Is there anyway to increase the length of time DFM holds capacity usage data? currently it only keeps 12 months worth of capacity usage data, which isn't ideal when doing long term capacity planning.
The History is kept even beyond 1year. In fact the data in the year history table is unlimted. From UI you would be able to access only upto 12months worth of data. To get data beyond 1yr, if it exist use the dfm graph cli. Below is a link to document on DFM and capacity management.
