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: extensions/v1beta1
kind: Deployment
metadata:
 name: statsd-sink
spec:
 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.
