Memcached stats 命令用于返回服务器统计信息，如PID，版本，连接等.
语法
Memcached stats 命令的基本语法如下所示 :
stats
示例
statsSTAT pid 1162STAT uptime 5022STAT time 1415208270STAT version 1.4.14STAT libevent 2.0.19-stableSTAT pointer_size 64STAT rusage_user 0.096006STAT rusage_system 0.152009STAT curr_connections 5STAT total_connections 6STAT connection_structures 6STAT reserved_fds 20STAT cmd_get 6STAT cmd_set 4STAT cmd_flush 0STAT cmd_touch 0STAT get_hits 4STAT get_misses 2STAT delete_misses 1STAT delete_hits 1STAT incr_misses 2STAT incr_hits 1STAT decr_misses 0STAT decr_hits 1STAT cas_misses 0STAT cas_hits 0STAT cas_badval 0STAT touch_hits 0STAT touch_misses 0STAT auth_cmds 0STAT auth_errors 0STAT bytes_read 262STAT bytes_written 313STAT limit_maxbytes 67108864STAT accepting_conns 1STAT listen_disabled_num 0STAT threads 4STAT conn_yields 0STAT hash_power_level 16STAT hash_bytes 524288STAT hash_is_expanding 0STAT expired_unfetched 1STAT evicted_unfetched 0STAT bytes 142STAT curr_items 2STAT total_items 6STAT evictions 0STAT reclaimed 1END
使用Java应用程序的统计数据
要从Memcached服务器获取统计信息，您需要使用Memcached 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 successful"); System.out.println("Stats:"+mcc.stats); }}输出
在编译和执行程序时，你会到达请参阅以下输出 :
Connection to server successfulStats:[/127.0.0.1:11211:[delete_hits:0, bytes:71, total_items:4,rusage_system:0.220013, touch_misses:0, cmd_touch:0, listen_disabled_num:0,auth_errors:0, evictions:0, version:1.4.14, pointer_size:64, time:1417279366,incr_hits:1, threads:4, expired_unfetched:0, limit_maxbytes:67108864,hash_is_expanding:0, bytes_read:170, curr_connections:8, get_misses:1,reclaimed:0, bytes_written:225, hash_power_level:16, connection_structures:9,cas_hits:0, delete_misses:0, total_connections:11, rusage_user:0.356022,cmd_flush:0, libevent:2.0.19-stable, uptime:12015, reserved_fds:20,touch_hits:0, cas_badval:0, pid:1138, get_hits:2, curr_items:1, cas_misses:0,accepting_conns:1, evicted_unfetched:0, cmd_get:3, cmd_set:2, auth_cmds:0,incr_misses:1, hash_bytes:524288, decr_misses:1, decr_hits:1, conn_yields:0]]
