Configuring temporary log levels grid-wide

The log levels can be configured temporarily for specific loggers in a running grid. This makes it possible to get detailed logs for a specific theme handled by applications, nodes, modules or loggers, while avoiding filling the logs with unnecessary noise. During troubleshooting it is useful to increase the log levels on a detailed level. The changed log levels can be reset to the property values used for all nodes.

  1. Access the Grid Management Pages as user with the grid-admin role, and select Monitoring > Log Levels. The left panel displays all the applications and modules currently running in the grid.
  2. Click the applicable application or module to display the individual loggers. You can also select All to display loggers for all applications and modules.
  3. Identify the relevant loggers, for example by specifying the name in the logger filter.
  4. Select the check boxes corresponding to the applications, module or loggers to change the logging. Log level changes are immediately applied.
  5. When the required events have been captured in the logs, click the Restart icon. This resets the log level configuration to the corresponding property values, for all loggers. Resetting the log levels is especially important for log levels Debug and Trace, which can have serious impact on performance.
