4.5 Log File
Engineering and LMU logs can be found in the Linux file system. You can find the most recent log
file in a specific
/var/log/ directory, in a file named messages
If you would like to view new information that is written to this log file, Linux offers a way to do
this through the command line.
• Enter: tail –F /var/log/messages
This command will open the messages file and display the latest written lines of the file. It will
continue to display the most updated lines you quit.
Helpful Tip: Linux allows the option to create multiple instances of SSH windows so you can have
one SSH session viewing a log while the other is being used to send AT commands. Other Linux
options such as parsing specific debug using a grep command can also be utilized. For example,
the command:
tail –F /var/log/messages | grep VBU will display lines in the log that have VBU in
the string.
Important Note: The log file stored in ‘messages’ gets overwritten on every device wake-up.
4.6 Backup Logs
There is a method to store a current log file into a backup directory. This can be programmed in
the PEG Script by using
PEG Action 144.
• PEG Action 144 modifier 1 will save the current log into the /data/backup/ folder
• PEG Action 144 modifier 2 will save the current log and also send it to the set remote debug
server defined in param 2328.
Important Note: Only one backup file can be stored at a time
