Thank you for your feedback. Unfortunately, we do not plan to add this feature to our platform at this time. We will provide an update if this changes. For any further questions, or to discuss your specific scenario, send us an email at email@example.com.
We understand this is a top customer ask and as such it is currently on our backlog to be prioritized. We will update when the status changes.
There is no plan currently to offer these system level metrics for Application Gateway Standard (V1). However, we are planning to offer more observability with our new Autoscaling version (V2) of Application Gateway/WAF. We already offer Capacity Units as a metric which gives you a sense of the traffic load on your Application Gateway. More are planned for V2.
