Log Levels

Applications may log information under different categories referred to as levels. There are six levels: INFO, NOTE, WARN, ERROR, DEBUG and TRACE. The levels may all be enabled or disabled individually except for the ERROR level, which is always enabled.

• ERROR - A log entry that is made under the ERROR level is obviously important to react to. Log entries in this level are marked as errors in the management pages.

• WARN - Similar to the ERROR level, the WARN level is marked as warnings in the management pages. Warnings are less critical than errors but should still be investigated.

• INFO and NOTE - The INFO and the NOTE level represent general information and information that is slightly more noteworthy than general information but still not a warning.

• DEBUG and TRACE - The two remaining levels, DEBUG and TRACE, are not enabled by default but may be enabled in order to get more fine-grained information. This may be useful in a situation where you are trying to find out the cause of a problem.
