Métricas de tiempo de ejecución de Node.js

Documentos > APM > Métricas de APM > Métricas de tiempo de ejecución > Métricas de tiempo de ejecución de Node.js

Esta función está en fase beta pública.

Configuración automática

La recopilación de métricas de tiempo de ejecución puede activarse con un parámetro de configuración en el cliente de rastreo, ya sea a través de la opción del rastreador: tracer.init({ runtimeMetrics: true }) o a través de la variable de entorno: DD_RUNTIME_METRICS_ENABLED=true

export DD_RUNTIME_METRICS_ENABLED=true
export DD_ENV=prod
export DD_SERVICE=my-web-app
export DD_VERSION=1.0.3

const tracer = require('dd-trace').init({
  env: 'prod',
  service: 'my-web-app',
  version: '1.0.3',
  runtimeMetrics: true
})

Las métricas de tiempo de ejecución se pueden ver en correlación con tus servicios de Node. Consulta el Catálogo de servicios en Datadog.

Por defecto, las métricas de tiempo de ejecución de tu aplicación se envían al Datadog Agent con DogStatsD en el puerto 8125. Asegúrate de que DogStatsD está habilitado para el Agent. Si estás ejecutando el Agent como un contenedor, asegúrate de que DD_DOGSTATSD_NON_LOCAL_TRAFFIC está configurado como true y que el puerto 8125 está abierto en el Agent. En Kubernetes, vincula el puerto de DogStatsD a un puerto host; en ECS, establece los indicadores apropiados en tu definición de tarea.

Alternativamente, el Agent puede ingerir métricas con un Unix Domain Socket (UDS) como alternativa al transporte UDP. Para más información, lee DogStatsD en Unix Domain Socket.
