Description

Auto-Healing is a mitigation action that can be taken when an app is having unexpected behavior. It can be triggered based on request count, slow request, memory limit, and HTTP status code.

It has been implemented on both resources azurerm_windows_web_app & azurerm_windows_web_app_slot but not on azurerm_windows_function_app & azurerm_windows_function_app_slot.

Thanks @JamesDLD for raising this issue, let me check this feature first. Once confirmed, I'll add it to our backlog.

It would be also nice to have support added to the azurerm_linux_function_app resource.
