The <<overview-of-the-solr-admin-ui.adoc#overview-of-the-solr-admin-ui,Overview of the Solr Admin UI>> explains the basic features of the user interface, what's on the initial Admin UI page, and how to configure the interface. In addition, there are pages describing each screen of the Admin UI:

* *<<logging.adoc#logging,Logging>>* shows recent messages logged by this Solr node and provides a way to change logging levels for specific classes.
