Headlamp cluster metrics are not showing the proper values
Hello, i am a new user, i really liked the project.
I am having some problems with the cluster wide metrics that are show on the dashboard:
I am using kube-prometheus-stack to handle prometheus and grafana and i am using prometheus-adapter for the metrics API.
To get the headlamp to even show anything i had to add a few settings to the chart's values:
kube-prometheus-stack
kubelet:
serviceMonitor:
metricRelabelings:
- action: replace
sourceLabels:
- node
targetLabel: instance
prometheus-node-exporter:
prometheus:
monitor:
attachMetadata:
node: true
relabelings:
- sourceLabels:
- __meta_kubernetes_endpoint_node_name
targetLabel: node
action: replace
regex: (.+)
replacement: ${1}
metricRelabelings:
- action: replace
regex: (.*)
replacement: $1
sourceLabels:
- __meta_kubernetes_pod_node_name
targetLabel: kubernetes_node
prometheus-adapter (which is normal to get the metrics apis)

)

Individual node's CPU values are correct, the memory value is correct as well but the unit is different:
Is this a headlamp problem or this a prometheus(me) problem?
Thanks for the help and the project have a nice day.
