I don't think you want to poll once a day something you bill per day. If
you poll only at noon, and I use a resource from 8:00 to 10:00, you'll
miss my usage and I'll use resource for free. :)

Yes, there's a minimum interval to be configured, but it's the interval
that defined how much grained your metering/billing will be. E.g. if
it's 1 hour, you won't charge anything used for less than one hour. You
probably wants something like 5 minutes or less, and be sure the agent
can keep up with the needed polling speed. :)
