⚠️   For k6 Cloud tests, follow the k6 Cloud instructions.

k6 can send metrics to Datadog. That allows visualizing and correlating performance testing metrics with other monitored metrics in Datadog.

This article outlines the instructions of the Datadog integration:

  • Run the Datadog Agent
  • Run the k6 test
  • Visualize in Datadog

Run the Datadog Agent

To get k6 metrics into Datadog, k6 sends metrics through the Datadog Agent, which collects, aggregates, and forwards the metrics to the Datadog platform.

Run the Datadog Agent service as a Docker container with this command:

docker run --rm -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="" \
-p 8125:8125/udp \

Replace <YOUR_DATADOG_API_KEY> with your Datadog API key.

If your account is registered with Datadog EU, change the value of DD_SITE to

For additional information, read the Datadog Docker Agent documentation.


The Datadog agent includes the DogStatsD service to collect and aggregate metrics. DogStatsD implements the StatsD protocol with some extensions. For example, DogStatsD tagging allows to collect k6 metrics with tags to distinguish between requests for different URLs, response statuses, groups, etc.

The instruction above runs the DogStatsD service in a Docker container, but it's also possible to run it either as Host Agent, Kubernetes, and Helm.

Run the k6 test

Once the Datadog Agent service is running, run the k6 test and send the metrics to the Agent with:

$ K6_STATSD_ENABLE_TAGS=true k6 run --out statsd script.js

Please look at the StatsD output page for configuration options.

Visualize in Datadog

While running the test, k6 sends metrics periodically to Datadog. By default, these metrics have k6. as the name prefix.

You can visualize k6 metrics in real-time with the metrics explorer, monitors, or custom dashboards.

The first time Datadog detects the k6.http_reqs metric, the k6 integration tile is installed automatically, and the default k6 dashboard is added to your dashboard list.

k6 Datadog Dashboard

Optionally, you can install the k6 integration tile following these instructions:

  1. Log in to Datadog.
  2. From the sidebar menu, choose Integrations > Integrations.
  3. Search for k6, then select the k6 integration.
  4. Click on the Configuration tab option.
  5. Scroll down and click on the Install integration button.
