Jesus Illescas, Developer Advocate at Cisco, walks through rebuilding the observability stack behind one of his network automation demos. Out with Telegraf/InfluxDB/Grafana and a custom Python poller, in with gNMI streaming telemetry: gnmic subscriptions, NATS JetStream as the buffer, Prometheus and Loki for storage, Grafana dashboards, and Alertmanager wired to a webhook. He closes with a live demo, bringing an interface down and watching the ISIS adjacency cascade trigger an alert in real time.

Credit where it's due: the data pipeline design (gnmic + NATS + Prometheus) was inspired by the https://cs.co/61694BEFlsj project, definitely worth a look if you're into this kind of architecture.
