Network Monitor Traffic log

I am looking for a solution to capture traffic volume from Network Monitor on a daily basis. This would be used to identify trends and patterns over a period of time and be able to then compare SMTP/HTTP values associated with those patterns.

I know that I can view these values from the System > Servers > Traffic page, and change the timeframes from All Dates to Today. However, what I am requesting is the ability to pull these daily totals from somewhere and log them as needed. Because the values are stored from these specific date range options - I assume that they're stored somewhere.

Has anyone had experience in pulling these types of metrics - either manually, or by creating a macro to grab the totals from a log source.

Thanks in advance.
