A.2 Logging Levels
This topic outlines the logging levels that the Common Logging component supports.
Table A-1 Logging Levels
Severity (Log Level) | Usage |
---|---|
Warning | Recoverable errors that may still enable the application to continue running but should be investigated , such as failed user sessions or missing data fields). |
Notice (default) | High-level, informational messaging that highlights progress of an application , such as startup and shutdown of a process or session, or user login and logout. |
Diagnostic | Fine-grained diagnostic errors—used for viewing processing status, performance statistics, SQL statements, etc. |
Trace | Diagnostic errors—use only for debugging purposes as this level enables all logging levels and may impact performance. |
Fatal | Irrecoverable program, process, and thread errors that cause the application to terminate. |
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.
