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).
If you want to see the plot is your systray, follow this:
Step 1: Add "KSysGuard applet to the desktop".
Step 2: In there's no spare displays, choose "Configure System Guard" in the context menu of the applet and increase "Number of displays".
Step 3: Launch KSysGuard, follow previous example to get access to your sensor.
Step 4: Drag and drop from "random Integer Value" to the free display in the systray.
Step 5: "Signal plotter", then you will be asked again to provide the data source. Choose "Custom Command" with the same script.
[Step 6: Open properties and remove grids and lines to clean up the plot]
