Modern Network Observability#
CfgMgmtCamp Ghent 2026 digest Program Core pick 2–4 February 2026
Christian Adell, Staff Network Developer at CoreWeave, co-author of Modern Network Observability (Packt)
- Why: Four-hour hands-on workshop on modern network telemetry — gNMI/streaming telemetry through to event-driven automation — taught by someone who builds large-scale network automation at CoreWeave, i.e., at GPU-cloud DC scale. This is the most directly relevant item in the whole program to physical/network telemetry work.
- What: Building a complete open-source network observability stack from scratch: collection and normalization (Telegraf), streaming storage (Prometheus), contextual dashboards (Grafana correlating metrics, traces, and topology), and event-driven pipelines (Kafka/NATS/webhooks) that trigger network automation from telemetry (from abstract only).
- How: Lab-based on Containerlab with Python >3.10 and Docker locally (or a DigitalOcean playbook), moving from raw gNMI/streaming telemetry to modeled, correlated, and reactive telemetry integrated into CI/CD and automation workflows.
- Where applicable: Broadly applicable — vendor-neutral, open-source stack on containerized lab topology. The event-driven automation angle (telemetry → Kafka/NATS → automated action) is the piece most programs skip and is directly relevant to DC fabric operations. Budget the full morning; it's a workshop, not a talk.
