"Running Pods" and "Running Container" metrics are not displayed on Grafana

Hi,

As you can see in my screenshot, I have trouble with displaying metrics on Grafana. "Running Pods" and "Running Container" metrics about Kubelet are not displayed on Grafana.

What happened: "Running Pods" and "Running Container" display N/A.

What you expected to happen: Actual values ​​will be displayed in "Running Pods" and "Running Container" on Grafana.

How to fix: Kubelet v1.19 following metrics have been renamed: #92407

kubelet_running_container_count --> kubelet_running_containers
kubelet_running_pod_count --> kubelet_running_pods

I think that ConfigMap data which is named "grafana-dashboard-k8s-resources-workloads-namespace" in manifests/grafana-dashboardDefinitions.yaml needs to revise.

Environment:

• Kubernetes version (use kubectl version): 1.19.4
• Hardware: Raspberry Pi 4
• OS (e.g: cat /etc/os-release): Ubuntu 20.04.1 LTS (Focal Fossa)
• Kernel (e.g. uname -a): Linux 5.4.0-1023-raspi aarch64 GNU/Linux
• Install tools: kubeadm 1.19.4
• Others: Kubelet version: 1.19.4
