SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps teams detect errors, performance regressions, and page failures in a live app before issues reach customers.

Core Features & Use Cases

  • Canary monitoring watches live production for console errors, performance regressions, and visual issues.
  • It takes periodic screenshots, compares them against pre-deploy baselines, and raises alerts on anomalies.
  • Use cases include validating deployments, catching regressions early, and guiding post-deploy remediation.

Quick Start

Start canary monitoring after deploy to watch production, capture baselines, and alert on anomalies.

What is canary monitoring and how does it work?

Canary monitoring uses a browse daemon to watch live production, capturing periodic screenshots and telemetry to compare against pre-deploy baselines, raising alerts when visual or performance anomalies are detected.

How do I start canary monitoring after a deployment?

You start canary monitoring after deploy to watch production, capture baselines, and alert on anomalies, integrating with the gstack workflow to orchestrate post-deploy verification and continuous health monitoring.

Does canary monitoring work with the gstack workflow?

Yes, canary monitoring integrates with the gstack workflow to orchestrate post-deploy verification and continuous production health monitoring using the browse daemon.

Why do I need pre-deploy baselines for canary monitoring?

Pre-deploy baselines are required for canary monitoring to compare against periodic screenshots taken post-deploy, allowing the detection of visual issues, performance regressions, and page failures before they reach customers.
