Monitor FTP Bytes Transfer in IIS 6.0

FTP Server in IIS 6.0 does not log information about the size of data transfer and hence we can not find out the data tranfer size in W3 logs. To enable the logging of data transfer size in FTP logs , chage following settings in IIS :-
--> Right click on FTP Site
-> Click on Properties
--> Ensure that Enable Logging is checked and click on Properties button
--> Click Advanced tab
--> Select the bytes sent & bytes received check box.

These settings will enable FTP logging along with downloading and uploading bytes details.
