DCFM 10.4.5 increase 5 / 30 Minute historical data collection?

When viewing the Historical Performance Graph screen in DCFM 10.4.5 with a 5 minute granularity with the 'last 1 week' length selected only shows 1 days worth of data. Bumping granularity up to 30 mins and selecting  'last 1 week' only shows around 3 days worth of data.

In order to see a weeks worth of data, the granularity needs to be set to 2 hours which doesn't really capture i/o peaks very well.

I cannot find any information in the DCFM manual allowing you to change the retention of the data being collected.

Does anyone know if this can be changed?

Is there any undocumented tweaks we can make to the config files in DCFM?

However Brocade Network Advisor lets you define the performance data aging interval and allows you to choose between the following 2 options .

Select one of the following options:

• Option 1—2 years data with the following samples

 Raw samples for the last 1 day

 30 minutes granularity for last 3 days (144 samples)

 2 hours granularity for last 30 days (360 samples)

 1 day granularity for last 2 years (730 samples)

Option 2—2 years data with the following samples

 Raw samples for the last 8 days

 1 day granularity for last 2 years (730 samples)

If you change from Option 2 to Option 1, you will lose existing performance data for the

5 minutes granularity for last 8 days (2304 samples) interval.
