Select the master or slave for which logging needs to be enabled. Select the parameter Enable Log File
and press Save. The default log file location is /var/log/. You can change the name and location of the
log file by editing the Log File Name parameter. However certain locations are not writable by the
MultiSmart unit and hence /tmp/, /var/log/, /media/usb/ and /media/sd/ are the best locations for
saving the log file. /media/usb/ refers to the USB and /media/sd/ refers to the SD card. By using these

the PgUp and PgDn buttons. If the Auto button is pressed, new log messages are dynamically updated to
the screen, which eliminates the need for scrolling. Once in Auto mode, you can switch back to manual
mode by pressing the Manual button, which will prevent the new messages to be automatically displayed on
the screen. This mode is useful when analyzing log messages in more detail.
