Managing trace settings

Add or modify workload and system trace settings to troubleshoot and resolve problems with the system.

About this task

You can view and download the following log files: error.log and trace.log. Each log file has a maximum size and a file limit, which defines the number of versions of that file that can be maintained on the system:
  • Each error.log file can be a maximum of 2 MB and up to five versions of the file are maintained for a total of 10 MB of available data.
  • Each trace.log file can be a maximum of 100 MB and up to 20 versions of the file are maintained (1 active file and 19 archived files).
If a version of either log file is older than 30 days, it is automatically deleted.

A set of default classes is defined as the trace string to include in the logs. You can modify the level of trace for these classes and added new classes. The trace levels that are provided are based on Java™ Logging convention and WebSphere® Application Server levels.

Procedure

  1. Log in to the console as the Workload resources administrator with full permissions.

    • To modify the level of an existing trace setting, click the current level, select a new one from the list, and click Save. The trace levels are described in the following list:
      OFF
      No events are logged.

      Potential error or impending error.
      INFO

      FINEST
      Trace information: A more detailed trace, which includes all the details that are needed to debug problems.
      ALL
      All events are logged. If you create custom levels, ALL includes your custom levels and can provide a more detailed trace than FINEST.
