DESCRIPTION
Like many Web-Applications in the past, the Solr Admin UI up until 4.0 was entirely server based. It used separate code on the server to generate their Dashboards, Overviews and Statistics. All that code had to be maintained and still ... you weren't really able to use that kind of data for the things you needed it for. It was wrapped into HTML, most of the time difficult to extract and changed the structure from time to time w/o announcement. After a short look back, we're going to look into the current state of the Solr Admin UI - a client-side application, running completely in your browser. We'll see how it works, where it gets its data from and how you can get the very same data and wire that into your own custom applications, dashboards and/oder monitoring systems.
