SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Canary monitoring helps teams verify production health by continuously watching a live URL after deployment, surfacing errors, performance regressions, and page failures before users are impacted.

Core Features & Use Cases

  • Baseline capture and comparison to detect regressions
  • Page discovery to enumerate important routes
  • Continuous monitoring with adjustable duration and per-page checks
  • Health alerts and reports for quick triage

Quick Start

Run the /canary command with the target URL after deployment to begin monitoring.

FAQPage Schema
What is post-deploy canary monitoring and how does it detect production regressions?

Post-deploy canary monitoring continuously observes a live URL after deployment to detect production issues, surfacing errors, performance regressions, and page failures before users are impacted. It compares live metrics against a captured baseline to identify issues.

How do I start monitoring my production URL for health checks after a deployment?

Run the /canary command with the target URL after deployment to begin monitoring. The Skill performs continuous health checks with adjustable duration and per-page checks to verify production health.

Do I need a browser daemon and baseline data to run canary health checks?

Yes, canary monitoring requires a browser daemon, baseline data, and a clearly defined set of pages to monitor. These prerequisites ensure that baseline comparisons stay meaningful during post-deploy checks.

How does page discovery work for continuous production monitoring?

Page discovery enumerates important routes within the application to define the set of pages for continuous monitoring. This ensures comprehensive post-deploy canary checks across the app rather than just a single entry point.

Can I adjust the duration of canary monitoring for my post-deploy checks?

Yes, continuous monitoring features adjustable duration and per-page checks. You can configure the monitoring window to match your deployment stabilization period and receive health alerts and reports for quick triage.

Why do my canary health checks show false positives during production monitoring?

Canary monitoring false positives often occur when baseline data is outdated or the defined set of pages to monitor is inaccurate. Ensuring baseline comparisons stay meaningful requires accurate baseline capture and consistent page discovery.
