KDE System Guard, also known as KSysGuard, was the task manager and performance monitor for the KDE platform on Unix-like systems.

It can retrieve simple values or complex data such as tables and display this information in a variety of graphical displays.

Displays can then be organized in work sheets.

It also provides a detailed top-like process table.

Recently this has become unmaintained[3] and Plasma System Monitor[4] has been taken as the replacement.
