Solr uses http://logging.apache.org/log4j/2.x/[Log4J version
{ivy-log4j-version}] for logging which is configured using
`server/resources/log4j2.xml`.
Take a moment to inspect the contents of the `log4j2.xml` file so that you are
familiar with its structure.
+
By default, Solr log messages will be written to `SOLR_LOGS_DIR/solr.log`.
+The format of the log messages can be changed by
https://logging.apache.org/log4j/2.x/manual/layouts.html#PatternLayout[modifying
the pattern] used in the `<PatternLayout/>`, or by changing the layout
implementation -- e.g., a
https://logging.apache.org/log4j/2.x/manual/json-template-layout.html[`<JsonTemplateLayout/>`]
can be used to configure JSON formatted log files.
When you're ready to deploy Solr in production, set the variable
`SOLR_LOGS_DIR` to the location where you want Solr to write log files, such as
`/var/solr/logs`.
You may also want to tweak `log4j2.xml`.
