The Backup Exec Debug Monitor, or SGMon, is a diagnostic tool that captures debug output from Backup Exec and saves it in debug logs. SGMon debug logs can help you troubleshoot backup issues. Furthermore, debug logs can help Symantec Technical Support diagnose and repair problems.
When you open SGMon, it automatically captures debug data from Backup Exec's services. To collect debug information while SGMon is closed, enable debug log creation outside of SGMon and specify a directory in which to save the logs.
For more information about how to configure the Debug Monitor and read log files, refer to the help within the Debug Monitor.
