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

[Bates, Curtis]

It probably is a counter overflow.  Check to see if the counter you are
using is 32 bit.
You might also want to look at the mrtg release notes because I think a
recent version of MART fixed this problem.

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


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
