Observability for Emerging Infra: What Got You Here Won't Get You There
summary
Argues that traditional metrics and dashboards fail because they destroy context and prevent asking new questions, shows Facebook’s Scuba cutting debug time from days to seconds and describes building Honeycomb to replicate that; gives concrete failures (Parse push bottleneck that broke only behind one router, Instagram’s hyperlocal spikes), prescribes structured high‑cardinality event data, event‑level sampling, and says teams can delete most alerts once they can slice and dice by 99.8% uptime and individual requests.
