| ifGraph is a set of Perl scripts created to help network administrators
to
visualize network flow on a daily, weekly, monthly, and yearly basis. The
graphics are created with RRDTool, and it shows bytes (in/out) and errors
for
each interface. It also shows the current/average/max use and the
respective
link/interface usage in percentages. The program also outputs HTML files
to
make the visualization of the PNG images more friendly and easy. |
