What problem does it solve?

Domain events and API endpoints often lack structured, business-focused observability. This skill provides a principled way to emit AWS CloudWatch Embedded Metric Format (EMF) metrics from domain events to illuminate business KPIs instead of relying solely on infrastructure metrics.

Core Features & Use Cases

  • Typed, domain-specific metrics emitted via event subscribers (not hardcoded in handlers)
  • EMF-formatted logs that CloudWatch can extract as metrics
  • SOLID architecture with dedicated metric classes, dimension handling, and an emitter
  • Supports single metrics and MetricCollection for batching multiple metrics

Quick Start

Emit a typed EMF metric from a domain event using a dedicated event subscriber.
