Cilium & Grafana LGTM! - Raymond de Jong
summary
Cilium uses eBPF to emit Prometheus metrics and Hubble to surface rich layer‑7 HTTP metrics that feed Grafana dashboards; a live demo increases request volume, deploys a faulty config that raises 500s and duration, then enables OpenTelemetry so Hubble exports exemplars link metrics to traces that Tempo can fetch. Ready‑made Grafana dashboards and operator/agent metrics are shown, and key claims are that you get no app changes for golden signals, that exemplars require instrumentation, and that the demo metrics and tracing workflow work end‑to‑end.
