You can manage the log levels for JBI components from this page. You can either load the default logging level by selecting the Load Defaults button or set a specific log level using the drop down list.
Some JBI components provide several loggers while other components might not provide any. However, there will always be a logger level displayed for the entire component. But the logger level setting will only have an effect if a component implements its loggers based on the default name. The provider of a JBI component might provide additional documentation on specifying logging levels.
Note - The logging levels for JBI components are often inherited from a parent logger such as the JBI logger. To view and set parent logging levels, under Common Tasks, select Application Server. Then in the Application Server panel, select Logging and then Log Levels. Look for the drop down list for the JBI module to view and set the parent JBI logging level.
