Version: (using KDE Devel) Installed from: Compiled sources This article -- http://www.linux.com/article.pl?sid=04/05/17/1832239 -- makes a good point: it would be nice if KSysGuard had a way of notifying the user when certain threshold values are exceeded for each sensor. Ksysguardd already provides min/max values for a sensor. Perhaps those could be used as defaults?
ksysguard is no longer maintained, in Plasma 6 there is the Plasma system monitor for this task. If your wish is still valid for the Plasma 6 replacement, please re-open and we can move this bug to the new product, thanks!
