SYNOPSISisag [-p datafiles_path] [-c config_file] [-ght gr_height] [-gwd gr_width]
DESCRIPTIONThe isag command graphically displays the system activity data stored in a binary data file by a previous sar run. The isag command invokes sar to extract the data to be plotted.
The data are processed using sar command and slightly transformed to tabular format, and then this format is visualized using gnuplot program.
