Stats display status, if he will pop up a lot of things after carriage return, some data we need to pay attention to

Such as:

Get_hits is a get query, the number of times it is queried

Get_misses with Get query, the number of times not queried

Cmd_get total number of queries executed

Curr_items the number of keys currently present (including expired)

Main view hit rate problem:

Get_hits/cmd_get the higher the ratio, the better the system.

Note that the setting of the data validity period

There are two kinds of settings

• Set the number of seconds directly, set the cache time using the number of seconds, you can not 30 days
• Set a time-out point for the time stamp to expire.

Regardless of the time stamp or the number of seconds are integers, how to distinguish and?

If less than 30*24*3600 is the number of seconds to set, if the value is more than the timestamp,

If the set cache validity period is greater than 30*24*3600 less than the current timestamp, it indicates that it is invalid
