REPORTLOG specifies the report log file for this vendor daemon. It is recommended preceding the report_log_path with a + character to append logging entries; otherwise, the file is overwritten each time the daemon is started.
REPORTLOG [+]report_log_path [HIDE_User]
On Windows, path names that include spaces have to be enclosed in double quotes. If lmgrd is started as a service, the default location for the report log file is the current working directory unless a fully qualified path is specified. The optional parameter [HIDE_USER] can be specified so that any user names will be SHA2 hashed before being written to the encrypted REPORTLOG.
Update [Jan 25th, 2020]:
We have no plans to obfuscate user-name while it is being written into server logs because we feel we need this to debug any reported issues. But if companies have to ship their logs for external audit they can use this utility to obfuscate and send it outside their Org ID
