RHEV incorrectly reports 100% network of RHEV-H

My RHEV hosts all have multiple 10GbE nics, occasionally when they see enough activity to reach 1Gbs or more, then the Rhevm reports that as 100%, with the corresponding alert:

"Used Network resources of host [hostname] [100%] exceeded defined threshold [95%]."

In my case though 1Gbs is actually only 10% of this physical link.

..Can this threshold / calculation be changed somewhere?

Why doesn't RHEV calculate network percentage as an actual percentage of the physical link speed vs the traffic, rather than just measuring up to 1Gbs?
