Title: Working CPU monitor
Post by: rgrep on October 17, 2004, 02:19:28 am

Hi guys,

I've modified mb-applet-system-monitor so that it no longer always shows 100% CPU usage.  In the below screenshot the applet on the right is the original version and my modified version is on the left:



Cheers,

Matt

Hope someone finds this useful.

Great, that needed bashing. Now it really works and is something I was missing, thanks.

Btw, when I raise the CPU load to 100% instanteneously ("while true; do true; done" in bash, for instance), the indicator display doesn't show the change in one step when it updates -- rather, it shows CPU gradually increasing step-by-step until it is full. When I remove the load, it goes down the same way. Was that a feature or maybe some problem?

That must just be due to the way the applet works.  I just installed it on my desktop PC and it had the same behaviour.  The code says it's based on wmbubblemon which I also run on my desktop, and while wmbubblemon also increments/decrements the CPU usage it does so much faster than mb-applet-system-monitor.  If anyone wants to report this as a bug make sure to send it to the matchbox project rather than pdaXrom.

I forgot to mention how the modification works.

Basically all I did was make the applet ignore kapm-idled in the CPU usage statistics.  The way this works is by subtracting kapm-idled's user/system CPU time from the current total user/system CPU time.  The PID of kapm-idled is discovered by the applet when it first starts by executing "pidof kapm-idled".

I guess it is just because wmbubblemon does the same number of graduate steps, but refreshes more often, each refresh taking one step. Clearly a once-nifty graphical effect of wmbubblemon turned into an outright bug in mb-applet-system-monitor
