Created attachment 113127 [details] A screenshot of the dialog. Possible duplicate: Bug 127728 This functionality could be useful for profiling and debugging. The info shown in this dialog should be updated periodically. I've submitted a diff for this: https://phabricator.kde.org/D12827 A screenshot of the dialog is attached. Currently it only shows some information from /proc/[pid]/stat and /proc/[pid]/status in the "Statistics" tab (more can be added). The "Open Files" tab makes use of the unused lsofui library in libksysguard.
ksysguard is no longer maintained, in Plasma 6 there is the Plasma system monitor for this task.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!
