  • 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)
