Grafana + Prometheus + fping-exporter 搭建网络监控

@LALALAYES #60 嗯嗯 需要自己设置一个变量来替换掉IP，并且在prometheus里需要加上对应的字段

@zenitsu #61
佬，我大概看了一下，和这个一样是吗，把对应的数据改一下就行，一台vps一个job_name

@LALALAYES #62 我tg发你个例子吧

卡在这一步

root@debian:~# sudo apt-get install grafana

绑定一下

装这三个磁盘占用多吗，我感觉还是哪吒简单一点

@av #66
取决于prometheus多久抓取一次数据和数据会保留多长时间，抓取周期配置类似下方：

global:
    scrape_interval: 15s

数据保留时间要看你是怎么安装的，如果是直接装要在systemd service里修改，用docker-compose安装的在docker-compose.yml里改

command:
    - '--storage.tsdb.retention.time=180d'

我抓的是node-exporter的数据，大概按照上面的配置，20台小鸡，占用空间在30-35G左右，当然楼主这种只监测ping的占用的空间应该会小很多，几个G应该就能搞定

@satorik #67 好的，感谢说明，有空练练手，鸡腿奉上

有没有docker的那种一键的包呢，确实想偷懒

@RemixOS #69 没有捏
