What is file descriptor count in Solr admin UI?
<p>I have installed solr 5.2.1 on my linux server. In the UI admin screen under dashboard section, am having a file descriptor count, which is displaying some values to me. So can anyone explain me please what is this file descriptor count. </p>

<p>This is coming only in Linux box, i have installed the same version of solr on windows environment also, but there in the UI screen the file descriptor count is not shown. Is this only  specific to Linux/Unix box?</p>

<p>Thanks
