The System Load Viewer Plasmoid reports for memory only the used memory including buff/cache; an indication of the really used memory is missing. Therefore, most of the time memory looks full. Reproducible: Always
Created attachment 100411 [details] Memory looks nearly full Added “Memory looks nearly full” attachment. Yet, there is plenty of available memory: % free -h total used free shared buff/cache available Mem: 7,7G 1,8G 198M 380M 5,7G 5,2G Swap: 0B 0B 0B
Git commit 346b492b362a1ee74ea809de80c0cdaa60ef1dda by David Edmundson, on behalf of Miklós Máté. Committed on 19/10/2016 at 21:51. Pushed by davidedmundson into branch 'Plasma/5.8'. Count only applications in memory usage This restores the behavior of the widget to match the original C++ version. Buffers and cached do not really contribute to memory usage, because file system cache gets dropped, if applications need more memory. See MemFree vs. MemAvailable in /proc/cpuinfo.

Created attachment 112373 [details] Screenshot - load viewer plasmoid includes disk cache in used memory This is apparently an issue again. The disk cache is included in used memory. See attached screenshot. Please reopen. Plasma version 5.12.4
> The disk cache is included in used memory. To clarify my point: misrepresented in the visualization of used memory.
Any chance to get this fixed before Plasma 5.13?
What's wrong with visually displaying cache (as green custom color like before), but reporting without adding in cache (like before)? It was not "wrong" and matched (visually) what top and others would report. In other words, why hide the used cache?
I was frustrated to find, after updating KDE the other day, that it no longer shows cache in the memory usage bar. There is another entire bar available for displaying cache, that seems to show something completely different, but there is no way to see the thing I want to see: the portion of memory being used by the file system cache. It used to display cache in a different color to used memory, which was perfect, but now it's gone. If showing cache is potentially confusing, a quick checkbox could be added to make it an off-by-default preference.
Created attachment 122065 [details] Patch To Restore Cache Display and Allow Hover I also submitted a patch to allow hovering on the load viewer so that it wouldn't disappear until moving the mouse off of it. That was rejected on some consistency grounds -- not on its merit. I, too didn't like the change here. But it seems that no one agrees. That being the case, I have been carrying my own patches to restore the cache display and to allow hover to prevent the display from closing. Here are my patches, if you are interested. I apply them (after updates regress them) with the following commands (Fedora): sudo patch /usr/share/plasma/plasmoids/org.kde.plasma.systemloadviewer/contents/ui/SystemLoadViewer.qml ui/SystemLoadViewer.qml.patch sudo patch /usr/share/plasma/plasmoids/org.kde.plasma.systemloadviewer/contents/ui/ColorSettings.qml ui/ColorSettings.qml.patch sudo patch /usr/share/plasma/plasmoids/org.kde.plasma.systemloadviewer/contents/config/main.xml config/main.xml.patch
Is this still an issue or relevant with the new System Monitor applet in Plasma 5.19 and beyond?
(In reply to Nate Graham from comment #9) > Is this still an issue or relevant with the new System Monitor applet in > Plasma 5.19 and beyond? See bug #397840. This bug report is about an existing applet being changed for no apparent reason. Yes this report is relevant because comment #6 was was never addressed before. Bug #397840 contains a patch that fixes the problem in this report, comment #6.

I'm closing this report, since the System Load Viewer is no longer a part of KDE Plasma. My apologies that we weren't able to fix this. For any bugs that are still being encountered, please open a new report. Thanks.
