categraf采集redis指标

• 修改categraf配置

• 导入监控大盘

修改categraf配置

# vim conf/input.redis/redis.toml 
[[instances]]
address = "10.0.1.5:6379"
labels = { instance="10.0.1.5:6379", env="test" }

这里在[[instances]]
下配置了labels，和[global.labels]
配置是有区别的。[[instances]]
只对当前实例有效。

如果redis配置了用户名和密码，也可以使用username
和password
来进行配置。

[[instances]]
也意味着是数组，即可以配置多个redis实例，而不用像exporter要部署多个监控实例。

重启categraf

# systemctl restart categraf

导入监控大盘

在【监控看图】-【监控大盘】选择导入大盘

直接可以搜索redis，选择redis_by_categraf

进入大盘即可查看展示的监控数据

默认大盘显示的数据比较少，可根据实际情况进行添加。支持的redis监控指标如下：
