前言

对于任何应用服务和组件，都需要一套完善可靠谱监控方案。

尤其redis这类敏感的纯内存、高并发和低延时的服务，一套完善的监控告警方案，是精细化运营的前提。

本文主要给大家介绍了关于redis状态监控和性能调优的相关内容，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧。

1、redis-benchmark

redis基准信息，redis服务器性能检测

例如：

检测redis服务器性能，本机6379端口的实例，100个并发连接，100000个请求

redis-benchmark -h localhost -p 6379 -c 100 -n 100000

[root@redis-server ~]# redis-benchmark -h localhost -p 6379 -c 100 -n 100000

2、redis-cli

例1：监控本机6379端口的实例的数据操作，redis的连接及读写操作

redis-cli -h localhost -p 6379 monitor

先开启一个终端1，用于redis监控

[root@redis-server ~]# redis-cli -h localhost -p 6379 monitor

OK

1504689350.635365 [0 127.0.0.1:57996] "COMMAND"

1504689361.944610 [0 127.0.0.1:57996] "set" "a" "1"

1504689369.782029 [0 127.0.0.1:57996] "get" "a"

然后在开启一个redis终端2进行操作

[root@redis-server ~]# redis-cli -p 6379

127.0.0.1:6380> set a 1

OK

127.0.0.1:6380> get a

"1"

127.0.0.1:6380>

可以看到终端2上面进行的数据操作会在终端1上面被记录下来

例2：查询本机redis实例的信息，端口6379

redis-cli -h localhost -p 6379 info

备注：该命令也可以在redis终端里面进行查询

[root@redis-server ~]# redis-cli -h localhost -p 6379 info
