Redis Config Resetstat 命令用于重置 INFO 命令中的某些统计数据,包括:
Keyspace hits (键空间命中次数)
Keyspace misses (键空间不命中次数)
Number of commands processed (执行命令的次数)
Number of connections received (连接服务器的次数)
Number of expired keys (过期key的数量)
Number of rejected connections (被拒绝的连接数量)
Latest fork(2) time(最后执行 fork(2) 的时间)
The aof_delayed_fsync counter(aof_delayed_fsync 计数器的值)
redis Config Resetstat 命令基本语法如下:
redis 127.0.0.1:6379> CONFIG RESETSTAT
>= 2.0.0
总是返回 OK 。
重置前 INFO 命令输出信息:

重置后查看 INFO 命令输出信息:
