Use this page to configure and manage log level settings.
Using log levels you can control which events are processed by Java logging. When you change the level for a logger, the change is propagated to the children of the logger.
Enter a log detail level that specifies the components, packages, or groups to trace. The log detail level string must conform to the specific grammar described below. You can enter the log detail level string directly, or generate it using the graphical trace interface.
If you select the configuration tab, a list of well-known components, packages, and groups is displayed. This list might not be exhaustive.
If you select the runtime tab, the list of components, packages, and groups is displayed will all such components currently registered on the running server. This list is static; you will not see your application logger names on the runtime tab.
<component> = <level>
where <component> is the component for which to set a log detail level, and <level> is one of the valid logger levels (off, fatal, severe, warning, audit, info, config, detail, fine, finer, finest, all). Separate multiple log detail level specifications with colons (:).
Version 6 Logging Level | Logging Level pre-Version 6 | Trace Level pre-Version 6 | Content / Significance |
Off | Off | All disabled* | Logging is turned off. * In Version 6, a trace level of All disabled will turn off trace, but will not turn off logging. Logging will be enabled from the Info level. |
Fatal | Fatal | - | Task cannot continue and component/ application/ server cannot function. |
Severe | Error | - | Task cannot continue but component/ application/ server can still function. This level can also indicate an impending fatal error. |
Warning | Warning | - | Potential error or impending error. This level can also indicate a progressive failure (for example, the potential leaking of resources). |
Audit | Audit | - | Significant event affecting server state or resources |
Info | Info | - | General information outlining overall task progress |
Config | - | - | Configuration change or status |
Detail | - | - | General information detailing subtask progress |
Fine | - | Event | Trace information - General trace + method entry / exit / return values |
Finer | - | Entry/Exit | Trace information - Detailed trace |
Finest | - | Debug | Trace information - A more detailed trace that includes all the detail that is needed to debug problems |
All | All enabled | All events are logged. If you create custom levels, "All" would include those levels, and could provide a more detailed trace than "finest". |
