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.

OPTIONS

       -p datafiles_path
           Specify the pathname where are located the daily data files.  Default path is: /var/log/sysstat

       -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:

       last showed graph

       y limits for each kind of graph

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