SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps teams detect post-deploy issues by continuously watching the live app for console errors, performance regressions, and visual anomalies.

Core Features & Use Cases

  • Continuous post-deploy monitoring with browse daemon
  • Captures console errors, performance regressions, and page failures
  • Takes periodic screenshots and compares against pre-deploy baselines
  • Alerts on anomalies to the team

Quick Start

Run the canary skill after deployment to start monitoring the live app for anomalies.

FAQPage Schema
How do I monitor my live web app for errors after a production deployment?

Post-deploy production monitoring continuously watches live web apps for console errors, performance regressions, and page failures using a browsing daemon to detect issues immediately after deployment.

Can I detect visual regressions in production after deploying?

Visual regression detection in production works by taking periodic screenshots post-deploy and comparing them against pre-deploy baselines to automatically identify and alert the team on visual anomalies.

What is a canary test and when do I need it for my web application?

A canary test continuously checks live app health, captures console logs and performance metrics, and alerts on anomalies, needed whenever you must detect post-deploy issues in production without manual intervention.

Do I need a browsing daemon to run continuous post-deploy checks?

Continuous post-deploy checks require a browsing daemon and integration hooks to actively capture console logs, performance metrics, screenshots, and trigger anomaly alerts in the live environment.

How do I get alerts for performance regressions and page failures post-deploy?

Post-deploy performance regression and page failure alerts are generated by continuously monitoring live app health metrics and automatically notifying the team when anomalies are detected.

What are the limitations of using automated canary tests for production monitoring?

Automated canary tests for production monitoring are limited to web apps and depend entirely on the browsing daemon and integration hooks being active to capture console logs, metrics, and visual regressions.
