Monitoring System Resources from the Gnome Desktop

Monitoring System Resources

You'll be pleased to know that most Linux distros provide a GUI application to monitor resources (-equivalent to the Windows Task Manager). For Ubuntu, this is called the System Monitor and it can be invoked from:

System → Admin → System Monitor:

Invoke System Monitor (Gnome)

For Ubuntu 11.04 onwards, you can find it by right-clicking the "Power" icon (Power Icon) amongst the "System Settings":

Invoke System Monitor (Unity)

For Fedora, you can find the same tool by searching for the string "mon" in the Activities area:

Invoke System Monitor (Fedora)

A dialogue box will open up containing multiple tabs:

System Monitor Tabs

If you click on the "Processes" tab, you'll see the processes currently running: click on any of the headings to sort by that heading. If you wish to stop any of the processes, simply click on that process to select it, then click the "End Process" button:

System Monitor Process Tab

If you click on the "Resources" tab, you'll see an overview of how the system is currently performing: check for any peaks up to around 100% in the graphs, which may indicate problems:

System Monitor Resources Tab

If you click on the "File Systems" tab, you'll see a display showing how full your various filesystems are. In the example below, this system in running low on space in it's /boot filesystem - which may need some Housekeeping performed on it:
