Skew curve from IBM i

Currently only storage boxes can create a skew curve from their performance data to show how hot the data is I.e 10% of the data is used by 90% of th I/O's.
We would like to achieve the same using IBM i tools (be it performance data, idoctor, PEX, ...)

Use Case:

IBM i admins do not need to deal with storage tools to see data distribution/skew information and could use the already well known tools.

    It's not 100% clear to me what you want to do. However, I think it is likely that either a PEX physical disk I/O trace or DiskWatcher can provide what you are looking for. If you provide some more details I can check.
