Elliott Clark updated HBASE-6323:
---------------------------------
Attachment: HBASE-6323-0.patch
First try at it. I'm not 100% sure that I am using the metrics2 stuff
correctly. I'm going to spin up a couple clusters to test, but I wanted
jenkins to take a crack at it.
> [replication] most of the source metrics are wrong when there's multiple

> Most of the metrics in replication were written with 1 slave in mind but with
> multiple slaves the issue really shows. Most of the metrics are set directly:
> {code}
> public void enqueueLog(Path log) {
> this.queue.put(log);
> this.metrics.sizeOfLogQueue.set(queue.size());
> }
> {code}
> So {{sizeOfLogQueue}} is always showing the size of the queue that updated
> the metric last.
> I'm not sure what's the right way to fix this since we can't have dynamic
> metrics. Merging them would work here but it wouldn't work so well with
> {{ageOfLastShippedOp}} since the age can be different and it definitely
> cannot be summed.
> Assigning to Elliott since he seems to dig metrics these days.
