---------------------------------
Sorry, [~codecraig] I misunderstanding your problem at first. I think you mean
the slaves page not the home page at first.
If you mean home page. Let me explain my understanding here. {{Used}} equals to
those resources used by executors now. {{Offered}} equals to those resources
have already allocated to frameworks but not yet used by executors. {{Idle}}
equals to those resources not yet allocated.
If you mean slave page. {{Used}} equals to those resources that used by this
slave executors. {{Allocated}} equals to those all resources belong to this
slave.
> Resources clarification in Mesos UI
> -----------------------------------

> Key: MESOS-4586
> URL: https://issues.apache.org/jira/browse/MESOS-4586
> Project: Mesos
> Issue Type: Improvement
> Affects Versions: 0.26.0, 0.27.0
> Reporter: Craig W
>
> On the Mesos UI under the "resources" section when it lists CPUs and Mem,
> it seems to be calculated by sum up every executor cpu and memory statistics,
> which would be less than <= "allocated" resources.
> On the page that displays information for a slave it shows the CPUs and Mem
> show used and allocated.
> When I look at the Mesos UI front page, I was looking at "Idle" resources as
> the amount of resources I have available for offers. However, that's not the
> case. It would be nice to have it show the amount of "free" or "available"
> resources as well as "idle", so I can better determine how many resources I
> actually have available for scheduling additional tasks.
