used_memory_rss                      Redis分配的内存总量(包括内存碎片)              
used_memory_peak_human          Redis所用内存的峰值
mem_fragmentation_ratio         内存碎片所占百分比

aof_enabled                                         是否开启了aof

total_connections_received                    连接过客户端的总数量
total_commands_processed                  执行过命令的总数量
expired_keys                                       过期的 key 的数量
evicted_keys                                        删除过的key的数量
keyspace_hits                                      命中 key 的次数
keyspace_misses                                  未命中 key 的次数
role:master                                          当前redis角色master还是slave
db0                                                     每个数据库的 key 的数量,以及带有生存期的 key 的数量

通过hits和miss,计算缓存的命中率:26799568954 / (26799568954 + 12021752974) = 69% ,

充分利用缓存失效机制和过期时间的设计,命中率可以达到95%以上,对于整体性能提升很大

used_memory,expired_keys,evicted_keys这3个信息的具体含义,redis的官方也有一篇很详细的说明:http://redis.io/commands/info

有个ruby gem叫redis-stat,它利用INFO命令展现出更直观的信息报表,推荐:https://github.com/junegunn/redis-stat
