SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy monitoring is essential to catch issues that pass CI but fail in production, such as missing environment variables, cache issues, or slow migrations. This skill provides an automated, time-bounded post-deploy health check to detect regressions early and keep services reliable.

Core Features & Use Cases

  • Continuous post-deploy monitoring: Observe production behavior for a defined window to identify errors and performance regressions.
  • Baseline capture and comparison: Create baselines before or during deployment to detect drift and regressions.
  • Alert-driven health checks: Produce structured alerts (CRITICAL/HIGH/MEDIUM) with evidence like logs, timings, and screenshots, guiding quick remediation.
  • Use Case: After deploying a new release, run canary checks on the production URL to verify no critical issues appear within the first ten minutes.

Quick Start

Run /canary <url> to start a 10-minute canary monitor on the target production URL.

FAQPage Schema
How do I automate post-deploy canary checks to catch production issues?

Post-deploy canary checks are automated by actively monitoring a production URL for anomalies during the first 10 minutes after deployment to detect errors and performance regressions. The monitor observes live behavior to identify issues that passed CI checks.

What is a post-deploy monitoring baseline and how does it detect regressions?

A post-deploy monitoring baseline captures normal service behavior before or during deployment to detect drift. By comparing live production metrics against this baseline, the monitoring process identifies performance regressions and emerging errors immediately after the release.

How do I run a 10-minute canary monitor on a production URL?

To run a 10-minute canary monitor, execute the monitoring command with your target production URL. The automated health check then observes the live web service continuously for the defined window to verify no critical issues appear.

Does post-deploy monitoring work for catching issues that pass CI but fail in production?

Yes, post-deploy monitoring is specifically designed to catch issues that pass CI but fail in production. It actively observes live URLs to detect missing environment variables, cache issues, slow migrations, and other runtime anomalies that automated tests miss.

What types of structured health alerts are produced during production observability checks?

Production observability checks produce structured health alerts categorized as CRITICAL, HIGH, and MEDIUM. These alerts include remediation evidence such as logs, timings, and screenshots to guide quick resolution of detected post-deploy anomalies.

Can I configure the monitoring duration for post-deploy reliability checks?

Yes, post-deploy reliability checks feature configurable monitoring durations, with a default 10-minute window for immediate observation. This time-bounded approach ensures active monitoring captures early anomalies without indefinite resource consumption.
