Using the Linux monitoring Grafana dashboard General /Kubernetes / Compute Resources / Namespace (Workloads)
that is showing total memory allocation in a sever, by default, you cannot switch between nodes (build/query) and check the total load of Build or Query servers separately.
Solution:
1 Edit the dashboard
2. Add new Variable
3. see settings
query: label_values(kube_node_info, node)
4. Edit Memory Usage Widget
5. add filter by node
node=~"$node"
Now you should be able to switch between nodes
