Mikrotik
- 使用 snmp 采集数据
- 仓库地址https://github.com/IgorKha/Grafana-Mikrotik，此仓库提供了
mashinkopochinko/snmp_exporter_mikrotik:latest，但是我喜欢使用最新的版本，把[https://github.com/IgorKha/Grafana-Mikrotik/blob/master/snmp/snmp.yml](https://github.com/IgorKha/Grafana-Mikrotik/blob/master/snmp/snmp.yml)文件下载到本地，使用prom/snmp-exporter:latest挂载snmp.yml
- 启动后默认端口 9116
- 配置 routeros snmp

关于怎么省 Metrics
- 因为只有 10K，跑 node_exporter 就能占 1K 多，所以需要只收集需要的指标

这个就不用省了，原本就不多
Mikrotik
指标基本都需要，如果有不需要的可以自定义精简 snmp.yml
DPM
每分钟数据点，不能大于 1，所以所有 agent 上报间隔需要设置为 60s 以上
