OneFS or InsightIQ tools for showing CloudPool Tier consumption

We have an Isilon cluster and we will be moving as much frozen data off as we can to one of the cloud vendors (AWS, MS, Google).

Are there any tools built in to OneFS or InsightIQ to show how much has been tiered off to the cloud?

I have found documentation on how to FIND data that has not been accessed so you can get an estimate of what will be moving but nothing on how to get numbers after it is there.

Are we stuck using the cloud vendor tools to tell us how much space we are consuming?   Not a horrible thing mind you, but the powers that be have not chosen the vendor and want to know what kind of info we can get from the Isilon side.

Thanks!
