What does Memcache's hit rate specifically mean?

Hit rate =get_hits/cmd_get * 100%

• cmd_get#get命令 (gets) The total number of requests

• get_hits#总命中次数

Memcache's hit rate usually refers to how much of a chance to hit the memcache cache when fetching data.
Usually used to memcache time is the cluster, then the cluster will inevitably have n memcached server, different servers have different data, then when the data is taken: (successfully from the memcached data/Total Data requests). This is the hit rate.
