This defines the name of the log file. All logging messages are time stamped and written to this file. Each time this file is written to by Radiator, it opens, writes, and then closes the file. This means that you can safely rotate the log file at any time. The file name can include special path name characters. For more information about special characters, see Section 3.3. Special formatters. The default is %L/logfile, i.e. a file named logfile in LogDir. For more information, see Section 3.7.12. LogDir.

Here is an example of using LogFile and special characters:

# Log file goes in /var/log, with year number
LogFile /var/log/%Y-radius.log

You can disable all logging to the log file by setting LogFile to be the empty string:

# Disable logging to log file completely
LogFile

If the file name starts with a vertical bar character | then the rest of the filename is assumed to be a program to which the output is to be piped. Otherwise the output is appended to the named file.

# Pipe to my-log-prog
LogFile |/usr/local/bin/my-log-prog
