I’ve spent a bit of time setting up Linux (in my case, CentOS) as a home router due to frustrations with home routers available on the market. This was both a good exercise and a bit of nostalgia from my early days with Linux. Once I’d finished getting the basics set up, I wanted a way to track various statistics, such as network traffic, disk usage, etc. The venerable Cacti is certainly an option, but that’s feeling a bit legacy these days. I’d prefer to use a newer tool with a more modern feel. This is what led me to Grafana. This is a basic walkthrough for how I’ve set things up. This is a basic install that incorporates collectd, InfluxDB, and Grafana on the same host.
