Shawn Heisey created SOLR-3969:
----------------------------------

             Summary: Admin dashboard -- include cache/buffer memory utilization
                 Key: SOLR-3969
                 URL: https://issues.apache.org/jira/browse/SOLR-3969
             Project: Solr
          Issue Type: Improvement
          Components: web gui
    Affects Versions: 4.0
         Environment: Linux bigindy5 2.6.32-279.9.1.el6.centos.plus.x86_64 #1 SMP Wed Sep
26 03:52:55 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

            Reporter: Shawn Heisey
            Priority: Minor
             Fix For: 4.1


The admin dashboard includes memory utilization, but there is no way on that screen to see
how much memory is being used for cache and buffers -- two additional numbers shown by top.

The most visually appealing way to display this would be to break the Physical Memory graph
into multiple colors, but if that's not practical, more graphs could be added.  I'm not even
sure it's possible, but if it is, it would make a great addition.  Hopefully there would also
be a cross-platform way of doing it so that the major platforms could all be supported.
