SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Observability helps teams understand production behavior and respond quickly to incidents by consolidating logs, metrics, and traces into a cohesive view.

Core Features & Use Cases

  • End-to-end correlation IDs across services to trace requests.
  • Centralized logging with Sentry for error tracking.
  • Real-time analytics and dashboards using PostHog.
  • Alerts and incident response workflows to detect and respond to failures.
  • Platform-ready guidance for environments like Vercel.

Quick Start

Configure your observability stack by enabling logging, metrics, and tracing in your app, setting up Sentry and PostHog, and deploying to your platform. Then verify end-to-end tracing and alerting in your dashboards.

FAQPage Schema
How do I implement logging, metrics, and tracing across my application?

Implement comprehensive observability by enabling structured logging, metrics collection, and tracing in your app, then configure correlation IDs to track requests end-to-end across services. Set up centralized platforms like Sentry for error tracking and PostHog for real-time analytics to consolidate all signals into a cohesive view.

What's the best way to trace requests across multiple services?

Use end-to-end correlation IDs to trace requests through your entire system. Propagate these IDs across service boundaries so logs, metrics, and traces from each service link together, enabling you to reconstruct the full request path during incident investigation.

How do I set up alerts and respond to production incidents faster?

Configure alerting on critical failures and establish incident-response workflows that detect issues automatically. By correlating logs, metrics, and traces, you can identify root causes quickly and respond before users are significantly impacted.

Can I use observability practices on Vercel and other cloud platforms?

Yes. This guidance includes platform-specific recommendations for environments like Vercel, covering how to configure logging, metrics, and tracing within platform constraints and integrate with Sentry and PostHog.

Do I need separate tools for logging, metrics, and tracing?

You can use specialized tools like Sentry for centralized error logging and PostHog for real-time analytics and dashboards. Integrating these with your application's native tracing ensures all three signals work together to provide complete observability.

Why is observability important before incidents happen?

Observability enforces configuration, instrumentation, and incident-response readiness upfront. When production issues occur, you already have structured logs, metrics, and traces in place, enabling fast diagnosis and response instead of scrambling to gather data.
