Support for prometheus

[equilibri0]

Hi there,

it would be great to get the fabio metrics also to a prometheus instance.
Is there any chance for ?

Somehow I knew that this was going to come :) I'm working on another metrics ticket right now and thought the same thing. I'll add it to the list.

Any news on the Prometheus /metrics endpoint ?

This feature would be very helpful to us to measure things like requests throughput, call latencies and status codes, globally and maybe per entrypoint/endpoint as well ? :)

I'd love to see prom support, but in the meantime you should be able to work-around it with statsd in fabio and https://github.com/prometheus/statsd_exporter

I need to wrap my head around on how to configure the naming and to expose the tags. The issue is that some metrics system want a single string as name which flattens all parts of the name into a single value. Others have a base name and other parts as a tag. What makes this a bit more complex is that some of the names are auto-generated and the pattern is configurable. So either this mechanism needs to work for all providers or I need to come up with something else. It probably isn't that difficult but that's the hold-up. Same for #165 .

Any progress on updating the internal Registry api to support labels? It would be a boon to both prometheus support as well as datadog style statsd+labels and others.

IMHO, part of the solution could be as simple as passing into the Registry's update functions a context object which contains the same information that is currently being used to flatten out into a name. And leave it up to the Registry to do the work of either flattening in accordance to the configured template OR using the attributes of the context in whatever other manner makes sense.

work on consul 1.0 has kept me quite busy. I plan to go through open issues soon.
