Log to Disk - Controls whether or not MOVEit Central writes its log file to disk. (The scrolling display on the Log tab of MOVEit Central Admin is not affected by this setting.)
Global Debug Level - Controls how much information is logged to disk and is displayed in the "Log" tab if no task filter is set.
Log Filename - Controls the name of the log file. The default value is "MoveITC.log". If no path is provided, the file will be written out to the same folder in which MOVEit Central has been installed. A complete file path (e.g., "D:\moveit\logs\central.log") can be used to write the log file on another drive. A file will only be written if "Log to Disk" is "yes".
Maximum Log File Size - Controls how big log files are allowed to grow before they are automatically rolled. (Old log files are retained for one generation as ".old" files. Only applies if "Log to Disk" is "yes")
