SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy Canary monitoring addresses the need to detect production issues quickly by watching live apps for console errors, performance regressions, and page failures. It automates baseline comparisons and can trigger alerts when anomalies are detected, reducing MTTR after deployments.

Core Features & Use Cases

  • Live post-deploy monitoring with console-error detection, performance regression tracking, and page-failure alerts.
  • Periodic screenshots with baseline comparisons to surface visual regressions and drift.
  • Integration with canary deployment workflows to validate stability before full rollout.

Quick Start

Enable post-deploy monitoring and let the canary watch live production, capture periodic screenshots, compare against baselines, and alert on anomalies.

FAQPage Schema
How does post-deploy canary monitoring detect production issues?

Post-deploy canary monitoring detects production issues by watching live apps for console errors, performance regressions, and page failures. It relies on a browse daemon and baseline data to identify anomalies that exceed expected thresholds.

Can I use canary monitoring to validate stability before a full rollout?

Yes, canary monitoring integrates with canary deployment workflows to validate stability before full rollout. It monitors staging and production deployments, comparing live behavior against baseline thresholds to trigger alerts on detected anomalies.

How do I set up visual regression tracking for live production apps?

Visual regression tracking for live production apps is set up by enabling post-deploy monitoring to capture periodic screenshots. These screenshots are automatically compared against established visual baselines to surface visual regressions and drift.

What is the best way to alert on performance regressions after a deployment?

The best way to alert on performance regressions after a deployment is to run automated canary monitoring against live apps. It tracks performance metrics, compares them with baseline data, and triggers alerts when anomalies exceed expected thresholds.

Do I need baseline data to detect console errors and page failures in staging?

Yes, baseline data is required to detect console errors and page failures in staging. Canary monitoring relies on these baselines to perform comparisons and determine when live application anomalies exceed expected operational thresholds.
