Web Gateway 5.2 Reporting

I was wondering if there is anyway to get a usage report out of SWG 5.2.  The kind of information I have been asked to source from our Web Gateway are as follows.

How much data has been used over the month by the business.
How much data each user has downloaded over the month.

Is SWG 5.2 able to give me this or will I need a third party tool to get the info out of say a SYSLOG from SWG? 

Currently when you login to the admin console I can see "Raw Traffic Processed" but that is telling me numbers that are surely way off unless it is also counting local intranet sites.etc...

Any help would be greatly appreciated...
