----------------------------------------

This ticket combines too many things:

Used / allocated naming is very inconsistent now. Sometimes allocated means allocated, sometimes "total available": http://imgur.com/zLEX5pU

This was a bug, fixed here: https://github.com/apache/mesos/commit/65ecc0a7c87880f382c13062d4d21c0cd178c945

I propose to have the following:
used / allocated for each framework and task
user / allocated / total for each slave and for cluster as a whole
Master now shows idle and offered, slaves have "slack" capacity too that might be used for preemptive tasks. Not sure if it should be visualized as well.
It looks like fetching cluster-wide utilization requires fetching stats from each slave, so it can be added separately later.

What I'm distilling from this is a request for showing utilization from the master pages, since we already display it per agent. We haven't done this since, as you said, the master does not have utilization information of the whole cluster at the current time. It's possible we could build something for this. I'll close this out, can you file a ticket with the specific request for displaying utilization from the cluster-wide pages?
