No data for "App cost by pod" panel in grafana example dashboard

[thiDucTran]

I imported the dashboard @ https://github.com/opencost/opencost-helm-chart/blob/main/examples/dashboard/kube-prometheus-stack-opencost-dashboard.json to Grafana (kube-prometheus stack)

Seems metrics related to pods or containers are not showing

I tried editing some existing panel to use kube_node_labels{job="opencost"} instead of just kube_node_labels as commented in #9 (comment) but does not seem to fix anything

• AKS: v1.25
• quay.io/kubecost1/kubecost-cost-model:prod-1.105.1
• kube-prometheus v0.12.0

Am I doing something wrong because the metrics, container_memory_allocation_bytes and container_cpu_allocation, do not have the exported_container label...they do have a container label....so if I edit to something like below...I do then see data in the panel

  (sum(sum(container_memory_allocation_bytes{exported_namespace=~"$namespace", container=~"$app.*"}) by (container,exported_instance) * on(exported_instance) group_left() (
				node_ram_hourly_cost{} / 1024 / 1024 / 1024
				+ on(node,instance_type) group_left()
					label_replace
					(
						kube_node_labels{job="opencost"}, "instance_type", "$1", "label_node_kubernetes_io_instance_type", "(.*)"
					) * 0
			)
  + 
  sum(container_cpu_allocation{exported_namespace=~"$namespace", container=~"$app.*"}) by (container,exported_instance) * on(exported_instance) group_left() (
	  			node_cpu_hourly_cost{} + on(node,instance_type) group_left()
		  			label_replace
		  			(
		  				kube_node_labels{job="opencost"}, "instance_type", "$1", "label_node_kubernetes_io_instance_type", "(.*)"
		  			) * 0
		  	))) * 24 * 30

If someone with more Grafana experience wants to weigh in, I'm sure we'd appreciate a PR to fix this.

Checking the prometheus metrics it seems to just have a wrong label applied as you suspected @thiDucTran so the Prom query is failing. Other panels in the example dashboard don't have this problem, I can submit a PR on it
