Way back when ... Hughes had data limits and the FAP policy but had no way to measure usage ...
A member here and at dslreports forum (that predates the Official Hughes forum that you see here)
wrote a very simple, very light on recourses, "usage meter" that is real time, as it takes its info from the modem itself.
It kind of "lost its place" as newer Hughes systems came on line but it works very well with the 7000s system and the "legacy" 9000 with DAILY refill.
Where it really shines ... and may be a benefit to you, is that you can have everything (as far as you know) closed, and can hover your mouse over its systray icon and SEE the refill "drip" occur.
If you have everything closed and not see a "minute by minute" gain, then you are alerted to a "leak" if you will.
Don Bradner's HNFapalert can be found in a link near the bottom of this page:
Its free, its "real time" and for a 7000 system you just can't ask for anything more.
It is so "light" you need not remove any "official" Hughes meters, and the legacy "usage history page" you posted before is just fine as a cross-check.
I used Don's meter for years without problems prior to switching to a HT1100 Gen4 system.
If you have any questions, drop me a line here, at the dslr Hughes forum linked above or at the 'Shack where I'm a Mod:
