SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canaries help teams detect issues that do not surface in CI, by watching live applications for console errors, performance regressions, and page failures. This reduces the risk of undetected bugs slipping into production.

Core Features & Use Cases

  • Baseline capture and comparison against pre-deploy state to detect drift.
  • Page-level health checks with automated alerts on anomalies.
  • Deterministic, script-driven workflow that uses Bash, Read, Write, Glob, and AskUserQuestion to orchestrate monitoring tasks.

Quick Start

Start monitoring a deployed URL by invoking the canary with the URL to begin a fixed-duration observation.

FAQPage Schema
How do I monitor live web apps for console errors after a production deploy?

Post-deploy canary monitoring tracks live web pages for console errors, performance regressions, and page failures. It captures pre-deploy baselines and performs page-by-page health checks to catch production bugs that bypass CI.

What is a post-deploy canary baseline and how does drift detection work?

A canary baseline captures the pre-deploy state of live user flows. Drift detection compares post-deploy page health and performance metrics against this baseline to automatically alert on regressions.

How do I set up automated alerts for performance regressions in production?

Automated alerts for performance regressions are configured using a script-driven workflow. By capturing baselines and monitoring live URLs, the system orchestrates health checks and triggers alerts via Bash, Read, Write, and Glob.

Can I use script-driven monitoring for user flow health checks in production?

Yes, script-driven monitoring supports production deployments across web pages and user flows. It uses deterministic orchestration with Bash, Read, Write, Glob, and AskUserQuestion to execute baseline comparisons and deliver actionable alerts.

Do I need any external dependencies to run post-deploy canary checks?

No external dependencies are required. The canary workflow operates deterministically using available built-in tooling such as Bash, Read, Write, Glob, and AskUserQuestion to orchestrate monitoring tasks and alerts.
