System Administration Tools

Now turning attention to, three KDE based system administration tools will be discussed:

  • A tool to monitor system performance and processes,

  • A network interface administration tool and

  • A user administration tool.

These tools can be launched from the K menu -> System or the gnome footprint menu->KDE->System in the left side of the task bar. These tools may have slightly different names depending on the distribution. System administrator or root permissions may be needed to launch or perform many of these functions. If so, you may be prompted for the root password as these applications are being launched.

The next two figures show an example of two views of the system processes and performance using KDE System Guard.

Figure 357 is a view of all the processes that are running on the system. The order in which these processes are presented can be changed by clicking on the top of any column. So to order the processes by their percentage of CPU use, click on the column heading System%. Processes can be killed by highlighting or clicking on the desired process and then stop or kill it by clicking on the Kill button in the lower right hand corner of the window. Although any user may be able launch KDE System Guard, the user could only kill processes that they own; it would take administrator or root privileges to be able to kill other processes

Figure 358 is a graphical view of the system load and memory usage, a very informative way of viewing how the system is functioning. Obviously when the administrator sees that swap usage been excessive, then adding more ram to the system would be appropriate and likewise if the load average or CPU load is staying at an excessively high level a processor upgrade may be in order.
