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.
Release Notes: This release adds a Spanish template, and a contrib directory, containing some script and configuration files.
Release Notes: A string bound check bug in ifgraph.pl readconf() was fixed. makegraph.pl was not verifying the type when it was a command target. A bug in the [no]legend and [no]rigid options with OID and COMMAND targets was fixed. The update and precision directives were added. The [no]minorgrid option was added, and causes the --no-minor option to be passed to rrdtool. The -T flag was added, which will make ifgraph.pl use the $^T Perl variable in the rrdtool updates. The default is to use the rrdtool "N" string.
Release Notes: This release fixes some bugs and added some observations in the documentation.
Release Notes: A new graph=[yes|true|no|false] directive was added. The global variables rrdtool, rrddir, graphdir and template now have default values. Color::Rgb was added to the script so it can convert RGB strings to the hexadecimal required by rrdtool. Fixes were made for ifgraph not checking the heartbeat of the rrdfiles or not checking if a COUNTER rrd was getting reset. ifgraph can now execute commands and get its output to feed an rrd database.
Release Notes: This version is basically the same as 0.4.9rc2 with support for MAC addresses in the HH:HH:HH:HH:HH:HH format octet string returned by some SNMP agents. This was added only in the find-if.pl script, not in ifgraph.pl and makegraph.pl.
