Datastore Total Capacity and Used space

Hi,

I have :

Created a group with all of my datastores in it

Created a supermetric of

sum(Datastore:Capacity|Total Capacity)

sum(Datastore:Capacity|Used Space)

Then assigned them to the group object via policy so they are collecting metrics. Yay.

When I edit the supermetric and press the visualise super metric button the metric gathers and displays data back as far as seven months (for both super metrics)

When I add the supermetrics into a view and do a report on them it only shows about a day worth of data (when I created the supermetrics).

Is there any way I can show the data going back 7 months in a report ?

Thanks
