Bug ID: 468106 Summary: RAM and CPU usage do not reflect user experience and are not as useful Classification: Applications Product: plasma-systemmonitor Version: 5.27.2 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: ksysguard-b...@kde.org Reporter: ddascalescu+...@gmail.com CC: ahiems...@heimr.nl, plasma-b...@kde.org Target Milestone: --- Created attachment 157809 --> https://bugs.kde.org/attachment.cgi?id=157809&action=edit Screenshot I ran into a state in which my new ThinkPad P1 Gen5's fan remained at max speed for over an hour, even though System Monitor showed a total CPU utilization of under 9% throughout this time. Running htop showed that `nvidia-powerd` was roasting the CPU. "Show: All processes" was checked. Choosing "Show: System Processes", `nvidia-powerd` was shown as taking up only 5% of the CPU. Maybe this is technically correct if only one core was running at 100% and 5% was an average across all core, but this isn't what interests the user. I was using System Monitor to find out what was causing the fan to stay on, and a process at 5% is easy to overlook and not suspect as the culprit. htop's output was more useful. In other instances (may post a screenshot later), the total memory of the running apps from the Applications tab seemed to be under 4GB, yet my 16GB system was thrashing the swap file. Whatever system components were using the other ~12GB, should be shown, ideally with an option to kill them.
