Implementing KSysGuard sensors simple example.

Prequesities: KDE, Perl, nc

Imagine you have a program that monitors some value important for you. You want the value to be plotted or displayed in the KDE systray.

The most _____ way is to add it to KSysGuard as a sensor.

Step 1. Create, for example, "/home/vi/code/sensor/sensor.pl" with the following content: #!/usr/bin/perl -w $|=1;

print "ksysguardd 1.2.0\n"; print "ksysguardd> ";

while(<>){

   if(/monitors/){

print "random\tinteger\n";

   }
   if(/random/){

if(/\?/){ print "Random Value\t0\t100\n"; }else{ print int(rand()*100),"\n"; }

   }
   print "ksysguardd> ";

}

Step 2: Launch KSysGuard, File->Connect Host->Custom Command, enter "/home/vi/code/sensor/sensor.pl" in the Command field, OK.

Step 3: Open "127.0.0.1", find "random Integer Value", drag it to some sheet.

You will see your sensor (random value from 0 to 100 in this case).
