"daily or hourly" isn't enough though. There's some AWS resources, like for example route53 hosted zones, which bill only once at the end of the month, and so a daily or hourly bill won't tell you anything about leaked resources there. There's at least a one resource that only bills once a year, so yet again you won't catch those with even monthly usage reports.
