Here a example how to configure filters. Note: Filters are only available if
you use xml configuration.
<appender name="CONSOLE.OUT" class="org.apache.log4j.ConsoleAppender">
<param name="target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{HH:mm:ss.SSS} (%6r) %-5p
[%-7t] %F:%L %x - %m%n"/>
</layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMin" value="debug"/>
<param name="LevelMax" value="info"/>
<param name="AcceptOnMatch" value="false"/>
</filter>
<filter class="ch.ergonomics.pms.common.supervision.TraceDenyFilter"/>
<filter class="ch.ergonomics.pms.common.supervision.XMLDenyFilter"/>
</appender>
This appender has three filters attached. The first is a log4j built in filter
(LevelRangeFilter), the thow others are self written filters, derived from
org.apache.log4j.spi.Filter which filter LogEvents based on some values in MDC.
If a LogEvent reaches an appender, it is presented to the attached filters in
the order they are configured. The Filter results in:
- ACCEPT the LogEvent is accepted, no more further Filters are asked
- DENY the Log Event is rejected, no more further Filters are asked
- NEUTRAL next filter in chain is asked
within a self written Filter you can implement any logic you want.
