    CONFIG RESETSTAT

    可用版本： >= 2.0.0
    时间复杂度： O(1)

    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)

    返回值

    总是返回 OK 。
