Eric Badger commented on YARN-4236:

Hi, [~lichangleo]. The current patch has gone stale. Are you interested in rebasing it to
trunk? If not, I can do the rebase

> We currently track allocated memory and allocated vcores per queue but we don't have
a good rate metric on how fast we're allocating these things. In other words, a straight line
in allocatedmb could equally be one extreme of no new containers are being allocated or allocating
a bunch of containers where we free exactly what we allocate each time. Adding a resources
allocated per second per queue would give us a better insight into the rate of resource churn
on a queue. Based on this aggregated resource allocation per queue we can easily have some
tools to measure the rate of resource allocation per queue.
