I created several Azure OpenAI resources in my Azure account via https://portal.azure.com. How can I view at once the cost incurred by all my Azure OpenAI resources for the current month or the last 30 days? I don't want to have to check the cost for each resource one by one (example), especially since cost management pages on https://portal.azure.com takes a while to load.
Each resource is assigned to a subscription:
One can view the cost of all resources assigned to a subscription by going to https://portal.azure.com/#home, and clicking on the subscription name:
Subscriptions also have a cost management page, just like for resources:
One can view the breakdown by resource at the bottom right of the page.
