AWS Elastic Kubernetes Service

Metrics

Metricbeat is an open source shipping agent that lets you ship AWS Elastic Kubernetes Service (EKS) Metrics to one or more destinations, including Logstash.

Install Integration

Prerequisites

Firstly Make sure you have the aws cli, eksctl & kubectl installed on local machine using the following guide (opens in a new tab).

Also make sure you have setup aws configure with your AWS credentials.

To do this run run the following command in your aws terminal.

aws configure

When you type this command, the AWS CLI prompts you for four pieces of information: access key, secret access key, AWS Region, and output format. This information is stored in a profile named default. This profile is used when you run commands, unless you specify another one.

Connecting to the cluster

Update your config by running the following command. Replace <enter_region> and <enter_name> with your AWS cluster region and name.

aws eks --region <enter_region> update-kubeconfig --name <enter_name>

Check you can connect to your cluster by running the following command:

kubectl get svc

kube-state-metrics

You will need an instance of kube-state-metrics running on your cluster before you install metricbeat.

Cloning the kube-state-metrics repository locally and applying the example is the easiest way to generate some metrics. You can tailor these to your needs at a later stage.

git clone https://github.com/kubernetes/kube-state-metrics.git

Change into the newly downloaded directory:

cd go/src/k8s.io/kube-state-metrics/

Then to deploy this project, you can simply run:

kubectl apply -f examples/standard

Deploy Metricbeat

You're going to need the metricbeat deployment manifest.

curl -L -O cdn.logit.io/metricbeat-kubernetes-7.10.0.yaml

Now you have the manifest we need to add your Stack Logstash endpoint details. Open the file in the terminal editor using the vim or nano command. Alternatively you can choose Open Editor from the console toolbar to make your changes.

vi metricbeat-kubernetes-7.10.0.yaml

or

nano metricbeat-kubernetes-7.10.0.yaml

Update the following lines in the yaml with your Stack Logstash endpoint and Beats-SSL port.

env:
  - name: LOGSTASH_HOST
    value: "guid-ls.logit.io"
  - name: BEATS_PORT
    value: "00000"

After updating the code should look as below.

env:
  - name: LOGSTASH_HOST
    value: ["@logstash.host"]
  - name: BEATS_PORT
    value: ["@logstash.sslPort"]

Exit and save the file.

Apply your updates

Now we're going to apply the file to the cluster.

kubectl apply -f metricbeat-kubernetes-7.10.0.yaml

Confirm Deployment

Confirm your pod has deployed, you should see output similar to that below.

kubectl get po -A

or

kubectl logs ["podname"] --namespace=kube-system

Browse to Kibana and you should see Metrics arriving in your Stack.

Check Logit.io for your metrics

Data should now have been sent to your Stack.

If you don't see take a look at How to diagnose no data in Stack below for how to diagnose common issues.
