Does it support PSR standards?

Yes, it includes a PSR-15 compliant middleware for automated metric collection and integrates easily with PSR-7/PSR-17 request/response interfaces.

What metrics does the RED pattern track?

The RED pattern tracks Rate (total requests), Errors (failed requests based on status codes), and Duration (time taken to process requests).

How do I test code that uses these metrics?

The skill generates a NullMetricsCollector, which follows the Null Object pattern. This allows you to inject a no-op collector in your unit tests to avoid external dependencies.

Is this skill compatible with modern PHP versions?

Yes, it is specifically designed for PHP 8.4, utilizing modern features like readonly classes and constructor property promotion.

Does it require a specific monitoring backend?

No. While it includes a Prometheus adapter, the architecture is backend-agnostic, allowing you to swap in other providers like StatsD via the MetricsCollectorInterface.

Analytics & Monitoring

Generates robust metrics collection infrastructure for PHP 8.4 applications including Prometheus integration and RED metrics middleware.

The create-metrics-collector skill automates the creation of a comprehensive observability layer for modern PHP applications using industry-standard patterns like the RED (Rate, Errors, Duration) framework. It provides a backend-agnostic interface with specific wrappers for Counters, Gauges, and Histograms, alongside a PSR-15 middleware for automatic request tracking. Built for PHP 8.4, this skill helps developers implement production-ready Prometheus monitoring while maintaining clean architecture principles and ensuring testability through integrated Null Object patterns.
