# redis
redis 的监控原理,就是连上 redis执行 info 命令,解析结果,整理成监控数据上报。
## Configuration
redis 插件的配置在 `conf/input.redis/redis.toml` 最简单的配置如下:
```toml
[[instances]]
address = "127.0.0.1:6379"
username = ""
password = ""
labels = { instance="n9e-10.23.25.2:6379" }
```
如果要监控多个 redis 实例,就增加 instances 即可:
```toml
[[instances]]
address = "10.23.25.2:6379"
username = ""
password = ""
labels = { instance="n9e-10.23.25.2:6379" }
[[instances]]
address = "10.23.25.3:6379"
username = ""
password = ""
labels = { instance="n9e-10.23.25.3:6379" }
```
建议通过 labels 配置附加一个 instance 标签,便于后面复用监控大盘。
## 监控大盘和告警规则
该 README 的同级目录下,提供了 dashboard.json 就是监控大盘的配置alerts.json 是告警规则,可以导入夜莺使用。
