Subject: The ports on the switches doesn't seems to display correct network throughput



Hi Team,

I installed Observium recently. It seems to be working just fine.

However, I do see discrepancies in the throughput result.

When I run a network performance tool (Nuttcp) on one of the server and monitor the corresponding port on the switch through observium. I observe that the the server is generating around 9.8 Gbps data. If I check the ports directly on the switch I see same thing (~9.8 Gbps) but when I see in through observium on the corresponding port , I see frequent spikes to 12 - 15 Gbps. I am not sure why I am seeing these high value because the NICs on servers are having a 10 G NICs and I never see anything higher than 10 Gbps on server or on the port on the switch. But the real time graphs on Observium shows the spikes of around 12 - 15 Gbps.


I would be really glad if you help me on this. I really like the tool but the discrepancy in the throughput result is kind of driving me crazy.



Thanks!
