SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps teams catch issues that slip through local testing by watching a live URL for console errors, performance regressions, and page failures, and by capturing baselines for comparison.

Core Features & Use Cases

Baseline capture before and after deploys to establish performance and error benchmarks.
Continuous, scheduled checks (e.g., every 60s) across defined pages to detect anomalies.
Alerting and guidance when regressions or errors appear, with actionable next steps.
Use Case: Validate a new release in production by comparing current metrics against a pre-deploy baseline.

Quick Start

Invoke the canary monitor with /canary <url> and optional flags to customize duration, pages, and baseline capture.

FAQPage Schema

What is post-deploy canary monitoring and how does it catch production issues?▼

Post-deploy canary monitoring captures a performance and error baseline, then continuously checks a live URL for console errors, performance regressions, and page failures to detect production anomalies after a release.

How do I monitor a live URL for console errors and performance regressions after a release?▼

You can monitor a live URL by invoking the canary monitor with your target URL and optional flags to customize duration, pages, and baseline capture, scheduling periodic checks to identify production issues.

Can I customize the monitoring duration and pages for post-deploy validation?▼

Yes, you can customize monitoring duration and pages for post-deploy validation using optional flags when you invoke the canary monitor, allowing scheduled checks across defined pages at intervals like every 60 seconds.

Does canary monitoring work for web apps and pages without external dependencies?▼

Yes, canary monitoring works for post-deploy validation workflows across web apps and pages with no external dependencies, applying page discovery and anomaly detection to satisfy end-to-end canary monitoring requirements.

What is the best way to validate a new release in production against a pre-deploy baseline?▼

The best way to validate a new release in production is capturing a pre-deploy baseline for performance benchmarks, then comparing current live metrics against it to alert when regressions or errors appear.

What happens when console errors or performance regressions are detected during monitoring?▼

When console errors or performance regressions are detected during monitoring, the canary monitor provides structured alerting and actionable guidance with next steps to resolve the detected production anomalies.
