As discussed a few times over the years, it's quite difficult to know how often we stop accepting connections because the global maxconn was reached. This is not easy to know because when we reach the limit we stop accepting but we don't know if incoming connections are pending, so it's not possible to know how many were delayed just because of this. However, an interesting equivalent metric consist in counting the number of times an accepted incoming connection resulted in the limit being reached. I.e. "we've accepted the last one for now". That doesn't imply any other one got delayed but it's a factual indicator that something might have been delayed. And by counting the number of such events, it becomes easier to know whether some limits need to be adjusted because they're reached often, or if it's exceptionally rare. The metric is reported as a counter in show info and on the stats page in the info section right next to "maxconn".
