Overview

Get metrics from Ambassador in real time to:

• Visualize the performance of your microservices

• Understand the impact of new versions of your services as you use Ambassador to do a canary rollout

Setup

By default, Ambassador installs a statsd sidecar on its pod. This sidecar forwards statsd metric to any Kubernetes service named statsd-sink.

1. Create a file datadog-statsd-sink.yaml with the following configuration, replacing the API key below with your own API key:

   ---
   apiVersion: apps/v1
   kind: Deployment
   metadata:
    name: statsd-sink
   spec:
     selector:
       matchLabels:
         service: statsd-sink
    replicas: 1
    template:
      metadata:
        labels:
          service: statsd-sink
      spec:
        containers:
        - name: statsd-sink
          image: datadog/docker-dd-agent:latest
          ports:
            - containerPort: 8125
              name: dogstatsdport
              protocol: UDP
          env:
            - name: API_KEY
              value: "<YOUR_DATADOG_API_KEY>"
            - name: KUBERNETES
              value: "yes"
            - name: SD_BACKEND
              value: docker
        restartPolicy: Always
   status: {}
   ---
   apiVersion: v1
   kind: Service
   metadata:
    labels:
      service: statsd-sink
    name: statsd-sink
   spec:
    ports:
       - protocol: UDP
         port: 8125
         name: dogstatsdport
    selector:
      service: statsd-sink
   

2. Deploy the agent to Kubernetes:

   kubectl apply -f datadog-statsd-sink.yaml
   

3. As soon as some traffic flows through Ambassador, your metrics should appear.
