Linkerd View ServerAuthorization

Hi, is there a way to view a allow/deny traffic from source to destination on viz dashboard or CLI?

For example, we have applied Server profile and ServerAuthorization policy to service A, B & C. Service A & B are located in namespace X and service C is located in namespace Y. The policy attached to service C is only allowed service A. So, the policy will block when service B talks to service C. We would like to visualize or proof that the policy clearly deny the traffic from service B which is useful for troubleshooting or investigation.

Yes, check out the linkerd viz authz command. You can see some examples of how to use this command in this tutorial.
