Off hand, nothing obvious.  However, the raw data you want is in the RRDs,
if you enable the plugin.  The default is 300s resolution, but you could
push that to say 15s without too much trouble unless it's a huge network.

Once the data is in the rrd, you would have to extract it and graph it using
something external.

For example, there are RRDs like these:

/usr/share/ntop/rrd/interfaces/eth2/hosts/64/154/81/15/bytesSent.rrd
/usr/share/ntop/rrd/interfaces/eth2/hosts/64/154/81/15/bytesRcvd.rrd

one per host.

Export from RRDs is easy - see man rrdxport for how to "Export data in XML
format based on data from one or several RRD"

Then you would have to combine them - pretty simple in perl or awk or
python - and produce the graph you want.

Subject: [Ntop] Bandwith Measurement per User (IP)


Hi,

I am totally new to ntop but already really impressed of it.

Is it possible to generate a graph which shows the bandwith - seperated
by
user (IP) - of a special subnet? I am thinking of going to a mirror port
of a
switch and log graphs for every User (seperated by IP). I found a tool
named flavio
at sourceforge but am not sure if this fits my needs.

What I want to have in the end: A graph per IP which tells me the used
bandwith (plotted
over the time). The graph must be detailed, like every second or two.

What tool can I use ?

Thanks for your help.



Markus
