AutoFocus Short Description
AutoFocus is a traffic analysis and visualization tool that describes
the traffic mix of a link through textual reports and time series
plots.
The traffic reports are computed automatically. They describe the
traffic mix by giving the traffic of selected traffic clusters
(aggregates) defined using the source and destination IP address,
source and destination ports and protocol field. There are separate
reports that measure the traffic in bytes, packets and flows.
Using traffic clusters, one can divide the traffic into meaningful
categories. AutoFocus uses RRDtool
to produce time series plots of the traffic mix with each category in
a different color.
AutoFocus produces reports and plots for various time periods ranging
from weeks to half hour intervals. Also, the user can drill down into
separate pages for each category. The filter from the user interface
allows drill down into arbitrary directions.
AutoFocus accepts two types of input: packet header traces and NetFlow
data. Both types of input can be sampled, but AutoFocus only
compensates for the sampling in the reports that measure the traffic
in bytes and packets, and not in those measuring the traffic in flows
(to avoid giving biased estimates).
