I also wanted to do exactly what you are trying to do. I discovered the only way to do this is with a filter on the appender, instead of being able to set the Level on the appender as you could do with log4j. I don't know yet which method is "better", but the ability to set a filter on the appender does give me the same end-result as with log4j, so I am satisfied with this method.

That doesn't exactly solve what I am trying to do. The problem isn't that I can't get the correct level on a specific logger, the problem is more that I want to have a specific logger go to two different appenders and log at different levels based on the appender. For example I want to have the root logger log at level INFO to the Console. I then want to have the logger for some class Blah log to the appender for root (Console) at the level of root (INFO), but also log to a file Foo.txt at level Debug. So far as I can tell the only way to do this is to set the level of Blah to debug, have a file appender, and also put a filter on the console appender to filter out things below INFO. Does that make sense what I am trying to do? Basically I want a single logger to log to different levels to different appenders.

Hello Eric,
I think this is described in chapter 3 of the manual. See "Example 3.9: Logger level sample (logback-examples/src/main/java/chapter3/ sample4.xml)". The list numbering in that chapter only works with Firefox. So on other browsers you might see all examples numbered as "3.". See also the next section in the same chapter, on "Configuring Appenders", in particular, the cumulative addition of appenders. It might be the other "cleaner" way, you are looking for.
HTH,

So suppose I set my root logger to error, but I want to have another logger operate at debug level. When I do that it makes that loggers level debug for all appenders. For example take the following
<configuration>
<appender name="*FILE*" .... </appender>
<appender name="*STDOUT*" ... </appender>
<logger name="mylogger"> <level value="debug" /> ** <appender-ref ref="FILE" />** </logger>
<root> <level value="error" />* <appender-ref ref="STDOUT" />* </root> </configuration>
In this example mylogger would output at debug level to BOTH STDOUT and FILE. Is it possible to only get mylogger to output at debug level to FILE and error to STDOUT? I realize that I can add a filter to the STDOUT appender to filter anything below ERROR, but I was curious if there was another way to do this, possibly cleaner?
