I am trying to set up a mechanism to shut down my Azure Functions app if a cost alert gets thrown. I have created an automation account, a powershell runbook, and an action group. I went into Cost + Billing in for my tenant in azure and created a Cost Alert. I tried to associate the alert with an Action Group, but I couldn't find a way. I don't know if this was ever possible in the interface. Next I tried another way: I started setting up a Logic App to kick off when I receive the alert email but there is no "Free" cost plan. Is there a way to stop my app if a price threshold is met for free?
The "Manage Action Groups" link was not displayed becuase the context I was looking at in Billing was an account and not my subscription. When I changed to my subscription the link appeared on the "Set Alerts" tab.
