SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring catches issues that slip through CI by watching a live URL for console errors, performance regressions, and page failures, and by taking periodic screenshots to compare against baselines.

Core Features & Use Cases

  • Baseline capture before deployment to establish a reference state.
  • Continuous monitoring of selected pages with automated alerts for anomalies.
  • Detailed health reports and targeted alerts to guide post-deploy action.

Quick Start

Start a canary run on your site after a deployment to begin monitoring and alerting on issues.

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

To monitor a production URL for errors after a deployment, configure a canary run to continuously check page health, log console errors, and capture periodic screenshots to detect post-deploy anomalies.

What is post-deploy canary monitoring and how does it work?

Post-deploy canary monitoring is a process that catches production issues by watching a live URL for console errors, performance regressions, and page failures using a browser automation daemon to alert on anomalies.

How do I establish a performance baseline before deploying changes?

To establish a performance baseline before deploying changes, capture a reference state of your selected pages using the baseline capture feature, allowing accurate comparison for performance regressions later.

Can I configure alert thresholds for production performance monitoring?

Yes, you can configure alert thresholds for production performance monitoring by tailoring the canary runs to your deployment workflow, setting specific timing baselines and pages to monitor for automated anomaly alerts.

What is the best way to detect page health regressions in a live production environment?

The best way to detect page health regressions in a live production environment is using continuous canary monitoring with a browser automation daemon to compare current page health against pre-deployment baselines.
