Log levels

WebSphere application server lets you define what all logging messages should be logged to the trace.log file.

These are the log levels defined by WAS

• Off: No events are logged.


• Fatal: Task cannot continue and component cannot function.


• Severe: Task cannot continue, but component can still function


• Warning: Potential error or impending error


• Audit: Significant event affecting server state or resources


• Info: General information outlining overall task progress


• Config: Configuration change or status


• Detail: General information detailing subtask progress


• Fine: Trace information - General trace + method entry / exit / return values


• Finer: Trace information - Detailed trace


• Finest: Trace information - A more detailed trace - Includes all the detail that is 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.
