Log::Log4perl::Filter::LevelRange - Filter for a range of log levels


    log4perl.filter.Match1               = Log::Log4perl::Filter::LevelRange
    log4perl.filter.Match1.LevelMin      = INFO
    log4perl.filter.Match1.LevelMax      = ERROR
    log4perl.filter.Match1.AcceptOnMatch = true


This Log4perl custom filter checks if the current message has a priority matching a predefined range. The LevelMin and LevelMax parameters define the levels (choose from DEBUG, INFO, WARN, ERROR, FATAL) marking the window of allowed messages priorities.

LevelMin defaults to DEBUG, and LevelMax to FATAL.

The additional parameter AcceptOnMatch defines if the filter is supposed to pass or block the message (true or false).
