the upstream sources of >=net-proxy/haproxy-2.0.0 provide [1] the option to add a Prometheus Endpoint to scrape statistics from. This was first announced for the 2.0-dev branch [2] and is now officially supported by the final release of haproxy 2.0 TL;DR from [3]: to have this plugin available, the argument > EXTRA_OBJS="contrib/prometheus-exporter/service-prometheus.o" just has to be added to the `make` line. From a Gentoo package maintainer's point of view, I am not sure if this would require an extra USE="prometheus" wrap within the ebuild, or may just be added unconditionally as AFAIK it does not depend on any other thing but the extra object to be linked.

Has just been added to 2.0.0. Thanks!
