Couple quick log4j questions

[lowlyintern]

First, if the threshold for an appender has been set and assigned to the rootLogger, is it possible to set the level of the same appender to a descendant with a lower level? For instance:

log4j.logger.com.mikel.smart.metrics.envfilters.SeaState=DEBUG, A1
log4j.additivity.com.mikel.smart.metrics.envfilters.SeaState=False

If appender A1 has threshold set to INFO, it will write to the appender but the level will be INFO instead of DEBUG.

Second, after additivity has been set to false, is it possible to add multiple appenders back to a descendant with different threshold levels? For example, I know:

log4j.logger.com.mikel.smart.metrics.envfilters.SeaState=WARN, A1, A2

Will add both A1 and A2 to the SeaState class at the WARN level, but what if I want A1 at DEBUG and A2 at WARN?

I don't understand what you are asking for the first question, it is possible to have the root logger be set to level INFO by default and have an individual package be at DEBUG level, the messages should show up in the output as DEBUG. ?


For different levels to more than one appender, I know this is possible in logback with the use of filters Chapter 6: Filters

Where I have something written to two appenders and within each appender i have logic to only show if it of the specified level. this is to create separate error.log and debug.log files.

But sorry, I don't know how to do this in log4j
