You can view operating system information. The Event Viewer utility displays a list of log files, which are files that list the activities of the system facilities, such as daemon, printer, kernel, or printer facilities.
You can set up filters to specify which log files you want to view. The Event Viewer generates the list of log files based on your filter specifications. You can view log files for the following facilities: Authorization, Crontab, Daemon, Kernel, Printer, Mail, News, Syslog, UUCP, and PPP. You can refresh the list to access the most current log files. You can specify log dates to allow the Event Viewer to overwrite events if the event has recurred after the specified date. For example, if you set log dates to 20 days, a warning message for the Kernel facility that is 20 or more days old is overwritten by a new warning message, if the same warning message is logged. Turning overwrite log dates off prevents log files from being overwritten.
You can access read-only information about available system devices; the information is stored in the /proc/devices directory.
