Thanks, I find the below segment from log4j manual
----Note that filtering is only supported by the DOMConfigurator. The
PropertyConfigurator does not support filters.
That's a reason for me to migrate from log4j.properties to log4j.xml.

Setting Threshold=ERROR can force log4j to log the higher priority loggings
of ERROR & FATAL, as demonstrated by Adrian Janssen said below.
But I'm wondering to know if there's a way to log only ERROR loggings, no
FATAL in one appender. That is, one appender to log only one level; not to
log one level and its higher levels.

actually there is some filtering ability available in the normal properties
file, probably enough for you needs:
log4j.appender.MyAppender.Threshold=INFO

Eureka! I have a solution! I now have my logging messages split out into the
4 types that I support: DEBUG, INFO, WARN & ERROR. My app-debug.log file
contains everything, down to my app-error.log file which only contains
errors!
Why is it that these moments tend to occur after midnight... :-)
Note: I switched from log4j.properties to log4j.xml in order to take
advantage of filters, which aren't supported in the properties file.
Here's my log4j.xml file, enjoy:

Subject: log4j.properties - How to parse outpu to multiple files
Greetings log4j list!
I'd like my logging output to be sent to multiple files at once. However, I
only want ERRORs in the app-error.log file, DEBUG in the app-debug.log file,
etc. As a potential compromise, I would be OK if I was able to at least
reduce the types of log messages as the severity increased.
Can anyone assist with my log4.properties file? I've included a copy below,
but note that this config sends all the logging output to all files.
In addition, is there a way to avoid all the duplication in this config
file, so I just have to change the name of the output file in each case, and
inherit all the RollingFileAppender settings as I define each file?
Thanks!
