命令行查看Memcached运行状态(shell或者telnet) 测试 Memcach

查看memcached状态的基本命令,通过这个命令可以看到如下信息:
|
stats items
输出各个slab中的item信息。s
stats slabs
输出slab中更详细的item信息
stats sizes
输出所有item的大小和个数
stats cachedump <slab_id> <limit_num>
利用shell命令操作Memcached
1、数据存储(假设key为g,value为12345)
printf "set g 0 0 5\r\n12345\r\n"|nc 127.0.0.1 11211 |
STORED
2、数据取回(假设key为zhangyan)
printf "get g\r\n"|nc 127.0.0.1 11211 |
VALUE g 0 5
12345
END
3、数值增加1(假设key为g,并且value为正整数)
printf "incr g 1\r\n" | nc 127.0.0.1 11211 |
12346
4、数值减少3(假设key为g,并且value为正整数)
printf "decr g 3\r\n" | nc 127.0.0.1 11211 |
12343
5、数据删除(假设key为g)
printf "delete g\r\n" | nc 127.0.0.1 11211 |
DELETED
6、查看Memcached状态
printf "stats\r\n" | nc 127.0.0.1 11211 |
STAT pid 3025
STAT uptime 4120500
STAT time 1228021767
STAT version 1.2.6
STAT pointer_size 32
STAT rusage_user 433.463103
STAT rusage_system 1224.515845
STAT curr_items 1132460
STAT total_items 8980260
STAT bytes 1895325386
STAT curr_connections 252
STAT total_connections 547850
STAT connection_structures 1189
STAT cmd_get 13619685
STAT cmd_set 8980260
STAT get_hits 6851607
STAT get_misses 6768078
STAT evictions 0
STAT bytes_read 160396238246
STAT bytes_written 260080686529
STAT limit_maxbytes 2147483648
STAT threads 1
END
7、模拟top命令,查看Memcached状态:
watch "printf 'stats\r\n' | nc 127.0.0.1 11211" |
或者
watch "echo stats | nc 127.0.0.1 11211"
一、echo stats items | nc127.0.0.1 11211
STAT items:1:number 998 Slab Id=1 ; items数量:998(也就是已经存储了998个key值)
STAT items:1:age 604348 Slab Id=1 ; 已经存在时间,单位秒
STAT items:1:evicted 0 Slab Id=1 ; 被踢出的数量
STAT items:1:evicted_nonzero 0
STAT items:1:evicted_time 0
STAT items:1:outofmemory 0
STAT items:1:tailrepairs 0
STAT items:1:reclaimed 0
STAT items:6:number 91897 Slab Id=6 ; items数量:91897(也就是已经存储了91897个key值)
STAT items:6:age 604345 Slab Id=6 ; 已经存在时间,单位秒
STAT items:6:evicted 0 Slab Id=6 ; 被踢出的数量
STAT items:6:evicted_nonzero 0
STAT items:6:evicted_time 0
STAT items:6:outofmemory 0
STAT items:6:tailrepairs 0
STAT items:6:reclaimed 0
