You can log all web server HTTP access to the Enterprise Server and the Enterprise Central.
The log on traffic is logged in the httpaccess.log file at the following locations:
Enterprise Server:
C:\ProgramData\Schneider Electric EcoStruxure\Building Operation x.y\Enterprise Server\db\logs
Enterprise Central:
C:\ProgramData\Schneider Electric EcoStruxure\Building Operation x.y\Enterprise Central\db\logs
The log is not created until you enable web server access logging.
