[mrtg] Monitor TenGiga ports

I'm monitoring 3x10G port channels with traffic consistently around
15-20G as well as 4-5G on single 10G's.

 

Are you using the 64bit counters? public at 1.1.1.1:::::2      Something
like that? You need to use that in order to get the 10G 

 

What are you using for your cfgmaker commands?

Hi guys,

It took me sometime, I upgraded to mrtg-2.15.2 and I still get 100%
bandwidth of 4.19 Gbps.

1 more thing, when you say you collect with "no problems", did you
really saw traffic over 4 Gbps?

 

Thanks,

Gil.

Hi,

I am using version 2.11.1. I will try to upgrade and see what happens.

 

Thanks to all for your answers,

Gil.

We are running 10gig switches on our 4 6513's and using mrtg 2.17 have
seen no problems

Which version of MRTG are you running? I had a similar problem but when
I upgraded to the latest MRTG it started discovering them all as 10G
ports and have been monitoring a few hundred of them for a few months
now.

Hello,

I monitor TenGiga ports on Cisco routers (6506/9) with MRTG using 64-bit
counters (:::::2).

As I understand 64-bit counters can fit 10 Giga bit, nevertheless the
max bandwidth shown is ~4Gbps.

Why is that? Or what am I missing?

 

 

Thanks,

Gil.
