Información general

k6 es una herramienta de pruebas de carga de código abierto que te ayuda a detectar antes los problemas de rendimiento y las regresiones.

Con la integración de k6, puedes realizar un rastreo de las métricas de rendimiento de tests de k6 para:

Correlacionar el rendimiento de la aplicación con las métricas de tests de carga.
Crear alertas basadas en métricas de tests de rendimiento.
Analizar y visualizar métricas de k6 utilizando el dashboard de k6 Datadog o el Metrics Explorer.

Instalación

En Datadog, ve a integraciones > API para copiar tu clave de API.

Ejecuta el Datadog Agent:

Para llevar métricas de k6 a Datadog, k6 envía métricas a través del Datadog Agent, que recopila, agrega y reenvía métricas a la plataforma de Datadog.

Ejecuta el servicio del Datadog Agent como contenedor de Docker con este comando:

DOCKER_CONTENT_TRUST=1 \
docker run -d \
    --name datadog \
    -v /var/run/docker.sock:/var/run/docker.sock:ro \
    -v /proc/:/host/proc/:ro \
    -v /sys/fs/cgroup/:/host/sys/fs/cgroup:ro \
    -e DD_SITE="datadoghq.com" \
    -e DD_API_KEY=<YOUR_DATADOG_API_KEY> \
    -e DD_DOGSTATSD_NON_LOCAL_TRAFFIC=1 \
    -p 8125:8125/udp \
    datadog/agent:latest

Nota: Sustituye <YOUR_DATADOG_API_KEY> por tu clave de API. Si tu cuenta está registrada con Datadog EU, cambia el valor de DD_SITE por datadoghq.eu.

Ejecuta el test de k6 y envía los resultados a Datadog.
Una vez que el servicio del Datadog Agent esté funcionando, ejecuta el test de k6 y envía las métricas al Agent con:
```
K6_STATSD_ENABLE_TAGS=true k6 run --out statsd script.js
```
Visualiza las métricas de k6 en Datadog.
Mientras se ejecuta el test, k6 envía métricas periódicamente a Datadog. Por defecto, estas métricas tienen k6. como prefijo del nombre.
Puedes visualizar métricas de k6 en tiempo real con el Metrics Explorer, monitores, o dashboards personalizados.
k6 Datadog Metrics Explorer
Además, la primera vez que Datadog detecta la métrica k6.http_reqs, el cuadro de integración de k6 se instala automáticamente y el dashboard de k6 por defecto se añade a tu lista de dashboard.
