closedBuild HAProxy Package with buildin Prometheus exporter
100%
Description
Now if you try use in fronend:
http-request use-service prometheus-exporter if { path /metrics }
stats enable
stats uri /stats
stats refresh 10s
you will get error: error detected in frontend 'http-stats' while parsing 'http-request use-service' rule : 'prometheus-exporter' unknown service name.
Prometheus exporter is must have. For example Telegraf HAProxy exporter not give even half of info that Prometheus provide. Official post https://www.haproxy.com/blog/haproxy-exposes-a-prometheus-metrics-endpoint/ with explanation and build instructions.

Hi @Viktor can I test it on my pfsense 2.4.5? And if yes - then how? I have System Patcher but doesn't know if it can change build stage. Thank you for help.

Just stop using old version, 2.2.22 is old. I don't know why pfsense devs choose to use develop for fresh LTS versions and non-develop naming for the seriously old LTS versions. It's confusing and I don't support this naming, instead they better name packages as haproxy-22, haproxy-24, haproxy-26 and for version of the package use UI build version, e.g.: haproxy-24 v1.0.5 as it done for Zabbix package already.
About USE_PROMEX, it's in place so this ticket should not be reopened:

P.s. minor version of both packages is really old - was updated last time at the end of 2021! HAproxy 2.2 version is already 2.2.29 and 2.4 is 2.4.22, both of them has fixed critical bug and in general even without critical bugs it's not okay to not maintain up to date version for so long. I not speaking about the critically old OpenSSL version which is part of it (1.1.1l) which has bunch of known CVEs: https://www.openssl.org/news/openssl-1.1.1-notes.html
