SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps teams detect console errors, performance regressions, and page failures in real time by watching live deployments and comparing against baselines.

Core Features & Use Cases

  • Canary-based monitoring with periodic screenshots, baseline comparisons, and anomaly alerts.
  • Telemetry-backed health checks for production readiness and rapid rollback decisions.
  • Use cases include validating new deployments, catching regressions early, and maintaining user experience during rollouts.

Quick Start

Start the canary monitor on your production deployment to begin baseline comparisons and alerting.

FAQPage Schema
How do I monitor a live application for post-deploy issues?

You can monitor a live application for post-deploy issues using the canary Skill to detect console errors, performance degradations, and page failures through continuous browse daemon monitoring. It requires a baseline comparison against pre-deploy measurements to alert on anomalies.

What is canary-based production monitoring?

Canary-based production monitoring is a technique that watches live deployments to catch regressions early by continuously checking browser-based UIs. It uses telemetry-backed health checks, periodic screenshots, and baseline comparisons to maintain user experience during rollouts.

Can I use this for validating production release readiness and rollback decisions?

Yes, you can use this for validating production release readiness and rapid rollback decisions. It applies telemetry-backed health checks to your deployment, comparing live metrics against pre-deploy baselines to determine if a release is stable or requires rollback.

How do I start a canary run for baseline comparison?

To start a canary run for baseline comparison, you initiate the canary monitor on your production deployment. It begins capturing pre-deploy measurements and uses defined probes to continuously monitor the live application, alerting you on any detected anomalies.

Does canary monitoring work with browser-based UIs?

Yes, canary monitoring works with browser-based UIs. It uses the browse daemon to continuously watch live applications for console errors, performance degradations, and page failures, making it suitable for ongoing reliability monitoring across web interfaces.
