In KDE Plasma, when you run an application (eg: Dolphin) with a shortcut (Meta+E), it is not listed in "System Monitor" - "Overview" - "Application". But the same application: If you open it in Panel, Menu or ".desktop" file on Desktop, it will be listed under "System Monitor" - "Overview" - "Application".
This applies to Autostart. So if you set an application to start automatically when KDE Plasma is started, the application you want to start automatically is not listed under "System Monitor" - "Overview" - "Application".
I think this situation is not normal.
A little note: This also applies when you start with "Konsole".
Applications are not listed in System Monitor if they are launched via shortcut (eg: Meta+E) or command line.
No matter how apps are run, they should be listed in System Monitor.

They key difference is whether or not the app is launched with its own cgroup, because the Applications page in System Monitor only knows about cgrouped apps. That's how it knows something is an app and not some random system process. When you run an app's binary directly (i.e you run `kate` inside a terminal window), it's up to you to make sure that happens, since you're running the app by hand.
However when running an app via a global shortcut, this should be happening. I can reproduce the issue. Moving to the kglobalaccel framework.
I thought we already a bug somewhere tracking this,
but it depends on if klauncher is runnign or not. If not we are using kstart5, probably should reverse that
