Prometheus, a Solar Inverter and Other Home Metrics

Practical home observability.
This talk introduces the fundamentals of metrics and demonstrates how to collect, store and explore them with Prometheus through a series of real-world examples. We'll look at data from a solar inverter, smart plugs, temperature and ultrasonic sensors, network latency and even birdsong in the garden.

Whether you're new to metrics or just getting started with Prometheus, you'll learn the basics of time-series databases, metric scraping, building a simple exporter, querying data with PromQL and visualizing the results.
