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/GIF/GD images more friendly and easy.
