KSysGuard
KSysGuard KSysGuard, also known as KDE System Guard and KDE System Monitor, is designed to make simple process control available to a user without needing to do any special setup.
Installation
KSysGuard is usually installed as part of the KDE Plasma Desktop environment, but can be installed from the Software Center or via terminal:
sudo eopkg it ksysguard
Use KSysGuard as a non-root user
The per process networking plugin requires elevated access to your system. To enable the plugin as non-root user, execute these commands:
sudo setcap "CAP_NET_RAW=+ep" "/usr/lib64/kf5/ksysguard/ksgrd_network_helper"
Usage
KSysGuard User’s Guide or the KDE Help Centre (open khelp on your Plasma Desktop).
