Monitor Pi-hole with Netdata
Right before I started my paternity leave this summer, I finally bought a Raspberry Pi so I could use Pi-hole for network-wide ad+tracker blocking. Naturally, I had to install Netdata on the Pi to make sure I’m monitoring everything with per-second granularity.
This guide came out of that effort. If I can do it while helping take care of two young children, you can do it in a weekend!
