Recording rules allow you to precompute frequently needed or computationally expensive PromQL expressions and save their results as a new set of time series in Prometheus' time series database (TSDB). This training teaches you the basic motivations and concepts behind recording rules, as well as how to create and use them in your Prometheus setup.

After this training, you will be able to explain how recording rules work and be able to use them to improve the performance or capabilities of your Prometheus setup.
