... for measuring traffic in MB/s i can recommend ifstat:

[ORIGINAL POST]
I am busy trying to troubleshoot my network (Unix VLAN). This should be
a very simple task, monitoring the traffic between 2 servers, but I
cannot find the right tools to do this.
I have tried snoop, ntop, iperf (of which I could not get to install the
latter 2 - I had lots of installation errors, following the install
procedures, and with my limited Unix knowledge, I could not get this to
work). I am still searching on Google, but I would like to tap into the
knowledge here - you guys (&girls) have lots of experience in this.
Surely there must be an easy way to look at the traffic between 2
servers - for example how much data is transferred between the 2 servers
(M/sec), etc.
My network admin tells me there is nothing wrong with his network, and I
tend to differ, but I need to prove this and give him facts.
