From f959d0809ead017555ef5db60ef081a7fd87ca20 Mon Sep 17 00:00:00 2001 From: Christopher Faulet Date: Thu, 7 Feb 2019 15:38:42 +0100 Subject: [PATCH] CONTRIB: contrib/prometheus-exporter: Add a Prometheus exporter for HAProxy It has been developped as a service applet. Internally, it is called "promex". To build HAProxy with the promex service, you should use the Makefile variable "EXTRA_OBJS". To be used, it must be enabled in the configuration with an "http-request" rule and the corresponding HTTP proxy must enable the HTX support. For instance: frontend test mode http ... option http-use-htx http-request use-service prometheus-exporter if { path /metrics } ...

More and more people use it to +monitor their environment (this is written February 2019). It collects metrics +from monitored targets by scraping metrics HTTP endpoints on these targets. For +HAProxy, The Prometheus team offically supports an exporter written in Go +(https://github.com/prometheus/haproxy_exporter). But it requires an extra +software to deploy and monitor. PROMEX, on its side, is a built-in Prometheus +exporter for HAProxy. It was developed as a service and is directly available in +HAProxy, like the stats applet. + +However, PROMEX is not built by default with HAProxy. It is provided as an extra +component for everyone want to use it. So you need to explicity build HAProxy +with the PROMEX service, using the Makefile variable "EXTRA_OBJS". For instance: + + > make TARGET=linux2628 EXTRA_OBJS="contrib/prometheus-exporter/service-prometheus.o" + +if HAProxy provides the PROMEX service, the following build option will be +reported by the command "haproxy -vv": + + Built with the Prometheus exporter as a service + +To be used, it must be enabled in the configuration with an "http-request" rule +and the corresponding HTTP proxy must enable the HTX support. For instance: + + frontend test + mode http + ... + option http-use-htx + http-request use-service prometheus-exporter if { path /metrics } + ... + + +This service has been developed as a third-party component because it could +become obsolete, depending on how much time Prometheus will remain heavily +used. This is said with no ulterior motive of course. Prometheus is a great +software and I hope all the well for it. But we involve in a environment moving +quickly and a solution may be obvious today could be deprecated the next +year. And because PROMEX is not integrated by default into the HAProxy codebase, +it will need some interest to be actively supported. All contribution of any +kind are welcome. + +You must also be careful if you use with huge configurations. Unlike the stats +applet, all metrics are not grouped by service (proxy, listener or server). With +PROMEX, all lines for a given metric are provided as one single group. So +instead of collecting all metrics for a proxy before moving to the next one, we +must loop on all proxies for each metric. Same for the servers. Thus, it will +spend much more ressources to produce the Prometheus metrics than the CSV export +through the stats page. To give a comparison order, quick benchmarks shown that +a PROMEX dump is 5x slower and 20x more verbose than a CSV export. + +Exported metrics +------------------ + +* Globals metrics +
