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
