Tell us about your request
It would be great if AppRunner could either publish some kind of event whenever it disconnects a client due to its request timeout of 120 seconds (as of 2024 - see also #104), or if it could at least publish metrics on how often it did so. Ideally, these metrics should be shown in the Metrics panel of the AppRunner console.

Describe alternatives you've considered
As far as I can tell, the only way we are able to figure out if something got disconnected due to AppRunner itself vs e.g. a client disconnecting from their end is to look at the time the request took before it was disconnected - if it's around 120 seconds, it was probably done by AppRunner. This isn't very convenient or exact, though.
