-- Lists Amazon GuardDuty usage statistics over the last 30 days for the
-- specified detector ID. For newly enabled detectors or data sources, the
-- cost returned will include only the usage so far under 30 days. This may
-- differ from the cost metrics in the console, which project usage over 30
-- days to provide a monthly cost estimate. For more information, see
-- <https://docs.aws.amazon.com/guardduty/latest/ug/monitoring_costs.html#usage-calculations Understanding How Usage Costs are Calculated>.
