Once the Resources are discovered from your Azure account, we also automatically bring in the tags associated with them, and show it up in our web client.
We create Monitor Groups at the Azure account level (Account level overview map). This will provide clear insights on the Subscriptions, the Resource Groups under each Subscription, and the Resources (with status) under each Resource Group. Currently, we don't create Monitor Groups based on Azure tags. We shall add this to our road map and update this thread when it's live.
