SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy production monitoring solves the problem of catching issues that slip through CI by watching a live URL for anomalies. It operates across scenarios like quick verification after deploy, long-running monitoring with a baseline comparison, and page-level health checks using the browse daemon. It satisfies requirements for baseline handling, page selection, and timed monitoring windows.

Core Features & Use Cases

  • Post-deploy monitoring with the browse daemon to watch live apps.
  • Periodic screenshots, baseline comparisons, and anomaly alerts.
  • Baseline capture, page discovery, and targeted monitoring after deployment.

Quick Start

Run /canary <url> after deployment to monitor the app for 10 minutes and surface issues.

FAQPage Schema
How do I monitor a production URL for anomalies after a deployment?

To monitor a production URL for anomalies after a deployment, run a post-deploy monitoring command against the live app to watch the URL and surface issues that slipped through CI.

What is post-deploy production monitoring and how does it catch issues that CI misses?

Post-deploy production monitoring catches issues that CI misses by watching a live URL for anomalies, taking periodic screenshots, and comparing against a captured baseline to alert on regressions.

Can I do baseline comparisons during long-running production monitoring?

Yes, you can perform baseline comparisons during long-running production monitoring by capturing an initial baseline and comparing subsequent periodic screenshots to detect visual or page-level anomalies.

How do I run a quick health check on a live app after deploying?

You can run a quick health check on a live app after deploying by executing a monitoring command against the target URL to verify page-level health and surface issues over a timed monitoring window.

Does post-deploy monitoring require the browse daemon for page-level health checks?

Yes, post-deploy monitoring uses the browse daemon to perform page-level health checks, discover pages, and watch live apps for anomalies during the specified monitoring window.

What is the best way to set up timed monitoring windows for production alerts?

The best way to set up timed monitoring windows for production alerts is to initiate a post-deploy monitoring session that watches the live URL for a set duration, such as a 10-minute timed window, to surface issues.
