Possible to alert on an interface that rises x% in a given time?

All,

I'm curious if it's possible to create an alert for an interface that rises either some % or to a certain Mbps over a given time period, is that possible?

 

We have thresholds setup to alert us if any interface goes above 80%, but I'd like to assign specific interface alerts that I can adjust..

 

I'm thinking I could do something with a poller, and a transform, maybe...

 

Thoughts?

 

Thanks!
