慢查询分析

1. slowlog-log-slower-than 参数单位微秒

   127.0.0.1:6379> config get slowlog-log-slower-than
   1) "slowlog-log-slower-than"
   2) "10000"
   

2. slowlog-max-len参数 慢查询日志长度 ```shell 127.0.0.1:6379> config get slowlog-max-len 1) "slowlog-max-len" 2) "128"

3. 获取慢查询日志
```shell
127.0.0.1:6379> slowlog get

1. 获取慢日志长度

   127.0.0.1:6379> slowlog len
   

2. 慢日志重置

   127.0.0.1:6379> slowlog reset
