Network Interface Alert - Not understandable value

I get the following alert title:

[zenoss] 10.0.0.5 threshold of high utilization exceeded: current value 1616785.482533

with contents:

Device: 10.0.0.5
Component: vnet0
Severity: 3
Time: 2015/09/30 09:04:33.000
Message:
threshold of high utilization exceeded: current value 1616785.482533

Can I somehow change it to get a more understandable alert

I have seen a few articles (e.g. http://community.zenoss.org/docs/DOC-2557 , http://community.zenoss.org/docs/DOC-2554#Interface_High_Utilization_eve... , http://community.zenoss.org/docs/DOC-13003 )
regarding transformations but are rather old and I was wondering if there is a more recent one....

If not could you please be of assistance regarding transformations....How to change, where etc.

All the best,
