SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy monitoring helps teams detect regressions quickly by validating production behavior after changes, ensuring reliability and user satisfaction.

Core Features & Use Cases

  • Continuous monitoring of a deployed URL for HTTP health, console errors, and performance regressions.
  • Supports quick check, sustained watch, and diff mode to compare environments.
  • Integrates with alerting to notify when critical thresholds are crossed.

Quick Start

Start a canary-watch session against your URL to begin monitoring.

FAQPage Schema
How do I monitor a deployed URL for post-deploy regressions?

To monitor a deployed URL for post-deploy regressions, start a canary-watch session to continuously check HTTP health, console errors, and performance against a baseline. It uses a polling loop to detect availability and content changes after production releases.

What is post-deploy monitoring and when do I need it?

Post-deploy monitoring validates production behavior after changes to ensure reliability. You need it after production releases, merges, or dependency upgrades to quickly detect regressions spanning performance, availability, and content checks before users are impacted.

Can I compare two environments to detect performance regressions?

Yes, you can compare environments to detect regressions using diff mode. This mode allows you to monitor a deployed URL and contrast its behavior against a baseline environment to identify performance, availability, and content discrepancies after a deploy.

How do I set up alerts for availability and performance thresholds?

You can set up alerts for availability and performance thresholds by integrating canary-watch into your existing post-deploy workflows. The monitoring loop crosses critical alert thresholds and triggers optional notifications to notify you when regressions occur.

Does post-deploy monitoring work for dependency upgrades and merges?

Yes, post-deploy monitoring works for dependency upgrades, merges, and production releases. The monitoring session validates HTTP health and performance regressions across web services, ensuring reliability regardless of the type of deployment change.

What is the best way to automate regression detection after a production release?

The best way to automate regression detection after a production release is running a sustained polling loop against your deployed URL. This continuously monitors HTTP health, console errors, and performance, alerting you when critical thresholds are crossed.
