hardware-monitor cpu monitoring should not include iowait

Bug Description

Binary package hint: hardware-monitor

After booting my machine, updatedb is usually started by anacron and the hardware-monitor shows 100% cpu load for some time. Inexperienced users who don't know what updatedb is may be surprised and concerned why their CPUs stay at 100% load minutes after booting has completed.

Therefore, my suggestion is that hardware-monitor should also substract iowait from the total cpu load because of iowait not being actual cpu load. The cpu can yield cycles to other processes while waiting for the IO to complete.

The cpu-monitor in the hardware-monitor applet currently computes the cpu load by substracting "nice" and "idle" loads from "total" cpu load reported by libgtop.

Make hardware-monitor ignore iowait times Edit (2.1 KiB, text/plain)

Here is a patch that changes the behaviour as described above. I've also sent the patch to the author (he didn't answer yet)

The author of hardware-monitor told me that he has commited the patch to his sources, fixing the issue for the next release.

Therefore, this bug can be closed now (with either adding this patch to the ubuntu package already, or waiting for the next hardware-monitor to come).
