Created attachment 186868 [details] A screenshot of System Monitor with various programs open and such SUMMARY Hello! The KDE Plasma System Monitor application does not have any support for ZFS. I would like to request implementation of support. There are two issues as a result of no ZFS support. First, System Monitor cannot and does not report the total storage used in the system. In the attached screenshot, note the "Disks" widget does not report anything but the total size of the disk. Other components of KDE like ex. the file manager are able to accurately report the amount of space remaining, however, so this seems like just an issue with System Monitor not handing ZFS. (while a total amount of remaining storage would be good enough, it *would* be cool if System Monitor could produce `zpool list` / `zfs list` inspired output...) Second, System Monitor is unaware of ZFS's usage of available RAM for caching. I'm not sure of the details here, but I think that there is likely some more accurate reporting that could be done were it ZFS-aware? I suppose if ZFS ram caching is reported as "Cache Memory" then it's fine, but I haven't verified that it is. STEPS TO REPRODUCE 1. Install KDE on an operating system with a ZFS root. 2. Open System Monitor. SOFTWARE/OS VERSIONS Linux: Arch Linux 6.12.51-1-lts KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.2 ADDITIONAL INFORMATION Searching the tracker, there are several related bugs. - #433804 (zfs support in ksysguard / system monitor widgets) - #420018 (Hard Disk Space Widget/Plasmoid cannot show ZFS datasets) - #504733 (Disk usage broken on striped ZFS root) This is pretty much a duplicate of #433804. It's filed under an unmaintained component however, so I'm opening a new one here (and suggest #433804 should be closed).
