System Load Viewer

Last year I've blogged about the missing system monitor with the three bars for the panel and about its port to Plasma. Meanwhile other developers also did a port called System Status. In a collaboration with them we finally have the applet back in KDE's subversion, the name is now "System Load Viewer" and it uses the data engine "systemmonitor" that already exists in KDE 4.2.
So if you want to have the plasmoid for your KDE4.2 desktop, it should be straightforward to compile/install.
On the screenshot you can see the plasmoid in action. There are two instances, one on the panel and one on the desktop. The one on the left is the KDE3 one.

It's worth to mention that the plasmoid already supports more featues than the KDE3 version. Features include:

• show all cpus (for computers with multicores)
• tooltip updates continuously
• nicer visualization (maybe needs some more tweaks)
  

As soon as the KDE 4.2 freeze is over we'll have to see where we can put the plasmoid to make sure it's available for KDE 4.3 :)

"I miss the applet which shows system usage"

...is one of the comments on Sune's blog. "I won’t call it a a must-have, but I’d love to have it back :D". Well, I call it a must have, that's why I've ported it to KDE4 a week ago:The code is not in svn yet (here is the code for now). I still had issues with correct resizing and believe there was also a bug in the plasma lib when I developed it which seems to be fixed now. I didn't have time for more testing, but finally this has to go in for KDE 4.2 :)
Besides that, I'm not yet content with how the data engine publishs data. The situation is that all system monitor data is extracted in one tick, but I still would like to publish it in three categories: cpu, mem and swap. But if I do so, an applet's dataUpdated() function is called 3 times and that's not what I want. So for now I put the data into the category systemmonitor and named the items cpu-total, cpu-kernel, ..., swap-total, swap-used, mem-total, mem-kernel, mem-cached, ... However the other way of categorization would be better :) Any ideas?
