Log_App configuration parameter (ACS)
Syntax (prefix with dash in a Generation Settings Scheme):
Log_App=<path and name of file>
Where <path and name of file> specifies the path and file name of the log file.
The Log_App configuration parameter specifies a log file in which to record ACS log messages. When ACS starts, log messages are appended to the specified file.
Examples
Log_App=c:\Logs\MyLog.txt
