@newxan

refer to number of connections if I have the setting type = "connections" or does it refer to number of requests?

Yes

Feature preview: Custom metrics

proxy_id - is to make sure the counters reset when we deploy or else it leads to some weird metrics. It’s possible we can have 2 proxies running concurrently while we gracefully shut down connections during a deploy. fly_app_concurrency - this is the current number of connections (or requests, depending on your concurrency config) established to your app instance
