Question How to determine peak traffic throughput

[Mike99]

Hi there,

I am trying to figure out, what was my peak network throughput last month.

In latest Plesk, I opened Advanced Monitoring, Network, I selected date range 1-30 April and this is what I get.



Someone with network background, please enlighten me on how to calculate packets/sec to Mbps? I am looking into TX - transmit out, I don't care about RX.

How big is the packet size anyway? Does it matter? How do I figure out?

My peak interface-eth0:if_packets:tx is 3992 packets/sec? What does it mean in Mbps?

Is there any other tool, where I can read peak/maximum values? A tool called vnstat gives me only averages.

Most common packet size is 1,500 bytes. Can go up to 9K.
3992 packets per second * 1,500 bytes per packet * (1 Mb / 1,000,000 bytes) = 6 Mbps
... I think
