实时查询memcached状态的两个快捷命令

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）：

 

1. watch "echo stats | nc 127.0.0.1 11211"

 

结果如下：

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

 

2. watch '/www/php/bin/php -r '"'"'$m=new Memcache;$m->connect("127.0.0.1", 11211);print_r($m->getstats());'"'"

 

结果如下：

Array
(
    [pid] => 13785
    [uptime] => 1377469
    [time] => 1227764275
    [version] => 1.2.6
    [pointer_size] => 32
    [rusage_user] => 9.266591
    [rusage_system] => 36.541444
    [curr_items] => 6
    [total_items] => 1093
    [bytes] => 24628
    [curr_connections] => 16
    [total_connections] => 79372
    [connection_structures] => 117
    [cmd_get] => 609593
    [cmd_set] => 1093
    [get_hits] => 608501
    [get_misses] => 1092
    [evictions] => 0
    [bytes_read] => 14704073
    [bytes_written] => 2298032330
    [limit_maxbytes] => 52428800
    [threads] => 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。
