Visualize inter-az traffic

[omerh]

Describe the solution you'd like
Looking for a simple way to visualize inter-az traffic between pods and services. Pods availability zone can be added from the node label that the pod in running on.

Additional context
To have the same px/cluster view but with annotation of the AZ of the source and target

As additional context, sometimes interzonal traffic has a cost associated with it.
And sometimes topology-aware traffic routing is required to minimize latency.
Users who make these considerations would like to observe what happens in practice.
A visualization which shows which services/pods communicate across zones can be of great value for these use-cases.
