Only setting it as major even if it is completely broken, since I don't think remote monitoring is one of the key features.

064688415a1e6db98a3fa20690320596a4f6d3da seems to be the culprit, so adding David to CC.

For some reason it now always passes an empty string as hostname to the Processes constructor, so it will never even try to create a KSysGuard::ProcessesRemote.
Comment 4 Martin Sandsmark 2021-06-17 15:06:55 UTC 
There seems to have been some major refactorings since then with some bad assumptions (e. g. the ExtendedProcesses is for some reason a singleton), so it isn't trivial to fix either.
Comment 6 Christoph Cullmann 2024-09-23 20:59:41 UTC 
ksysguard is no longer maintained, in Plasma 6 there is the Plasma system monitor for this task.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!
