查询实时的状态，类似于“top”命令。
在命令行下执行任一命令（第二个办法需要通过php）：
- 使用shell
1
$ watch "echo stats | nc 127.0.0.1 11211"
结果如下：
1

STAT pid 13785
STAT uptime 1377436
STAT time 1227764242
STAT version 1.2.6
STAT pointer\_size 32
STAT rusage\_user 9.265591
STAT rusage\_system 36.541444
STAT curr\_items 6
STAT total\_items 1093
STAT bytes 24628
STAT curr\_connections 19
STAT total\_connections 79352
STAT connection\_structures 117
STAT cmd\_get 609575
STAT cmd\_set 1093
STAT get\_hits 608483
STAT get\_misses 1092
STAT evictions 0
STAT bytes\_read 14703639
STAT bytes\_written 2297950214
STAT limit\_maxbytes 52428800
STAT threads 1
END
- 使用php进行查询
1
watch '/www/php/bin/php -r '"'"'\$m=new Memcache;\$m-\>connect("127.0.0.1", 11211);print\_r(\$m-\>getstats());'"'"
结果如下：
1

上面命令假设memcached按默认情况运行，即服务器地址为127.0.0.1，端口为11211。请按实际情况修改。
