Near-Realtime Monitoring of Drones at Sea
summary
Saildrone builds a near‑real‑time monitoring system called Sonar that runs on TypeScript/Node.js with Redis hot cache, Postgres, AWS SQS, Kubernetes and Docker, and ties into Slack and PagerDuty. It encodes 900+ configurable checks across 350+ telemetry variables (and has executed those checks over 100 million runs) to auto‑create incidents, page operators, and close issues when corrected, replacing people who used to stare at graphs for hours.
