Draw graph for Linux sar output using ksar

I’ve recently heard about this tool , as it is said we are learning things until the death (:

Our company is saving sar output in a text file periodicly and after performance or other issues we need to analyze it’s output to find out which resource was busy and when.. analyzing text file is time-consuming and can also cause eye tension.

Output in sar:

00:00:01        CPU      %usr     %nice      %sys   %iowait    %steal      %irq     %soft    %guest    %gnice     %idle

CPU, Network, Disk I/O, etc. activities are logged.

Same text file analyzed by ksar tool and graphycally displayed is the following:

Full list of items that can be seen graphycally are the following:

Now I will show all necessary information that is necessary to use this tool:
