Graphing Apache Web Service Statistics

 - The Apache web server is configured to provided a server status 
   web page that contains a query counter and a byte/megabyte counters.
 - Apache statistics can then be ingested into NRG by using the 
   nrg-apachestat script via http://some.server/server-status url.
 - An examples of Apache statistics graphs can be found at
     http://nrg.hep.wisc.edu/nrg-demo/apache/Ginseng/Ginseng-apache-qs.cgi

Instructions for Graphing Apache Statistics Using nrg-apachestat

 - Configure Apache to serve up server status reports by using
   the Apache configuration strings like the following:
     ExtendedStatus on
     <Location /server-status>
       SetHandler server-status
       order deny,allow
       deny from all
       allow from nrghost.somewhere.com
       allow from 127.0.0.1
     </Location>
 - If you configure Apache to provide server status reports at
   some other location, then edit nrg-apachestat and change the
   $url variable.
 - Add the appropiate .mconf strings to Site.mconf using 
   examples/apache.mconf as your guide.
 - Tell NRG about the new meta target:
     make update
     make notify
