Nice tutorial/guide for setting up grafana for Plex media server.

This is a bit older, but still relevant. It's a handy guide for configuring grafana to work with prometheus for monitoring a Plex media server. The configurations assume certain graphics cards but otherwise work fine.

TLDR

This video tutorial demonstrates how to create an advanced Plex dashboard using Prometheus, Grafana, and Docker to monitor CPU, GPU, disk health, network usage, and Plex streams, providing insights to prevent buffering and detect server issues.
