It covers setting up structured JSON logging via middleware, implementing custom OpenTelemetry traces with spans and attributes for key routes (score submission, leaderboard fetch, customization), and leveraging Deno Deploy's built-in Logs, Traces, and Metrics dashboards. The post explains how to correlate logs with traces, use span attributes for filtering, and interpret platform metrics like HTTP latency, CPU usage, and GC time. It also demonstrates using Deno Deploy's tunnel feature to verify instrumentation locally before deploying. ## Full article daily.dev links to this article rather than hosting it.
