NAME¶

isag - Interactive System Activity Grapher

SYNOPSIS¶

isag [-p datafiles_path] [-c config_file] [-ght gr_height] [-gwd gr_width]

DESCRIPTION¶

The 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.

-c config_file

Specify the configuration file used by the isag command. The contents of this file may depend on isag version number. Default config file is: $HOME/.isag.cfg.

-ght gr_height

Specify the height of the chart area. Default value is: 400.

-gwd gr_width

Specify the width of the chart area. Default value is: 720.

CONFIG FILE¶

As mentioned above there is a config file. There are stored following values:

It seems useful, because new run doesn't need new settings to obtain same scale.
