Solr features a Web interface that makes it easy for Solr administrators and programmers to view <<files-screen.adoc#files-screen,Solr configuration>> details, run <<query-screen.adoc#query-screen,queries and analyze>> document fields in order to fine-tune a Solr configuration and access <<getting-assistance.adoc#getting-assistance,online documentation>> and other help.

== Dashboard
Accessing the URL `\http://hostname:8983/solr/` will show the main dashboard, which is divided into two parts.
A left-side of the screen is a menu under the Solr logo that provides the navigation through the screens of the UI. The first set of links are for system-level information and configuration and provide access to <<logging.adoc#logging,Logging>>, <<collections-core-admin.adoc#collections-core-admin,Collection/Core Administration>>, and <<java-properties.adoc#java-properties,Java Properties>>, among other things. At the end of this information is at least one pulldown listing Solr cores configured for this instance. On <<solrcloud.adoc#solrcloud,SolrCloud>> nodes, an additional pulldown list shows all collections in this cluster. Clicking on a collection or core name shows secondary menus of information for the specified collection or core, such as a <<schema-browser-screen.adoc#schema-browser-screen,Schema Browser>>, <<files-screen.adoc#files-screen,Config Files>>, <<plugins-stats-screen.adoc#plugins-stats-screen,Plugins & Statistics>>, and an ability to perform <<query-screen.adoc#query-screen,Queries>> on indexed data.

The center of the screen shows the detail of the option selected. This may include a sub-navigation for the option or text or graphical representation of the requested data. See the sections in this guide for each screen for more details.

====
The path to the Solr Admin UI given above is `\http://hostname:port/solr`, which redirects to `\http://hostname:port/solr/\#/` in the current version. A convenience redirect is also supported, so simply accessing the Admin UI at `\http://hostname:port/` will also redirect to `\http://hostname:port/solr/#/`.

== Login Screen
If authentication has been enabled, Solr will present a login screen to unauthenticated users before allowing them further access to the Admin UI.
.Login Screen
image::images/overview-of-the-solr-admin-ui/login.png[]
This login screen currently only works with Basic Authentication.
See the section <<basic-authentication-plugin.adoc#basic-authentication-plugin,Basic Authentication Plugin>> for
details on how to configure Solr to use this method of authentication.
If Kerberos is enabled and the user has a valid ticket, the login screen will be skipped.
However, if the user does not have a valid ticket, they will see a message that they need to obtain a valid ticket before continuing.
