can't reliably fetch stats when using SO_REUSEPORT
I'm using knot resolver with systemd, and want to use the stats module + http module to fetch stats in prometheus format.
My problem is that if I start more that one instance (kresd@1, kresd@2, …), stats fetching requests are distributed among the instances and returns only the stats from the answering instance.
I can't get a reliable way to fetch the stats in such configuration.
Workaround: I can fetch and aggregate individual workers stats from the controls sockets, but the control socket is very unreliable (it is not able to properly parse 2 successives queries properly and often try to interpret them as a single query).
