To view system log files in an interactive, real-time application, use the Log Viewer. To start the application, go to the Main Menu Button (on the Panel) => System Tools => System Logs , or type the command redhat-logviewer at a shell prompt.
The application only displays log files that exist; thus, your list might differ from the one shown in Figure 1-1. To view the complete list of log files that it can view, refer to the configuration file, /etc/sysconfig/redhat-logviewer.
