Viewing JVM logs

The Java virtual machine (JVM) logs are written as plain text files.

About this task

Use either of two techniques to view the JVM logs for an application server:
  • Use the administrative console, which also supports viewing the JVM logs from a remote machine.
  • Use a text editor on the machine where the logs are stored.
New feature New feature: This topic references one or more of the application server log files. Beginning in WebSphere Application Server Version 8.0 you can configure the server to use the High Performance Extensible Logging (HPEL) log and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files or native z/OS logging facilities. If you are using HPEL, you can access all of your log and trace information using the LogViewer command-line tool from your server profile bin directory. See the information about using HPEL to troubleshoot applications for more information on using HPEL.newfeat
