Datadog Quickstart Guide

This quickstart guide will help you get Causely up and running with Datadog. This setup uses Datadog APM with dual shipping to send traces to Causely while continuing to send data to Datadog.

1

Get Your Installation Command​

  1. Log in to the Causely portal.
  2. Visit the mediators page.
  3. Click the "Add new" button (or "Add ➕" button) on the mediators page.
  4. In the instructions panel, you'll see the Helm installation command with your access token pre-filled.
  5. Copy the complete Helm command. It will look similar to the example below.
Example Command

The command you copy will include your specific access token and cluster name. Here's what it typically looks like:

export CAUSELY_TOKEN=<your_token>
export CAUSELY_CLUSTER_NAME=<your_cluster_name>
export CAUSELY_VERSION=<version>
helm upgrade --install causely \\
  --create-namespace oci://us-docker.pkg.dev/public-causely/public/causely \\
  --version "${CAUSELY_VERSION}" \\
  --namespace=causely \\
  --set image.tag="${CAUSELY_VERSION}" \\
  --set global.cluster_name="\${CAUSELY_CLUSTER_NAME}" \\
  --set mediator.gateway.token="\${CAUSELY_TOKEN}"

Screenshots of the mediators page, "Add new" button, and instructions panel will be added here.

Create a Values File to Disable eBPF​

Since you'll be using Datadog for instrumentation, create a causely-values.yaml file to disable eBPF instrumentation:

global:
  cluster_name: <your_cluster_name>
mediator:
  gateway:
    token: <your_token>
scrapers:
  bpf:
    enabled: false

Replace <your_cluster_name> and <your_token> with your actual values from the portal.

5

Run the Installation Command​

  1. Open a terminal with kubectl configured to access your cluster.
  2. Run the Helm command with your values file:
export CAUSELY_VERSION=<version>
helm upgrade --install causely \\
  --create-namespace oci://us-docker.pkg.dev/public-causely/public/causely \\
  --version "${CAUSELY_VERSION}" \\
  --namespace=causely \\
  --set image.tag="${CAUSELY_VERSION}" \\
  --set global.cluster_name="<your_cluster_name>" \\
  --set mediator.gateway.token="<your_token>" \\
  --values causely-values.yaml
  1. Wait for the installation to complete:
kubectl wait --for=condition=Ready pod -l app.kubernetes.io/part-of=causely -n causely --timeout=300s
6

Configure Datadog Dual Shipping​

Now you need to configure your Datadog Agent to send traces to Causely using dual shipping.

Option 1: If using Helm to deploy Datadog​

Add the following to your Datadog values.yaml:

agents:
  useConfigMap: true
  customAgentConfig:
    apm_config:
      additional_endpoints:
        'http://mediator.causely:8126':
          - 'datadog-receiver'

Then upgrade your Datadog installation:

helm upgrade --install datadog datadog/datadog -f ./values.yaml

Option 2: If using the Datadog Operator​

Modify your DatadogAgent custom resource:

apiVersion: datadoghq.com/v2alpha1
kind: DatadogAgent
metadata:
  name: datadog
spec:
  override:
    nodeAgent:
      env:
        - name: DD_APM_ADDITIONAL_ENDPOINTS
          value: '{"http://mediator.causely:8126": ["datadog-receiver"]}'

For more details, see the Datadog integration documentation.

What to Expect​

Once configured, Causely will:

  • Receive Datadog traces: Your Datadog Agent will send traces to Causely's mediator via dual shipping.
  • Discover service dependencies: Causely will automatically discover service dependencies from your Datadog APM traces.
  • Show data in the UI: Within a few minutes, you should start seeing services and their relationships appearing in the Causely UI at https://portal.causely.app.
tip

You can also enable Datadog monitors as a data source for additional insights. See the Datadog integration documentation for details.

Add More Telemetry Sources​

To help Causely identify root causes more effectively, connect additional telemetry sources. Visit the Telemetry Sources page to learn about the data sources that Causely supports, including:
