Below is an example of some configuration that I use to do the same thing. I hate that there is a requirement in my organization to do this however, it's the wrong way about it if you ask me. For my money, I think you need to strive for log centralization and this represents an effort to decentralize logs. There are a set of tools that I'd recommend using for log centralization. Namely, Logstash backed by Elasticsearch and Kibana. I'd urge you to look at how these tools can help you. <?xml version="1.0" encoding="UTF-8"?>

Dear Troy,
Thanks a lot to help with the appender configurations. I applied the similar configurations and it is working for me now :-)
Now I am trying to get all the 'info' and 'error' level logs in one file(infoLogAppender) and all the 'error' level logs in a sepaate log(errorLogAppender) as well. I tried it using 'LevelFilter' and using 'logger' as well, but it did not work. My configurations looks like:
<property name="logging.log_dir" value="C:/Logs"/> <property name="logging.log_archive_dir" value="C:/Logs/Archive"/> <property name="infoLogName" value="someInfoLog"/> <property name="errorLogName" value="someErrorLog"/> <property name="consoleLogName" value="consoleLog"/>

I get some logs on console as well(mainly JPA related). I want them in a separate log file(consoleAppender). It is also not working.
Could you help here as well? Might be with some example?
