env:centos7+python2.7

`[root@openfalcon redis]# python redis-monitor.py
Traceback (most recent call last):

File "redis-monitor.py", line 116, in
main()

我把那个判断语句注释掉又出现

`[root@openfalcon redis]# python redis-monitor.py

Traceback (most recent call last):
File "redis-monitor.py", line 116, in
main()
File "redis-monitor.py", line 71, in main
value = float(stats['keyspace_hits'])/(int(stats['keyspace_hits']) + int(stats['keyspace_misses']))
KeyError: 'keyspace_hits'

@sylarjiang 可能是你redis版本过低，或者是一个全新的redis实例，我脚本改了下，遇到没有的key直接跳过了，你试试看是否ok了
