How to create a badge in vCops : Write Latency on VM's / Aggregate

Hi all,

Thanks for your communities and for your helpen.

I have a question concerning the vCops. We have a latency problems on some datastore.

The datastores are composed of differents Aggregates.

We have 1200 vm's and 16 Datastores. The version of vSphere is 5.1 and on vCops : 5.7.0

I will create a specific dashboard (i seek a good widget for top-analysis for example) : 

i wish find the (Top30) VM's per Aggregate last 6 Hours with metrics : High latency write en read.

We work with NetApp for the storage en i have instal the Netapp adapter on vCops.

But with differents badge i have no metrics choice for select Virtual machines / Aggr or NAS.

Could you me helpen ?

Greetz,
