[Observium] No graph policy description on Cisco CBQoS graph

Dear All,

I wonder why Cisco CBQoS graph on Observium Pro have no graph description(policy name) show up? Since I observe there is policy description name showing up on Observium Community Edition.

It should display something like:

CUST-Name / class-default (input) CUST-Name / class-default (output)

Can you guide if we can enable it on the script somewhere?

Thanks so much.
