SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps you detect runtime issues early by watching live apps for console errors, performance regressions, and page failures so you can respond before users are affected.

Core Features & Use Cases

  • Watches the live application after deploy for runtime errors, slowdowns, and failed navigations.
  • Takes periodic screenshots and compares them against pre-deploy baselines to surface anomalies.
  • Alerts the team when deviations exceed thresholds, enabling rapid rollback or remediation.
  • Use cases include verifications after release, production health checks, and quick validation of critical user flows.

Quick Start

After deploying a new release, enable canary monitoring and let it run against the production environment to surface issues automatically.

FAQPage Schema
How does post-deploy canary monitoring detect runtime issues in live applications?

Post-deploy canary monitoring detects runtime issues by watching live deployments to surface console errors, performance regressions, and page failures before end users are affected. It applies pre-deploy baselines and periodic screenshots to identify anomalies automatically.

What is the best way to monitor production health after a new release?

The best way to monitor production health after a release is to enable canary monitoring against the live environment. It watches for slowdowns, failed navigations, and runtime errors, alerting the team when deviations exceed thresholds for rapid rollback or remediation.

How do I set up alerts for performance regressions in production watch tasks?

To set up alerts for performance regressions, enable canary monitoring to run periodic checks against your production environment. It generates actionable alerts and triage guidance when deviations exceed established thresholds, enabling rapid remediation.

Does canary monitoring work with pre-deploy baselines to surface anomalies?

Yes, canary monitoring works with pre-deploy baselines by taking periodic screenshots of the live application and comparing them against the baseline state. This comparison surfaces visual and performance anomalies automatically after deployment.

Can I use canary monitoring for quick validation of critical user flows in production?

Yes, you can use canary monitoring for quick validation of critical user flows in production. It operates across post-deploy scenarios and production watch tasks to verify runtime health, detect slowdowns, and surface failed navigations automatically.

When should I not rely on canary monitoring for deployment verification?

You should not rely on canary monitoring alone when you lack pre-deploy baselines for comparison, as the tool depends on contrasting periodic screenshots against baseline states to accurately surface anomalies and performance regressions.
