Enterprise Troubleshooting
Routing Telemetry Signals Primer
BGP/OSPF telemetry you can export safely, baseline windows, and how to pair counters with troubleshooting hypotheses.
Overview
This primer stays routing-centric: which counters matter for adjacency health, prefix churn, and path stability. We avoid full observability platform sales language.
What is included
- Counter cheat sheet with sane sampling windows
- Lab: export BGP updates to a local collector
- Hypothesis template linking signals to tests
- Mentor review of one dashboard mock (optional)
- Ethics note on data minimization
- Glossary tuned for NOC handoffs
- Short capstone: narrate a fake incident from graphs only
Outcomes
- Pick three signals that justify deeper packet work
- Avoid dashboard noise during incidents
- Write a one-page telemetry appendix for runbooks

FAQ
Is programming required?
Light YAML/JSON edits only; we do not teach full-stack development.
Which collectors are used?
Open-source examples only; no vendor-specific licensing included.
Will this teach cloud cost ops?
No. We mention billing dashboards only as out-of-scope references.
Participant notes
“Routing Telemetry Signals Primer is short but dense. I wanted one more week of async Q&A; still worth it for the hypothesis template.”
