SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps Release Reliability Engineers detect production issues quickly by watching a live app post-deploy, capturing baselines, and surfacing anomalies before users notice.

Core Features & Use Cases

Real-time canary monitoring: watch the live app, capture screenshots, check console errors, and measure page performance after deployment.
Baseline and anomaly detection: take baseline measurements before changes and compare against current runs to flag regressions.
Flexible scope: specify duration, pages, and targeted URLs, with quick feedback on overall health.

Quick Start

Run a canary session against your deployed URL to begin monitoring and alerting.

FAQPage Schema

How do I monitor a live app for production issues after a deployment?▼

You can run a canary monitoring session against your deployed URL for a configurable duration, capturing baseline screenshots and checking console errors, performance regressions, and page failures across multiple pages.

How does baseline capture work for detecting performance regressions?▼

Baseline capture takes measurements before changes are deployed, allowing subsequent canary monitoring runs to compare current live app behavior against the baseline to flag performance regressions and anomalies.

Can I monitor multiple pages and capture screenshots during a canary check?▼

Yes, canary monitoring supports capturing baseline screenshots and monitoring multiple pages simultaneously, utilizing a live grid of browser agents to provide quick feedback on overall application health.

What is the best way to detect console errors and page failures in production?▼

Running a post-deploy canary session is an effective way to detect console errors and page failures, leveraging a live grid of browser agents to watch the live app and surface anomalies quickly.

Does canary monitoring support plan-mode safe operations with telemetry output?▼

Yes, the canary monitoring skill implements plan-mode safe operations and provides structured telemetry output, including optional telemetry and logging, to ensure safe and observable post-deploy checks.
