Subject [jira] [Commented] (YARN-6492) Generate queue metrics for each partition
Date Thu, 03 Aug 2017 18:13:00 GMT

Sunil G commented on YARN-6492:
-------------------------------

Thanks for working on this patch.

Few thoughts
{code}
	PartitionMetric (labelX)
		QueueMetric (A)
			metrics
			Usermetrics 
                         QueueMetric (A1)
			     metrics
			     Usermetrics
                          QueueMetric (A2)
			     metrics
			     Usermetrics
                 QueueMetric (B)
			metrics
			Usermetrics
	PartitionMetric (labelY)
		QueueMetric (A)
                          QueueMetric (A1)
                          QueueMetric (A2)
                 QueueMetric (B)
			…
         Partitions			
         QueueMetric  //existing for default metrics to maintain compatability
			metrics
			Usermetrics
{code}

I was trying to unroll and was trying to gave the same similar to Naga's comment and also
as per UI. Is the way we are planning this patch?

This means that we need to overhaul a bit of existing metrics layout. I think its better we
finalize the hiearchy and then we can jump into poc and etc. Thoughts

> We are interested in having queue metrics for all partitions. Right now each queue has
one QueueMetrics object which captures metrics either in default partition or across all partitions.
(After YARN-6467 it will be in default partition)
> But having the partition metrics would be very useful.
