"By default, Solr will log to the console. This can be convenient when first getting started, but eventually you will want to log to a file. To enable logging, you can just pass a system property to Jetty on startup: java -Djava.util.logging.config.file=etc/logging.properties -jar start.jar This will use Java Util Logging to log to a file based on the config in etc/logging.properties. Logs will be written in the logs directory. It is also possible to setup log4j or other popular logging frameworks."
