Summary

This chapter discussed some of the system administration utilities provided in the Ubuntu workstation. The System Monitor allows you to monitor and control processes running on the system, as well as view the current CPU, memory, network, and disk utilization on that system.

The System Log Viewer provides an easy way to view all of the log files available in the Ubuntu workstation from a single window. You can view those log files, plus look at the daily log files from separate days that are stored on the system.

The Services Settings window allows you to view and change which system services are started when the system boots. You can select which services start, what system runlevel they start in, and the priority (order) in the runlevel that they start.

Separate from the Services Settings window, the Sessions Preferences window allows you to configure the individual applets and programs that automatically start when you log into your desktop. The Sessions Preferences window provides options for selecting which applets and programs start, for viewing which applets and programs are currently running in your session, and for saving your session settings so that the same applets and programs start the next time you log in.

The last section of this chapter discussed how to use the Disk Usage Analyzer tool. This tool helps you identify the areas in a filesystem that use the most amount of disk space. The Disk Usage Analyzer scans a disk area (or the entire disk) and provides a graphical treemap of the results. Each ring on the treemap represents a folder level in the filesystem hierarchy. Folders at the same level in the same ring are depicted with sizes relative to the amount of disk space they use.

In the next chapter we'll take a look at the Ubuntu command line. The command-line interface can come in handy when trying to administer your system because it's often quicker to enter commands than to interact with a graphical tool.
