Provided tutorial was updated 2 years ago.
Current version of Kubernetes is 1.17. As per tags, tutorial was tested on Prometheus v. 1.3.0, Kubernetes v.1.4.0 and Grafana v.3.1.1 which are quite old at the moment.
In requirements you have statement:
Prometheus will use metrics provided by cAdvisor via kubelet service (runs on each node of Kubernetes cluster by default) and via kube-apiserver service only.
In Kubernetes 1.16 metrics labels like pod_name and container_name was removed. Instead of that you need to use pod and container. You can verify it here.
Any Prometheus queries that match
pod_nameandcontainer_namelabels (e.g. cadvisor or kubelet probe metrics) must be updated to use pod and container instead.
Please check this Github Thread about dashboard bug for more information.
Solution
Please change pod_name to pod in your query.
Kubernetes version v1.16.0 has Removed cadvisor metric labels pod_name and container_name to match instrumentation guidelines. Any Prometheus queries that match pod_name and container_name labels (e.g. cadvisor or kubelet probe metrics) must be updated to use pod and container instead.
