系统:centos 5.x

软件:varnish-3.0.x

ps:3.0以下的版本可以通过Socket连接到Varnish管理端口,通过stat命令查看,3.0以上没有stat命令,只能通过下面的方法解决。

复制代码 代码如下:

$outfile=shell_exec("/usr/bin/varnishstat -x");
$xml=simplexml_load_string($outfile);
echo $xml->getName() . "
";
foreach($xml->children() as $child)
  {
      //$tmpName="";
      foreach($child->children() as $subChild)
      {
        if ($subChild->getName() =="name" )
         {
            $tmpName=$subChild;
        }
        else  if ($subChild->getName() =="value" )
        {
            if ($tmpName!="")
            {
               $arys["$tmpName"]=$subChild;
               $tmpName="";
            }
        }
        else
         {
            continue;
        }
      }
  }
  function byteReduce($bytes)
  {
      if ($bytes>1099511627776)
      {
          return round($bytes/1099511627776)."TB";
      }
      else if ($bytes > 1073741824)
      {
          return round($bytes/1073741824)."GB";
      }
      else if ($bytes>1048576)
      {
          return round($bytes/1048576)."MB";
      }
      else if ($bytes>1024)
      {
          return round($bytes/1024)."KB";
      }
      else
      {
          return $bytes."B";
      }
  }
  echo "client_conn: ".$arys["client_conn"] . "
";
  echo "client_req: ".$arys["client_req"] . "
";
  echo "cache_hit: ".$arys["cache_hit"] . "
";
  echo "cache_miss: ".$arys["cache_miss"] . "
";
  echo "Cache hit rate: ".round(($arys["cache_hit"]/$arys["client_req"])*100)." %
";
  echo "LRU nuked objects: ".$arys[n_lru_nuked]."
";
  echo " ".byteReduce($arys["s_bodybytes"]+$arys["s_hdrbytes"])." Acc Content (".byteReduce($arys["s_hdrbytes"])." header ".byteReduce($arys["s_bodybytes"])." Body)";
?>

效果如下:
