Enabling performance logging

You can enable performance logging using the administrative console of the application server.

1. Open WebSphere® Application Server admin console.
2. Select Troubleshooting > Logs and Trace
3. Choose a server.
4. Change the log detail levels by expanding the Components and Groups section and locating com.ibm.mdm.mds.log.PerformanceLog.
5. Select either the Configuration tab or the Runtime tab to make your changes.
   • If you select the Configuration tab: your log detail change will be permanent unless you manually change them. This choice requires a restart of the MDM operational server.
   • If you select the Runtime tab, then the log detail changes are immediately in effect and are only temporary. Be aware that upon a restart of the operational server, the detail settings default to the original settings.
6. Set the class logger for com.ibm.mdm.mds.log.PerformanceLog to ALL.
7. Save your changes.
8. If you want to change the default location for the performance log output, follow these steps.
   1. From the WebSphere Application Server admin console, go to Servers > Server Types > Websphere application servers > SERVER_NAME > Java and Process Management > Process Definition > Java Virtual Machine.
   2. Select Custom Properties.
   3. Add a new property in the following format.

      mad.log.dir=/filesystem/newdirectory/

      Make sure that you include the slash (/) at the end of the directory path.
   4. Save to your master configuration.
