ksysguard is no longer maintained, in Plasma 6 there is the Plasma system monitor for this task. If your issue still happens with the Plasma 6 replacement, please re-open and we can move this bug to the new product, thanks! |
Created attachment 151588 [details] screenshot SUMMARY On some rare occasions gsysguard receives some very high value for CPU utilization for one of the CPU cores. That value exceeds what it can be in real life. If user has a plot, where he prints together all the CPUs utilization together, this sudden spike makes the plot to dynamically change its scale, which in turn makes further readings from the plot impossible, until the spike goes away into history and plot scale returns back to normal on its own. See screenshot please - the insane high value came from gsysguardd was 3e+19% IMHO, for the sensors/metrics we know the physical limit (like this one - total load for CPU cannot physically exceed 100%) there should be some simple protection in place, like to report the MAX value when the sensor' readings ksysguardd gets is unreliable. Freezing the scale on front end side is the workaround off course, but you discover this option only after this bug plays a trick on you :) SOFTWARE/OS VERSIONS System monitor version 5.20.5 KDE Frameworks 5.78.0 Qt 5.15.2 (built against 5.15.2) The xcb windowing system ksysguard 4:5.20.5-2 arm64 ksysguardd 4:5.20.5-2 arm64 CPU is ARM RockChip RK3399 Linux kernel 5.18.5-rk3399
