Rightsizing Lookback period too short

Pertaining to and referencing Case number TS022323749.

Regarding having only a 10 or 30 day lookback period in rightsizing is too short of a period to get a good picture of system utilization, you must lookback 60-90 days of utilization history in order to see the full picture of utilization for accurate rightsizing. Can you add a deeper lookback period.

Hi Gary, In Rightsizing, the look-back period is only set to 10 and 30 days by design. An increase to 60 - 90 days would be considered a product enhancement that would need to be filed at ideas.ibm.com/new-idea including your business use case and desired result.
