To view the system log of the American server, you can use the logs provided by the system to view the tool. In the Linux system, the log files in the/var/log directory are usually used to record the system activity. Here are some common methods to view system logs:

　　Use the CAT or Less command: You can use the cat or less command to view the contents of the log file. For example, check the system log file (usually/var/log/syslog), you can run:

　　cat/var/log/syslog

　　Or use less to view in an interactive manner:

　　less/var/log/syslog

　　You can use the arrow key to roll up the log content up and down, and exit the less by pressing Q.

　　Use the tail command: TAIL command is used to view the end of the log file, which is usually used to monitor log files in real time. For example, to monitor the new entry of the log file of the system, you can run:

　　tail -F/VAR/LOG/SYSLOG

　　This will display new log entries in real time in the terminal. Press Ctrl+C to stop monitoring.

　　Use specific log files: Systems usually record different types of logs into different files, for example, security -related logs are usually recorded in /var/log/auth.log. You can use the same Cat, LESS or TAIL command to view other log files.

　　Use a log viewer tool: You can also use graphical log viewer tools, such as Gnome-System-Log or KsystemLog (suitable for GNOME and KDE desktop environment). These tools provide a more friendly interface to easily filter and search logs.

　　Use Journalctl (for system log): On the Linux system using SystemD, you can use the Journalctl command to view the system log. For example:

　　Journalctl

　　By default, it shows the nearest system log entry. You can use different options to filter and search log content.

　　Use a log rotation tool: The system usually uses a log rotation tool to manage log files to ensure that they will not grow infinitely. These tools will back up and delete the old log files to save disk space. Common tools include Logrotate.

　　Please check the system logs of the American server according to your needs and system configuration. Different Linux distributions and system versions may be slightly different, but the above methods can usually be applied.
