This topic describes the method of setting the Solr log4j values. 
  
    To set debug logging levels for SkyVault-Solr components, follow the steps below:
- Copy tomcat/webapps/solr/WEB-INF/classes/log4j.properties to <solrRootDir>/log4j.properties.
- 
        Edit it to add your required logging setting. For example:
        log4j.logger.org.alfresco.solr.tracker.CoreTracker=DEBUG 
- 
        Changes to the log4j.properties file will be re-read by Solr when
          it starts up. If you need to make changes to the logging level while the system is
          running, going to the following URL (either in a browser or for example, using curl)  will
          cause Solr to re-load the properties file. 
        https://<solrHostName>:<solrPort>/solr/admin/cores?action=LOG4J&resource=log4j.properties
