Hi,
This patch adds a new component in contrib. It is a Prometheus
exporter for HAProxy.
[snipp]
More details in the README.
I'm not especially a Prometheus expert. And I must admit I never use
it. So if anyone have comments or suggestions, he is welcome.
Just for my curiosity, what's wrong with the haproxy_exporter especially
that haproxy_exporter uses the csv format from haproxy ?
Hi Aleks,
Nothing wrong. haproxy_exporter works pretty well AFAIK. It is just an
external component and it may seem a bit annoying to deploying it
instead of having such functionality built-in in HAProxy. Furthermore,
haproxy_exporter "only" exports proxies and servers statistics. Unlike
the built-in exporter, haproxy_exporter is limited to what the stats
applet exposes in HTTP. So, it cannot export global information. And
with a bit more work, we can imagine to export even more info from the
built-in exporter.
However, to mitigate what I said, it is not an aim for HAProxy to
support all monitoring and alerting tools (Prometheus, Graphite,
InfluxDB, OpenTSDB...). So it was added under contrib and not officially
integrated into HAPRoxy. It is a first step of a reflection on the
output format for stats to let all kind of external tools to retrieve
them. But it not a priority either. It was just a quick development and
now we will wait and see if there is a particular demand to go further
and how we could address it, if any.
