FlowScan users,

I received this message to my personal mailbox.  I'm following-up to
the list and will bounce this reply to the sender so that he can
follow-up in the list if necessary.

None of my scripts (nor FlowScan) read arts++ files.  FlowScan uses
flow collectors (or "flow sources" if you like) such as cflowd or
flow-tools only as a source of raw flow records.  FlowScan reads those
flow records and analyzes the flows there-in, subsequently storing
summary data in RRD files, like MRTG or Cricket.

When used with cflowd, FlowScan reads timestamped raw flow files, such
as are produced by cflowd after patching it and using the "-s" option,
which I added.

All this is fairly thoroughly described in the INSTALL documentation:

and in my paper on FlowScan, linked from here:
