Impossible high traffic value on traffic-billing

It seem to bee observium are not able to detect counter-wraps. (I think so)

We have much Ports with impossible traffic-values on our billing (see attached screenshot with the 30GBit Peak on a 1GBit Interface).

This bug is a blocker for billing!

Maybe observium need a OutOfRange-Feature like in RTG.
Our RTG Billing ist absolutly correct.

Here are a explanation for the OutOfRange Feature in RTG:
The OutOfRange (OOR) setting in rtg.conf is just a sanity check to keep
bogus data from entering the database. For example, rtg is polling a
64bit OID on a router; the last value returned was 100. The router is
rebooted before the next poll. On the next poll, the router returns 50
for this OID. RTG must assume this was a counter wrap, so the delta value
is: 2^64 - 100 + 50, corresponding to approximately 4^17 bps which is
clearly impossible. This is where the OOR comes into play. It is simply
a sanity check that is set to a reasonable value. 93750000000 * 8 / 300 ~=
2.5Gbps, so most people will not want or need to adjust the OOR setting.
