is logged with each message.
Use the correlation ID to correlate activity to a particular client request, or correlate activities on multiple appservers.
