Error in interface speed for bond's

[James_R3V]

Hey everyone,

Running into an issue that is somewhat stumping me. I use lagg interfaces in debian and occasionally I'm getting odd alerts that completely exceed the interface speed.

For example I have an interface called bond0, its a pair of 25gb interfaces in a LAGG (so technically 50gb). However I'll see throughput of 97.61gpbs on my bits received graph (and thus an alarm) with random spikes which will of course alert me. Where/how is it determining that bond speed? Just doubling the 50gb for some reason?

Any insight or pointers would be helpful as I'd like to see interface throughput.

Thank you!

How are the bond0 items (bits received and speed) configured?

its automatically detected at the moment, however can you possibly point me in the correct direction? I'm using the zabbix agent but from what I can see its basing it on the Network Interface Discovery component.

net.if.in["bond0"]

net.if.in is a Zabbix agent item, so it gets the data from the Linux OS. You can compare the data obtained with for example these instructions: https://docs.kernel.org/networking/statistics.html

Run the ip command for the bond0 interface with the same interval as your Zabbix items are configured. Then calculate the amount of transferred bits per second from the counter values you see, and compare it with what Zabbix shows you.
