PromQL Question/Help

[RB]

Hello,

I’m in the process of migrating some apps from amd64 to arm64 instances and was looking for help/guidance on a particular query to create a grafana dashboard.  What I’m trying to accomplish is displaying the number of pods running on a node by particular instance type/architecture.  The Karpenter “Pod Distribution by Instance Type” dashboard is what I’m trying to emulate.  We are not using Karpenter, so can’t use the promql expression they are using.

I did find this issue where someone tried to join kube_pod_labels with kube_node_labels.  I modified kube_state_metrics –metrics-allowlist to add the node.kubernetes.io instance_type and tried the following promql, but received a many-to-many matching not allowed Error:

kube_pod_info * on(pod,namespace) group_right(node) kube_pod_labels * on(node) group_left(label_kubernetes_io_instance_type) kube_node_labels

 Any help or guidance with this would be greatly appreciated.

 

Thanks,

Ron
