Datadog metrics adapter implementation using DogStatsD protocol.

This adapter integrates with Datadog (https://datadoghq.com) for production metrics collection via the DogStatsD UDP protocol. It implements all metrics protocols to provide comprehensive metrics capabilities that integrate with Datadog's platform.

Features:

• DogStatsD UDP protocol implementation
• Counter, gauge, histogram, and timing metrics
• Tag merging (global, metric default, call-specific)
• Sampling support for performance optimization
• Runtime metric enable/disable for performance tuning
• In-memory metric registry and value tracking
• Injectable send function for testability

Configuration: The adapter requires a host and service name, optionally accepting:

• Port (default 8125)
• Global tags applied to all metrics
• Sample rate for counters and histograms
• Maximum packet size (UDP MTU considerations)
• Origin detection for container environments

Example: (def datadog-metrics (create-datadog-metrics-components {:provider :datadog-statsd :host "localhost" :port 8125 :service "my-service" :environment "production" :global-tags {:team "backend" :version "1.0.0"} :sample-rate 0.1 :max-packet-size 1432}))

create-datadog-metrics-component clj

(create-datadog-metrics-component config)

Create a complete Datadog metrics component that implements all protocols.

This is the recommended way to create Datadog metrics for use with Integrant.

create-datadog-metrics-components clj

(create-datadog-metrics-components config)

Create a map of Datadog metrics components for Integrant system configuration.

Returns a map with keys:

• :metrics-registry - IMetricsRegistry implementation
• :metrics-emitter - IMetricsEmitter implementation
• :metrics-exporter - IMetricsExporter implementation
• :metrics-config - IMetricsConfig implementation

create-datadog-metrics-config clj

(create-datadog-metrics-config config registry)

Create a Datadog metrics config instance.

create-datadog-metrics-emitter clj

(create-datadog-metrics-emitter registry config send-fn)

Create a Datadog metrics emitter instance.

create-datadog-metrics-exporter clj

(create-datadog-metrics-exporter registry config)

Create a Datadog metrics exporter instance.

create-datadog-metrics-registry clj

(create-datadog-metrics-registry config)

Create a Datadog metrics registry instance.
