Import path: github.com/InsideGallery/core/metrics/processors/datadog

This package registers the Datadog DogStatsD metrics processor. It sends count, gauge, and distribution metrics through github.com/DataDog/datadog-go/v5/statsd.

Main APIs

• ProcessorName is the registration name: datadog.
• New(cfg metrics.Config, service string) creates the processor and is registered from init.

Usage

package main

import (
	_ "github.com/InsideGallery/core/metrics/processors/datadog"

	"github.com/InsideGallery/core/metrics"
)

func newMetrics() (*metrics.Client, error) {
	cfg, err := metrics.GetEnvConfig()
	if err != nil {
		return nil, err
	}

	return metrics.New(cfg, "api")
}

Run with METRICS_PROCESSORS=datadog and configure an address.

Configuration

The package reads the METRICS_DATADOG prefix:

• METRICS_DATADOG_ADDR: DogStatsD address. Required unless DD_STATSD_ADDR is set.
• METRICS_DATADOG_NAMESPACE: metric namespace, default ptolemy.
• DD_STATSD_ADDR: legacy fallback address when METRICS_DATADOG_ADDR is blank.

The namespace is trimmed and normalized to include one trailing dot. The processor adds a service:<service> tag at client construction and forwards per-metric tags unchanged.

Live integration tests require PTOLEMY_METRICS_DATADOG_INTEGRATION=1 and one address variable.
