使用java应用程序统计

为了得到memcached服务器的统计，需要使用memcached的stats方法。

示例

import net.spy.memcached.memcachedclient;
public class memcachedjava {
   public static void main(string[] args) {
      //connecting to memcached server on localhost
      memcachedclient mcc = new memcachedclient(new inetsocketaddress("127.0.0.1", 11211));
      system.out.println("connection to server sucessfully");
      system.out.println("stats:"+mcc.stats);
   }
}

输出

当上述程序编译和运行，它提供了以下的输出：

connection to server successfully
stats:[/127.0.0.1:11211:[delete_hits:0, bytes:71, total_items:4, rusage_system:0.2
