Detailed Description

Metric data exporters for various monitoring and observability systems.

This file provides exporters for popular metric collection systems:

• Prometheus (Pull-based metrics system with HTTP endpoint)
• StatsD (Push-based UDP metrics aggregation system)
• OpenTelemetry Metrics (OTLP metrics protocol)

Each exporter handles format conversion and protocol-specific transmission to the respective metrics backend.
