Hi fellows, I would like to start the 'real work' about Metrics providers. I am seeing new patches coming from FB friends and this is great.
We have three topics here: - implementing providers (Prometheus will be the first) - packaging: I would like to separate MetricsProvider API from zookeeper server into a separate Maven module as soon as we drop Ant - instrumentation ! Instrumentation is the hard part and we have to coordinate the work. IMHO a good goal would be to have all pf the existing metrics ported to the MetricsProvider API, with a Provider implementation which exposes metrics in the legacy way. Facebook friends already did a great work in introducing a common way of defining metrics, we only have to refactor a bit this system in order to move to the new API. The point is.....how can we coordinate? Is it too early to start? Given that most of the new metrics have been designed and are running in production at Facebook I think that such work should be driven by one of our 'Facebook friends', anyway I am available to do whatever is best in order to move this work forward.
