SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Canary monitoring after deployment to catch production issues early by watching logs, performance, and visual regressions.

Core Features & Use Cases

  • Real-time post-deploy verification: monitors console errors, performance metrics, and page stability.
  • Baseline comparisons: compares against pre-deploy baselines and alerts on anomalies.
  • Visual and metrics snapshots: takes screenshots and captures timing data for dashboards.

Quick Start

Start a canary run on your URL for 10 minutes to begin monitoring production.

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

Post-deploy monitoring checks production reliability by watching console errors, performance metrics, and visual regressions. Canary performs these checks and compares against pre-deploy baselines to catch live app faults.

What is canary monitoring and when do I need it for my application?

Canary monitoring is the process of watching live production metrics, logs, and visuals immediately after a deployment. You need it to detect reliability issues and visual regressions early before they impact users.

How do I capture pre-deploy baselines for post-deploy comparisons?

Pre-deploy baselines are captured by taking initial screenshots and performance timing snapshots of selected pages. Canary compares these baseline metrics against live production data to alert on anomalies.

Does production monitoring work with specific page selection and duration limits?

Yes, production monitoring supports configurable page selection and continuous monitoring duration. You can target specific URLs and run a canary session for a set period, such as 10 minutes.

Why does my visual regression check fail after deploying to production?

Visual regression checks fail when live production screenshots differ from pre-deploy baselines. Canary monitors these visual snapshots alongside console errors and performance metrics to detect rapid faults.

What is the best way to verify application stability across console, performance, and visuals?

The best way to verify stability is continuous post-deploy monitoring that captures screenshots and timing data. Canary compares these metrics against baselines to alert on console, performance, and visual anomalies.
