From Telemetry to Automated Incident Response: My DevOps & Observability Journey # observability # ai # opentelemetry # devops Description: A hands-on learning journey building observability and automated incident response into a FastAPI order-tracking application using OpenTelemetry, Prometheus, Loki, Tempo, Grafana, and Codex CLI. From Telemetry to Automated Incident Response As part of the DataTalksClub AI Dev Tools Zoomcamp , I worked on a small but practical challenge: turning a simple FastAPI application into an observable system with automated incident response. The project started as a basic Order Tracker application backed by SQLite. By the end, it had evolved into a system that could: collect metrics, logs, and traces visualize telemetry in Grafana detect application errors through alerting send incidents to an incident-response service provide evidence for investigation trigger a coding agent to investigate and remediate an issue The most valuable lesson for me wa...
