SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy monitoring to detect and alert on production regressions, reducing mean time to detect deployment issues.

Core Features & Use Cases

  • Baseline capture before deployment to establish a healthy reference.
  • Post-deploy monitoring that compares live app behavior against the baseline and raises alerts when regressions occur.
  • Health reporting with per-endpoint status and automated canary reports for post-release visibility.

Quick Start

Run the canary baseline capture to establish a healthy baseline, then start monitoring the deployed application for regressions.

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

To monitor for production regressions, you can capture a healthy baseline before deploy and then compare live application behavior against it to raise alerts when issues occur. This reduces mean time to detect deployment problems.

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

Post-deploy canary monitoring is the process of comparing live application behavior against a pre-deploy baseline to detect regressions. You need it when rolling out new releases to production to quickly identify deployment-related health issues.

How do I establish a health baseline before deploying my application?▼

You establish a health baseline by running a baseline capture process that records your application's healthy reference state. This baseline is stored under the .canary/baselines directory for later comparison during post-deploy monitoring.

Can I get per-endpoint health reporting for my live application after release?▼

Yes, post-deploy monitoring provides health reporting with per-endpoint status. It compares live app behavior against the stored baseline and generates automated canary reports for post-release visibility.

Do I need configurable health checks to use post-deploy monitoring?▼

Yes, configurable health checks are required to identify post-deploy regressions in production. You must configure these health checks and alerting rules to report issues when comparing live behavior against the stored baseline.

What are the limitations of baseline comparison for post-deploy alerting?▼

Baseline comparison alerting requires a pre-deploy capture phase to establish the reference baseline. Without a captured baseline stored under .canary/baselines, the monitoring mode cannot compare live application behavior to detect regressions.
