The system logging interface is used to extract detailed debugging information for the Mantis system. It can also serve as an audit trail for user actions.
This controls the type of logging information recorded. Possible values include:
logs issue id, message type and recipients for all emails sent
logs the details of email recipient determination. Each user id is listed as well as why they are added, or deleted from the recipient list
specifies the file where the log data goes. This file must be writable by the web server userid running mantis. Right now, only "file:<file path>" is supported. For example, $g_log_destination = 'file:/tmp/mantis_log'; See http://www.php.net/error_log for details.
