Log4j different appenders for different log levels using properties file
Solution 1
You need to set the logger to the more detailed of the two levels (DEBUG) but then set a threshold on the appender to tell it to only show messages at INFO and above
log4j.appender.APPENDER_STDOUT.Threshold=INFO
Solution 2
Also, if you want to specify the appender at the package level, you can use:
log4j.logger.[package]=[Level], [Appender]
Example:
log4j.logger.org.apache.cxf=INFO, MyAppender

Since the official documentation for log4j is a broken link, and the getting started guide isn't helping me, I would like to know how to use two appenders with different log levels for the same logger, using a
.properties
file instead of an.xml
one.For example, like this:
log4j.rootLogger=debug, APPENDER_FILE, APPENDER_STDOUT
I'm logging with two different appenders, but on the same log level (
DEBUG
). I would like to use anINFO
log level forAPPENDER_STDOUT
, and aDEBUG
log level forAPPENDER_FILE
.My question is similar to this, but unlike that question, I'm using the
log4j.properties
file, not the xml file.
