Hands-on Workshop: Envoy Metrics Demystified Workshop
summary
Hands-on walkthrough that uses Prometheus + Grafana and an Envoy-based mesh to turn raw stats into dashboards. Workshop boots a three‑tier demo (API → payments [3 instances, one V2 misconfigured to return 20% errors] → currency gRPC with V2 also 20% errors), shows queries like envoy_listener_downstream_cx, uses rate() and label_replace() to get requests/sec (~12 rps / ~12 active connections) and histogram_quantile() for p50/p95 latency, and builds panels that reveal retries, 5xx spikes, and noisy-instance root causes.
