Bonded/teamed interfaces not graphed correctly for lin & win

[maxw]

Hi,
I have a problem where bonded (Linux) or teamed (windows) interfaces are not graphed correctly. They do not show the full utilisation of the interface, only a fraction. I've seen this reported here too but no answer. I will show an example for Linux and Windows.....

Cacti shows:

Has anyone else had and fixed this issue? If you need any output from snmpwalk etc let me know!

And here is what it looks like in the "create graph" screen....

I'm facing the same problem. Did your fine a solution to this?

Nope
I don't understand why more people haven't hit this problem as most production environments use interface bonding/trunking/teaming!
I'm using cacti 0.8.7g, Net-SNMP 5.3.2.2, PHP 5.3.3 and spine on RHEL 5.5 x86_64.

I know this is an old thread but I ran across it while looking into the same issue. What I have found is the problem lies with how SNMP reports link speed for bonded interfaces on Linux. The Linux bonding driver does not report speed so SNMP defaults to an incorrect speed. In my case 2 bonded 1G interfaces (bond0) reports a link speed of 100M and the graphs break once the traffic goes over 100M speed. Here is a RedHat bug with more detail: https://bugzilla.redhat.com/show_bug.cgi?id=704575

Yea, you definitely have to modify the max values in the RRDfiles, and you also have to make sure you are using 64bit counters, which might require Net-SNMP's agent on Windows since Microsoft does not support 64bit counters on either their 32bit or 64bit OS'.

edit your snmpd.conf and add

interface bond0 6 1000000000
interface bond1 6 1000000000

works on linux
