解析rdb, aof, 以及执行monitor, 来查找key和分析各种top-key(big key, hot-key, expiry-key, slowlog-key)
go get github.com/lanfang/redis-analyzer
执行redis-analyzer来查看帮助信息，各功能模块以子命令的方式提供，子命令有自己的参数
redis-analyzer
Usage:
redis-analyzer [command]
Available Commands:
bigkey Find the key over the specified size
dump Dump rdb file from redis server

help Help about any command
keys Grep key through the golang regular
monitor A query analyzer that parses redis monitor command

通过指定rdb文件或者redis服务器，来分析各种key，具体查看帮助信息
$ redis-analyzer parse-rdb --node "127.0.0.1:6379,127.0.0.1:6479,127.0.0.1:6579" --on-master --pretty --top-num 1 --output ./parse_rdb_result --log-file ./logxxx
$ cat parse_rdb_result_127.0.0.1:6379

database abnormal key
database top key: redis服务器里面按照key size排序结果
database top key by type: 每种数据类型按照key排序结果
database expiry key: 根据日期正则匹配，查找未设置过期时间的key(可以通过keys命令实行此功能)
database abnormal key: 根据正则匹配key
其余命令的使用方法可以参考--help信息 parse-aof只是实现了解析本地aof文件以及连接redis server 作为fake-redis存在, 未对解析出来的命令做具体的统计操作，如果有需要的话可以自行修改
