Thanks for the suggestion, but with it slow progression and low
signal-to-noise ration in comparison with the daily and weekly
connection cycle, I'm not sure it would be practically possible to
measure it like that. But your suggestion gave me another idea, to
record IPs of established tcp conns every 5 minutes and then see which
ones remain constant.
But are you suggesting that nginx status is reporting wrong/fake
numbers? What do you mean by "real"?
And what about connections that are staying in "CLOSED" state until I
restart or reload nginx?
