[mrtg] Problem with data gathering when computer sleeps

[Eivind Samseth]

I'm having a problem getting correct data about the traffic  
throughput whenever my Mac has been asleep, and mrtg collects data  
again. If I uploaded with 200 kbps on the last reading before it went  
to sleep, the period it has been asleep will not have the throughput  
set to 0, but 200 kbps. This way I get inflated values, as I'm using  
mrtg to monitor how many GB I've transferred in the last 24 hours.

Have anyone experienced something similar, and is there a way to fix  
this?

I'm running mrtg-2.15.2 together with NET-SNMP version:  5.2.1  
locally on my Mac
