Load Balancer Types: Standard vs Basic

As a feature with Standard Load Balancers, Microsoft makes performance metrics available within the the API. The metrics listed below are only available at the Standard license level.

The Source will configure and collect property metrics with the Basic Load Balancer type.

Least Privileged User

Steps:

Using the Azure CLI Client, find the Subscription ID and Tenant ID from your account list
