OpenVZ Cacti templates

[GoogleCodeExporter]

This is a feature request for graphs for OpenVZ using
/proc/user_beancounters ... full docs are at
http://wiki.openvz.org/Proc/user_beancounters.  So far, I've only seen some
weak graphs.

Is anyone willing to pay for it?  It'll be a couple hours of work.

Sample PHP code to parse /proc/user_beancounters and get into a nice array:

<?php

   $cmd = "cat /proc/user_beancounters";
   $str = `$cmd`;

   $result = array();

   foreach ( explode("\n", $str) as $line ) {
      if (!preg_match("/^\s+uid/",$line) && 
           preg_match("/[0-9]/",$line) && 
          !preg_match("/^\s+dummy/i",$line) && 
          !preg_match("/^Version/",$line)) {
         // kmemsize is a special case
         if(preg_match("/^\s+[0-9]/",$line)) {
            $words = preg_split('/\s+/', $line);
            $result['kmemsize_held']    = $words[3];
            $result['kmemsize_maxheld'] = $words[4];
            $result['kmemsize_barrier'] = $words[5];
            $result['kmemsize_limit']   = $words[6];
            $result['kmemsize_failcnt'] = $words[7];
         } else {
            // The rest are sane
            $words = preg_split('/\s+/', $line);

            $result[$words[1]."_held"] = $words[2]; 
            $result[$words[1]."_maxheld"] = $words[3]; 
            $result[$words[1]."_barrier"] = $words[4]; 
            $result[$words[1]."_limit"] = $words[5]; 
            $result[$words[1]."_failcnt"] = $words[6]; 
         }
      }
   }

   print_r($result);

?>

Ryan, can you attach the file as an attachment?  It's mangled.
