A.3 Logging Levels
The following table outlines the logging levels that the Common Logging component supports.
Table A-1 Logging Levels
| Severity(Log Level) | Usage |
|---|---|
| Fatal | Irrecoverableprogram, process, and thread errors that cause the application to terminate. |
| Warning | Recoverableerrors that may still enable the application to continue running but should be investigated (for example, failed user sessions or missing data fields). |
| Notice(default) | High-level,informational messaging that highlights progress of an application (for example, startup and shutdown of a process or session, or user login and logout). |
| Diagnostic | Fine-graineddiagnostic errors—used for viewing processing status, performance statistics, SQL statements, etc. |
| Trace | Diagnosticerrors—use only for debugging purposes as this level enables all logging levels and may impact performance. |
The configuration file specifies enabling of priorities in a hierarchical fashion. That is, if Diagnostic is active, the system enables the Notice, Warning, and Fatal levels.
