Collect Hub metrics
Introduction¶
You will learn how to use kubectl port-forward to connect to a Pod running the Traefik Hub Agent and how to use curl to
send a request to the /metrics endpoint.
Metrics¶
The endpoint will provide base metrics for:
- Status codes
- Response times
- Number of calls
Before you begin¶
You should have access to a working Kubernetes cluster, either on a cloud provider or on your own infrastructure.
This tutorial assumes that you have the Hub Agent and already installed following the installation tutorial.
1. Viewing and finding resources¶
In the first step, you will list all Container images of the traefik or ingress-nginx namespace. To target only pods in a specific namespace, use the namespace flag.
kubectl get pods -n traefikkubectl get pods -n ingress-nginxOn a basic example cluster the output will show for example:
NAME READY STATUS RESTARTS AGE
traefik-8f4dd6d84-9lr9g 2/2 Running 2 (40m ago) 40mNAME READY STATUS RESTARTS AGE
ingress-nginx-controller-75fd9b7589-bngn6 2/2 Running 3 (9m23s ago) 9m49sNote
The name of the Container image in your cluster may look different.
2. Forward a local port to a port on the Pod¶
kubectl port-forward allows using a resource name, such as a Pod name, to select a matching Pod to port forward to.
kubectl port-forward pods/traefik-8f4dd6d84-9lr9g -n traefik 8888:9001kubectl port-forward pods/ingress-nginx-controller-75fd9b7589-bngn6 -n ingress-nginx 8888:9001The output is similar to this:
Forwarding from 127.0.0.1:8888 -> 9001
Forwarding from [::1]:8888 -> 9001Note
kubectl port-forward does not return.
To continue with the exercise, you will need to open another terminal.
3. Sending API requests¶
In the last part of this tutorial, you will use curl to interact with the /metrics endpoint.
The following command will perform the request and output the response body:
curl http://localhost:8888/metricsWhich will show the metrics in Prometheus data format.
