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

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

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.
