FDM Report - Internet Usage

[GDS2023]

I'm trying to generate a usage report from FDM but the numbers are not adding up from what our ISP dashboard is reporting (not even close).   Anyone knows if all internet traffic is being captured by the firewall?  Here is a screenshot from the FDM report but our ISP dashboard is reporting at least 50GB for those date range.

Thanks in advance.

ISP data showing 50GB transfer per day ?

have you looked at the counter on the outgoing interface, may be work using NMS and Graph that interface to see what is consumption overall on the interface.

The 50GB usage on the ISP is the total on the same date range on the FDM report.   We captured the same report in PRTG and it's pretty close to the numbers we see on ISP.   Our objective is to get a usage report per web application.  The Web application report from FDM is exactly what we need but the numbers are way low compare to ISP and PRTG reports.
