Re: [vox-tech] Measure network usage?

[MB]

I like ntop ( www.ntop.org ).  It has a nice SSL server w/interface and 
graphs to view what is going on, and it uses nmap, lsof, and several 
other network utilities to find out about the machines on the network ( 
and the remote connections )

I have a few Linux boxes that have uptimes of days to months.  I need
to try to estimate bandwidth usage for a long-ish period of time (e.g.,
days or weeks) in order to characterize how much bandwidth I use
(to decide on level-of-service issues for a new ISP---I have to move :(
) .   Is there a way to tell the amount (in bytes) of traffic sent and
received by a running box?  Is there a simple *non-intrusive* tool that
might "add a little value" to whatever is built-in?  I'm aware of MRTG,
and Orca, but these are overkill for this type of problem.
     

Take a look at the output of /sbin/ifconfig. It should have a line like
RX bytes:2328595615 (2.1 GiB)  TX bytes:3104087047 (2.8 GiB)
or so. Have a script dump the byte counts to a text file once an hour, and
then you can do a little simple analysis with a hand-rolled tool.
   

That was the first place I checked, but <slapping hand on forehead>
I saw RX/TX packets and missed the byte count.  I just man'd ifconfig,
noticed it used /proc/net/dev, saw byte counts in *there* and started
wondering why they didn't show up with ifconfig...
Now, if I can extract some info from my router, I might have some idea how
much data exits and arrives at my network...
Thanks.
