Azure Monitor allows you to set up alerts for various Azure resources and send the alert data to various destinations. While Azure Monitor does not directly support sending alerts to an application endpoint or a Service Bus, there are ways to achieve this
Option 1: Logic App
You can use Azure Logic Apps as an intermediary to receive the alert and then either invoke your application endpoint (via an HTTP action) or send a message to the Service Bus. Here are the steps to set it up:
Option 2: Azure Function
Similarly, you can create an Azure Function that is triggered by an HTTP request. The function could then call your application endpoint or send a message to the Service Bus.
