Re: Solr 4.4 with log4j and multiple indexes on tomcat 6
Hi Russ, It's not really indexes that lit, but Solr running in Tomcat, so I don't think there's a way...

I'm using solr 4.4 and I've copied jcl-over-slf4j-1.6.6.jar, jul-to-slf4j-1.6.6.jar, log4j-1.2.16.jar, slf4j-api-1.6.6.jar and slf4j-log4j12-1.6.6.jar into my tomcats lib/ directory.

My only solution is to add the 4 jar files to each of the solr webapps in their tomcat/webapps/solr_webapp/WEB-INF/lib directory and then the webapp will pick up it's logging.properties file. Does anyone have a solution where I don't need to add the 4 jars to each of the solr webapps but still get a log file per index.

Although your solution might let you log each webapp to its own file, you are incurring extra overhead by running each index in its own full Solr install. One Solr install can handle thousands of separate indexes - we call them cores. Most of the important parts of Solr will log the core name with the request. I'm in the process of trying to improve that so *everything* will include the core name in the log. See SOLR-5277. When that work is complete, it may even be possible to get those logs in separate files by switching logging implementations or writing some a custom log4j appender. Side issue: logging.properties is the configuration file used by java.util.logging ... but the jar files you have mentioned will set Solr up to use log4j. The config file for that is typically log4j.properties or log4j.xml. Thanks, Shawn
