Configuring temporary log levels for specific nodes

The log levels can be configured temporarily for specific loggers in a given node. This makes it possible to get detailed logs for a specific theme handled by that node or module 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 new nodes that are started.

  1. Access the Grid Management Pages as a user with the grid-admin role, and select Nodes.
  2. Select Log Levels from the details of the relevant node.
  3. The Log levels page displays the application name and modules for the selected node.
  4. Click the application name, or module name to display all loggers.
  5. Identify the relevant loggers using the logger filter.
  6. Select the check boxes for the relevant loggers to change the logging. Log level changes are immediately applied.
  7. When the required events have been captured in the logs, click the Reset icon. This resets the log level configuration to the corresponding property values, for all loggers for this node. Resetting the log levels is especially important for log levels Debug and Trace, which can have a serious impact on performance.
