## NAME
    [Log::Log4perl::Filter::LevelRange](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3AFilter%3A%3ALevelRange/markdown) - Filter for a range of log levels

## SYNOPSIS
        log4perl.filter.Match1               = [Log::Log4perl::Filter::LevelRange](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3AFilter%3A%3ALevelRange/markdown)
        log4perl.filter.Match1.LevelMin      = INFO
        log4perl.filter.Match1.LevelMax      = ERROR
        log4perl.filter.Match1.AcceptOnMatch = true

## DESCRIPTION
    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").
