@anmolnar thank you for following up on this.
Background of this issue is on JIRA
https://issues.apache.org/jira/browse/ZOOKEEPER-3092
the plan is the following:
- send this patch and discuss the API for a MetricsProvider
- send a second patch for the boostrap of the MetricsProvider + NOOP
implementation + minimal instrumentation (as an example)
- send the patch with full instrumentation of all the current metrics
exposed in 4LW
- start the same work on the client
Examples are:
- Prometheus
- Dropwizard
- BookKeeper Stats Loggers API
- Hadoop Metrics
I can send the second patch if it is worth but I would like to discussion
to be as narrow as possible, a, huge patch won't be reviewable.
At the moment this is the high level API, we will instrument all the code
with probes, starting from all of the current instrumented points.
I think sharing a Google Doc won't help so much, it is better to share code
in this particular case
