Set alerts in a Resource Group
Currently there is no option to set alerts to control or monitor expenses in a subscription by a Resource Group. So, you have to set alerts in each VM and other resources you have.
Normally, if you manage all resources of a client (or concret environment) in a Resource Group, It would be very useful to control or monitor the expenses by alert configuring at the Resource Group level.
I would also like to see spending limits at the resource group level
