dbinspect query help

I'm trying to write a dbinspect query to calculate the # of days of data that is stored in our hot/warm storage partition and our cold storage partition, for each index. So for example trying to get results like this:

Index, Hot/Warm Days, Cold Days
_internal, 10, 80
os, 12, 78
etc.

OR

Index, Hot/Warm Earliest Time, Cold Earliest Time
_internal, %Y %m %d, %H:%M:%S, %Y %m %d, %H:%M:%S
os, %Y %m %d, %H:%M:%S, %Y %m %d, %H:%M:%S
etc.

Can anyone help me figure out how to do this with dbinspect?

thanks,
Marcel

This query is going to be super slow going about it from a DB inspect way.
Make sure to set the time for this greater than your cold storage typical data age.
It's a 3 step join to make the table look nice. This would be something to put as a report.
