SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Observability removes blind spots in Cloudflare Workers and edge applications by making production behavior transparent through structured logging, distributed tracing, and error monitoring.

Core Features & Use Cases

  • Structured logging with correlation: Emit JSON log events that include trace and span identifiers so incidents can be followed end-to-end.
  • Request-scoped distributed tracing: Create trace IDs and spans that measure handler and subrequest timing for faster root-cause analysis.
  • Monitoring and alert-ready metrics: Capture errors and latency signals (e.g., error rate and percentiles) to support alerting and dashboards.
  • Use case: If an edge handler intermittently fails for certain requests, correlate ERROR logs to trace spans and capture stack traces plus request metadata to pinpoint the failing operation.

Quick Start

Use the observability skill to instrument your Cloudflare Worker by adding trace ID generation, structured JSON logging, span timing, and asynchronous log flushing via waitUntil.

FAQPage Schema
How do I add distributed tracing to Cloudflare Workers?▼

To add distributed tracing to Cloudflare Workers, generate trace IDs and create request-scoped spans that measure handler and subrequest timing for faster root-cause analysis across edge requests.

What is structured logging in edge applications?▼

Structured logging in edge applications emits JSON log events containing trace and span identifiers, allowing you to follow incidents end-to-end and capture stack traces upon failure.

How do I monitor error rates and latency percentiles in serverless edge functions?▼

Monitor error rates and latency percentiles in serverless edge functions by capturing errors and latency signals during execution, supporting alerting setup and operational dashboards for health visibility.

Can I ship logs asynchronously from Cloudflare Workers without blocking requests?▼

Yes, you can ship logs asynchronously from Cloudflare Workers by using the waitUntil API to flush structured JSON log events to an external collector without blocking the request lifecycle.

What is the best way to debug intermittent failures in edge handlers?▼

The best way to debug intermittent failures in edge handlers is to correlate ERROR logs to trace spans, capturing stack traces and request metadata to pinpoint the failing operation.
