This would be "standard":
<Configuration status="warn">
<Appenders>
<File name="debug-appender" fileName="debug.log">
<PatternLayout pattern="%d %p %c{1.} [%t] %m%n" />
</File>
<File name="info-appender" fileName="info.log">
<PatternLayout pattern="%d %p %c{1.} [%t] %m%n" />
</File>
</Appenders>
<File name="error-appender" fileName="error.log">
<PatternLayout pattern="%d %p %c{1.} [%t] %m%n" />
</File>
<Loggers>
<Root>
<AppenderRef ref="debug-appender" level="trace" />
<AppenderRef ref="info-appender" level="info" />
<AppenderRef ref="error-appender" level="warn" />
</Root>
</Loggers>
</Configuration>
This results in:
- debug.log - gets trace, debug, info, warn, error, fatal messages
- info.log - gets info, warn, error, fatal messages
- error.log - gets warn, error, fatal messages
If I understand correctly, you want
- debug.log - should ONLY get trace and debug, no other level messages
- info.log - should ONLY get info level messages (no warn, error, fatal)
- error.log - is fine as defined above
To achieve this, you need to apply filtering in addition to the config
above.
The filters that Alexey pointed out look good.
You use these filters by placing them inside the configuration for the
appender that you want to filter.
For example:
<Configuration status="warn">
<Appenders>
<File name="debug-appender" fileName="debug.log">
<PatternLayout pattern="%d %p %c{1.} [%t] %m%n" />
<Filters>
<ThresholdFilter level="info" onMatch="DENY" onMismatch="NEUTRAL"/>
<ThresholdFilter level="warn" onMatch="DENY"
onMismatch="NEUTRAL"/>
<ThresholdFilter level="error" onMatch="DENY"
onMismatch="NEUTRAL"/>
<ThresholdFilter level="fatal" onMatch="DENY"
onMismatch="NEUTRAL"/>
<ThresholdFilter level="debug" onMatch="ACCEPT" onMismatch="DENY"/>
</Filters>
</File>
