Metered Resource Pricing Setup Wizard (sample):
Step 1: Determine the WAP Usage Resource and its unit (Raw Usage unit)
Each WAP Resource’s Raw Usage is expressed in different units. This unit is decided by the Resource Provider that generates that usage. Cloud Assert Usage & Billing product depends upon these Raw Usage values, to calculate the bill and invoice of each customer.
One might need to refer to the Resource Provider’s documentation to know this unit.
Example WAP Resources:

Step 2: Set the Unit Multiplier
Decide the units in which to charge the customers and accordingly set the Unit Multiplier. This Unit Multiplier is multiplied with the Raw Usage, to generate the resulting units (Billable Units) upon which pricing is calculated.
Calculated Units or Billable Units = Raw Usage value * Unit Multiplier
For instance, if the Raw Usage unit is expressed in Mega Bytes, and if you decide to setup the Monthly Pricing based on Giga Bytes, then the Unit Multiplier will be 1/1024 expressed in decimals.

Step 3: Monthly Unit Price - Set the price per month based on above units
Monthly Unit Price is the price equivalent for usage of ‘1 unit / hour’ of usage for 720 hours (24 hours * 30 days). Based on this value, Hourly Unit Price is calculated internally by Cloud Assert Usage & Billing product and used to calculate the net cost of a customer’s per hour usage of a WAP Resource.
Usage Cost @ a hour = [Billable Units @ that hour] * [Hourly Unit Price]
Usage Cost @ a hour = Raw Usage value * Unit Multiplier * Monthly Unit Price / 720

From the rows (1) and (2), we can observe that even when ‘Calculated Hourly Units’ and ‘Hourly Unit Price’ are different, the ‘Calculated Hourly Price’ stays same if the usage is same.
