28.2. Viewing Log Files
Most log files are in plain text format. You can view them with any text editor such as Vi or Emacs. Some log files are readable by all users on the system; however, root privileges are required to read most log files.
To view system log files in an interactive, real-time application, use the Log Viewer. To start the application, go to Applications (the main menu on the panel) => System Tools => System Logs, or type the command system-logviewer at a shell prompt.
The application only displays log files that exist; thus, the list might differ from the one shown in Figure 28-1.
To filter the contents of the log file for keywords, type the keyword(s) in the Filter for text field, and click Filter. Click Reset to reset the contents.
By default, the currently viewable log file is refreshed every 30
seconds. To change the refresh rate, select
Edit =>
Preferences from the pulldown menu. The
window shown in Figure 28-2
appears. In the Log Files tab, click the up and down
arrows beside the refresh rate to change it. Click
Close to return to the main window. The refresh
rate is changed immediately. To refresh the currently viewable file
manually, select File => Refresh
Now or press
On the Log Files tab in the Preferences, the log file locations can be modified. Select the log file from the list, and click the Edit button. Type the new location of the log file or click the Browse button to locate the file location using a file selection dialog. Click OK to return to the preferences, and click Close to return to the main window.
