LLD Graph disk stats

[zabbn00b]

Hey,

I've created an LLD which is working ok to grab the disks e.g.

disk1
disk2
disk3

Each disk has stats like serve / wait etc.

I would like to LLD a graph which is

Disk Average Wait

This would like the Average Wait for disk1, disk2 and disk3.

I think this is not possible with the current LLD, can anyone confirm?

Does anybody have a workaround.

Thank you.
