3.2. GNOME and KDE System Monitors
The GNOME and KDE desktop environments both have graphical tools to assist you in monitoring and modifying the behavior of your system.
GNOME System Monitor
The GNOME System Monitor displays basic system information and allows you to monitor system processes, and resource or file system usage. Open it with the gnome-system-monitor command in the Terminal, or click on the menu, and select > .
GNOME System Monitor has four tabs:
- Displays basic information about the computer's hardware and software.
- Shows active processes, and the relationships between those processes, as well as detailed information about each process. It also lets you filter the processes displayed, and perform certain actions on those processes (start, stop, kill, change priority, etc.).
- Displays the current CPU time usage, memory and swap space usage, and network usage.
- Lists all mounted file systems alongside some basic information about each, such as the file system type, mount point, and memory usage.
For further information about the GNOME System Monitor, refer to the menu in the application, or to the Deployment Guide, available from http://access.redhat.com/site/documentation/Red_Hat_Enterprise_Linux/.
KDE System Guard
The KDE System Guard allows you to monitor current system load and processes that are running. It also lets you perform actions on processes. Open it with the ksysguard command in the Terminal, or click on the and select > > .
There are two tabs to KDE System Guard:
- Displays a list of all running processes, alphabetically by default. You can also sort processes by a number of other properties, including total CPU usage, physical or shared memory usage, owner, and priority. You can also filter the visible results, search for specific processes, or perform certain actions on a process.
- Displays historical graphs of CPU usage, memory and swap space usage, and network usage. Hover over the graphs for detailed analysis and graph keys.
For further information about the KDE System Guard, refer to the menu in the application.
