> A properly running Solr server with a very clean configuration may have absolutely no messages logged at WARN or ERROR.  When this happens, clicking on the logging tab produces a screen with no messages and a spinning cursor, which looks like the page is hung.
> It has come to my attention that there is a "No events available" message already in the UI, but it doesn't work.  I can think of two ways to fix the problem:
>  * Fix the detection in the UI so that the "No events available" message actually works.  Also, the spinner could be removed.  The spinner is a big reason that the page looks broken.
>  * Solr could log a "startup complete" message at WARN so that there is always something to display.
