[mrtg] Router appears to drop out, but provider sayes its ok

[Nick Earle]

I'm using MRTG to monitor around 150 routers.

On a couple of the bigger routers (CIR=4Mb) I'm getting 'dropouts' every 4 hours. The period between dropouts is proportional to the amount of traffic, so if there is more traffic the dropouts appear more frequently. Our network service provider is assuring me that there dropouts are not real!

I was wondering if this might be caused by counter overflow?

Does anyone now if there is a setting I can use to handle counter overflows more elegantly?

Regards,

Nick Earle
