2.2. GNOME System Monitor
The GNOME desktop environment includes a graphical tool, System Monitor, to assist you in monitoring and modifying the behavior of your system. System Monitor displays basic system information and allows you to monitor system processes and resource or file system usage.
System Monitor has four tabs, each of which displays different information about the system.
- System
- This tab displays basic information about the system's hardware and software.
- Processes
- This tab displays detailed information about active processes and the relationships between those processes. The processes displayed can be filtered to make certain processes easier to find. This tab also lets you perform some actions on the processes displayed, such as start, stop, kill, and change priority.
- Resources
- This tab displays the current CPU time usage, memory and swap space usage, and network usage.
- File Systems
- This tab lists all mounted file systems, and provides some basic information about each, such as the file system type, mount point, and memory usage.
To start System Monitor, press the Super key to enter the Activities Overview, type System Monitor, and then press Enter.
For more information about System Monitor, see either the Help menu in the application, or the Red Hat Enterprise Linux 7 System Administrator's Guide.
