💡 This Skill requires Bash, Read, Write, Glob, AskUserQuestion, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps monitor the health and performance of live apps after deployment, detecting errors, performance regressions, and page failures.

Core Features & Use Cases

  • Error Detection: Identifies console errors and alerts on anomalies.
  • Performance Monitoring: Compares periodic screenshots against pre-deploy baselines for performance regressions.
  • Use Case: Deploy this Skill to continuously monitor a live application for any issues that may arise post-deployment.

Quick Start

Monitor the post-deployment health of your app by running the canary skill.

Frequently Asked Questions about canary

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I monitor app health after a continuous deployment release?

To monitor app health after a continuous deployment release, you need post-deploy monitoring that detects console errors and performance regressions. This Skill automates that process by continuously checking live applications for post-deployment issues.

Can I detect performance regressions using screenshot comparison?

Yes, you can detect performance regressions using screenshot comparison. This Skill compares periodic screenshots against pre-deploy baselines to identify visual or performance anomalies that may arise after a release.

What is a canary release and when do I need post-deploy monitoring?

A canary release is a deployment strategy that gradually rolls out changes to a subset of users. You need post-deploy monitoring to trigger alerts for errors and regressions before the release reaches your entire user base.

Do I need Bash to run post-deployment error detection?

Yes, you need Bash to run post-deployment error detection, along with Read, Write, Glob, and AskUserQuestion tools. These dependencies are required to execute scripts and monitor application performance continuously.

How do I set up alerts for console errors in a live application?

To set up alerts for console errors in a live application, deploy a monitoring Skill that identifies anomalies and triggers alerts. This automates error detection within your continuous deployment pipelines.

What is the best way to automate post-deploy monitoring for app performance?

The best way to automate post-deploy monitoring for app performance is integrating a monitoring Skill into your continuous deployment pipelines. It detects errors and compares screenshots against baselines to catch regressions.
