How do I read the data in my daily email report?

Firebase pricing is sometime based on a daily total, monthly total, or an overall total. Each metric has its own tabulation period. 

The daily email report has a scale indicator and a tabulation period on each row next in the first column.

So for example, “GB/m” is a metric that is measured in Gigabytes per month. Similarly, K/d is thousands per day and GB/t is Gigabytes total.
