SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps teams catch issues early by watching live app behavior, collecting screenshots, and comparing baselines to detect regressions such as console errors, performance dips, and page failures.

Core Features & Use Cases

Post-deploy monitoring and anomaly alerts
Periodic screenshots and baseline comparisons to detect regressions
Alerts when anomalies are detected to trigger rapid investigations

Quick Start

Launch the canary monitor on your live app to start collecting baselines, screenshots, and alerting on anomalies.

FAQPage Schema

How do I monitor my production application for post-deploy regressions?▼

Post-deploy monitoring watches your live application for errors, latency spikes, and page failures. It collects baseline data and periodic screenshots to detect regressions and alert on anomalies.

What is canary monitoring and how does it detect production issues?▼

Canary monitoring detects production issues by continuously watching live application behavior. It compares current performance against established baselines to identify console errors, latency spikes, and page failures.

Do I need baseline data to start post-deploy monitoring?▼

Yes, baseline data is required to start post-deploy monitoring. The system uses these baselines to compare live application behavior and trigger automated anomaly alerts when regressions occur.

Can I use canary monitoring to get automated alerts for latency spikes?▼

Yes, canary monitoring provides automated anomaly alerts for latency spikes. It uses configurable alert thresholds to compare live application behavior against baselines and trigger rapid investigations.

What's the best way to catch console errors after a production deployment?▼

Continuous post-deploy monitoring catches console errors by watching the live application and comparing against baselines. It captures periodic screenshots and alerts you when anomalies are detected.

Are there limitations to using canary monitoring for multiple deployments?▼

Canary monitoring supports multiple environments and deployments but requires a browse daemon, baseline data, and configurable alert thresholds to operate effectively across all of them.
