SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Extended monitoring after deployment to catch issues that only manifest under real user traffic.

Core Features & Use Cases

  • Automated post-deploy checks run at regular intervals to verify production health.
  • Anomaly detection flags new console errors, network failures, performance regressions, and visual layout changes.
  • Evidence reporting outputs a concise health report and optional screenshots for quick triage.

Quick Start

Run the canary skill after deployment to start an automated post-deploy monitoring loop.

FAQPage Schema
How do I monitor production health after a web app deployment?

Post-deploy monitoring runs automated checks on real-user traffic to verify production health. It operates at a 2-5 minute cadence for up to 30 minutes to detect new console errors, network failures, and performance regressions.

What is automated post-deploy anomaly detection for web services?

Automated post-deploy anomaly detection identifies issues in production deployments under real-user traffic. It flags new console errors, network failures, performance regressions, and visual layout changes by running regular checks across multiple flows.

How do I detect performance regressions in production after releasing?

To detect performance regressions after releasing, run post-deploy monitoring checks on your web app. This process collects metrics during real-user traffic at regular intervals and flags any detected performance drops or anomalies.

Does post-deploy monitoring work for catching new console errors in web apps?

Yes, post-deploy monitoring works for catching new console errors in web apps. It performs regular checks during real-user traffic and explicitly reports new console errors alongside network failures and visual layout changes.

What are the limitations of automated post-deploy checks for production health?

Automated post-deploy checks are limited to a maximum duration of 30 minutes with a strict cadence of 2-5 minutes. They monitor real-user traffic on web apps and services but do not perform continuous long-term monitoring beyond this window.
