SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring ensures production health by watching live apps for console errors, performance regressions, and page failures, with automated baselines, screenshots, and alerting.

Core Features & Use Cases

  • Canary monitoring of post-deploy health across pages and routes
  • Baseline capture using screenshots and performance data
  • Alerting when anomalies are detected and targeted remediation guidance

Quick Start

Invoke /canary <url> to start a 10-minute health check of your deployed site, capturing baselines and screenshots.

Frequently Asked Questions about canary

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I monitor production for console errors after a deployment?

Post-deploy monitoring checks production health by watching live apps for console errors, performance regressions, and page failures using the browse daemon. It captures optional baselines and screenshots to detect anomalies.

What is visual canary monitoring for post-deploy verification?

Visual canary monitoring is a post-deploy verification technique that captures screenshots and performance data across pages and routes to establish baselines. It alerts you when live production traffic shows visual or performance anomalies.

Can I use post-deploy health checks to detect performance regressions across multiple routes?

Yes, post-deploy health checks monitor production across pages and routes to detect performance regressions. The browse daemon captures baseline performance data and screenshots to identify anomalies after deployment.

How do I start a health check for my deployed site?

To start a health check, invoke the canary command with your target URL. This initiates a 10-minute monitoring session that captures baselines and screenshots to verify production health.

Does canary monitoring require Bash tooling for production alerts?

Yes, canary monitoring requires Bash tooling and read/write capabilities to run post-deploy verification. It integrates with an AskUserQuestion workflow to handle alerting and remediation decisions.

What is the best way to set up automated baselines for post-deploy anomaly detection?

Automated baselines for post-deploy anomaly detection are set up by capturing screenshots and performance data during a health check. The browse daemon compares live production states against these baselines to trigger alerts.
