Please see the guide below to fix the issue!

This will work as long as you have both your Grafana and Prometheus running as a docker images so before you begin please run the command below to be sure that both prom and Grafana images are up

docker ps

To connect the prometheus to GRAFANA, you will need to get the prometheus server IP address that is running as a docker image from host.

Use this command on your terminal to display all the container IDs:

docker ps -a

You will see your prometheus server container ID displayed for example "faca0c893603". Please copy the ID and run the command below on your terminal to see the IP address of your Prometheus server:

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' faca0c893603

Note : (faca0c893603 is the ContainerID of the prom/prometheus server)

When you run the command it will display the IP address(172.17.0.3) of the Prometheus container which needs to be mapped with the port of the prometheus server on Grafana.

On data source on Grafana, put this on the URL http://172.17.0.3:9090 and try to save and test.

It looks like you are pointing towards the node exporter endpoint and not Prometheus Server. The default Prometheus Server endpoint is 9090. Try change your source to http://192.168.33.22:9090

Grafana doesn't query Node Exporter directly, it queries Prometheus Server which gathers the time series statistics.
