IBM service log settings

Use this page to configure the IBM® service log, also known as the activity log.

Supported configurations: You can only access this page when the server is configured to use basic log and trace mode.

To view this administrative console page, click Troubleshooting > Logs and Trace > server_name > IBM Service Logs.

Use this page to configure the IBM service log, also known as the activity log. The IBM service log contains both the WebSphere® Application Server messages that are written to the System.out stream and some special messages that contain extended service information that can be important when analyzing problems. There is one service log for all WebSphere Application Server Java™ virtual machines (JVMs) on a node, including all application servers and their node agent (if present). A separate activity log is created for a deployment manager in its own logs directory. The IBM Service log is maintained in a binary format. Use the Log and Trace Analyzer or Showlog tool to view the IBM service log.

Enable service log

Specifies creation of a log file by the IBM Service log.

File Name

Specifies the name of the file used by the IBM Service log.

Maximum File Size

Specifies the maximum size in megabytes of the service log file. The 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.

Enable Correlation ID

Specifies the generation of a correlation ID that is logged with each message.

You can use the correlation ID to correlate activity to a particular client request.

You can also use it to correlate activities on multiple application servers, if applicable.
