When you ask "I would just get the value for my VM", what do you mean exactly?

It doesn't make sense that you would want the VM name to label each of these datastores in the legent, as it would be the same VM name for each datastore associated with this VM.

I have this data with the Community Datastore : http://en.community.dell.com/techcenter/virtualization/infrastructure/w/fog-virt-wiki/5799.community-cartridge-vmware-datastores

In the time plot i just want data for my vm not for all datastores vm.

I would like to create a read/write latency for my selected VM and not all vm on the same datastore.

The issue is that you have not arrived at the correct path to the data you need, because you are looking at one item of a list of datastoreUsages for each VM.

On the drag and drop selection, you are seeing only 1 item on the list, so it looks like a straight path to the data.

You could add an Additional Context to your chart:

vmDatastoreUsage     =     context VM  path storage/datastoreUsage           return first value

You would then chart the vmDatastoreUsage  path datastore/readLatency    (or datastore/writeLatency, or datastore/totalLatency)

OK. Each VM references a list of VMWare Datastores. Each VMWare Datastore references a list of VMWare Datastore Usages.

Have you seen any evidence that read/write latency is available for each VM?

I tried your solution but it's not functionning,

i've got this when i'm doing what you said.

I don't get value,

and when  i'm looking my old time plot, i have this :

I choose the brown vm on the first screen but it shown 0 latency.

Thank you for your help
