Solr UI overview

The Solr service provides a web interface where you can view diagnostic and status information, manage collections, configure security, and so on. By default, the web UI is available at http://<host>:8983/solr/#/, where <host> is the ADH host with the Solr Server component installed. You can change the default port number (8983) in the solr.xml Solr configuration section in ADCM. The up-to-date URL(s) of the Solr web UI can be found in ADCM (Clusters<YOUR_CLUSTER>ServicesSolrInfo).

The Solr web UI includes the following sections described below:

Dashboard

This page displays information about the Solr server instance that runs on the given host, including system resource consumption, JVM parameters, and security details.

Security
