Observability is one of the core features that Linkerd brings to the table, and metrics are one of the most important — and least understood! — aspects of observability. Watch this deep dive into the world of Linkerd metrics! We’ll start with a quick overview of how Linkerd works with a Prometheus store to generate and save metrics (including how to query arbitrary metrics from the command line), spend some time diving into what the various metrics really mean, and then finish up by building a custom Grafana dashboard to show some useful things about our demo app. You’ll walk away with practical, real-world knowledge to help you make sense of metrics!
