 **Grafana**  
 Grafana is an open-source data visualization and monitoring platform. It has hundreds of features embedded that can help you query from data sources like Prometheus, InfluxDB, MySQL and so on...
 
-For todays guide I will show you how to setup a few exporters (node-exporter, smartctl) and collect their metrics with prometheus. Then visualize that data via graphana.

 Nix makes it trivial to set up these services, as there are already predefined options for it in nixpkgs. I will give you example configuration files below that you can just copy and paste.

 #### Smartctl
 
-Smartctl is a tool included in the smartmontools package. This is a collection of monitoring tools for hard-drives, SSDs and filesystems.  
-This exporter enables you to check up on the health of your drive(s). And it will also give you a wall notification if one of your drives has a bad sector(s), which mainly suggests it's dying off.

 ~16kB average per scrape (node-exporter). 1 day has 86400 seconds, divide that by 5 thats 17280 scrapes a day.  
 17280 \* 16 = 276480 kB. Thats 270 megabytes a day. And if you have multiple servers that causes X times as much.  
 30 days of scarping is about 8 gigabytes (1x). **But remember, by default prometheus stores data for 30 days!**
