One shows CPU load, the second shows memory and swap usage and the third shows total system network utilization. The built-in 'System Load' tab will show you three nice graphs. The KDE System Monitor process list with some additional information such as IO Read and IO Write enabled. Those 'Tools' are just launchers for konsole, the KDE Info Center, kmag, htop and 'Run Command'. The process list has a little button called Tools on the right side. The process list can list all processes as list or a tree, system processes only, user processes only, only your own processes and programs only. Interesting additional columns that are available, but not shown by default, include IO Read, IO Write, X11 Memory, CPU time and CGroup. Right-clicking on the row of column titles brings up a list of additional information that can be shown about each of the listed processes. The 'Process table' view shows a list of processes, similar to top and htop, with a limited amount of details. There are two tabs available, one is called 'Process Table' and the other is called 'System load'.

The KDE System Monitor looks very plain when you first open it.

Its functionality can be expanded using a wide variety of downloadable plugins. It has two default tabs for showing a process list and system load graphs by default. The KDE System Monitor ( ksysguard) is a task manager and system monitoring program made with the KDE Plasma desktop environment in mind.
