[mrtg] Monitor TenGiga ports

[Geba, Scott]

I had this issue a while ago and I upgraded MRTG and it worked and now
works great. I am unsure of your issue, do you set maxbytes as a default
in your template anywhere? I use the standard cfgmaker interface
template. I am monitoring hundreds of 10G and 10/20/30G port channels
without an issue for quite some time. I would check your interface
template to start with, see where you can go from there.

I don't think any of that really matters. It's the MAXBYTES value that
shows what 100% bandwidth is.
For instance, my 10 Gb ports show the following after I run cfgmaker:
MaxBytes[10.48.58.1_TenGigabitEthernet2_2]: 536870911

This translates (in my routers2.cgi frontend with RRD backend) to '100%
Bandwidth (4.29G bps)'.
However, we know that's not right. So, I change it in the config to the
following:
MaxBytes[10.48.58.1_TenGigabitEthernet2_2]: 1250000000
...and now I see '100% Bandwidth (10Gbps)

Incidentally, I also had to change my 20 Gb port channel to:
MaxBytes[10.48.58.1_Port-channel1]: 2500000000

Why is MaxBytes not calculated correctly from the beginning? I'm not
sure. Could be a cfgmaker issue or it could be a problem with my
interface template. I don't yet have enough TenGigabitEthernet
interfaces to worry about it. I can change them all by hand for now.

Thanks,
Garry

Yes I am using the 64bit counters. Example
password at Some_Device_Name:::::2.

How you store the data? As MRTG gif or as .rrd file? What front-end are
you using?
