Detailed Description

This is a very simple filter based on LogLevel matching, which can be used to reject messages with LogLevels outside a certain range.

The filter admits three options LogLevelMin, LogLevelMax and AcceptOnMatch.

If the LogLevel of the Logging event is not between Min and Max (inclusive), then DENY is returned.

If the Logging event LogLevel is within the specified range, then if AcceptOnMatch is true, ACCEPT is returned, and if AcceptOnMatch is false, NEUTRAL is returned.

If LogLevelMin is not defined, then there is no minimum acceptable LogLevel (ie a LogLevel is never rejected for being too "low"/unimportant). If LogLevelMax is not defined, then there is no maximum acceptable LogLevel (ie a LogLevel is never rejected for beeing too "high"/important).

Refer to the setThreshold method available to all appenders for a more convenient way to filter out events by LogLevel.
