external network receive computing resources. For all other resources, the user-
defined allocation units is considered for cost calculation. This billing policy is
set in the VMware Cloud Director Pay As You Go - Resource Based Charging
Cost Model.
VMware Cloud Director
Billing Policy - Networks
This billing policy is available only if the VMware Cloud Director Data
Collector is installed. This policy takes in to account the actual usage for
external network transfer and external network receive computing resources.
For all other resources, the user-defined allocation units are considered for cost
calculation. This billing policy is set in the VMware Cloud Director Networks
Cost Model.
In vCenter Chargeback 1.5, you can also define your own billing policies.
Cost Model
A cost model defines base rates for the chargeable computing resources, the currency, the billing policy to be
used for calculating the total cost, and special costs, such as cost for the guest operating system installed on
the virtual machine. A cost model also enables you to define different billing policies for different time periods.
After you define a cost model in the application, you can define rate factors and fixed costs on entities or
hierarchies for the selected cost model. You can also use the cost model to generate various reports.
Cost Template
A cost template consists of entity-specific cost configuration details. These are rate factors for the chargeable
computing resources and the fixed costs.
You can set these values in a cost template and use the template to configure the costs at the entity level.
Managing Cost Models
vCenter Chargeback provides a default cost model called Default Chargeback Cost Model. The cost models
defined in the application can be viewed and managed from the Cost Models page of the Manage Cost tab.
You can start using the application by creating a chargeback hierarchy and generating basic reports using this
cost model. You can modify this cost model as per your requirements. You can also create and manage multiple
other cost models.
If you have installed the VMware Cloud Director Data Collector, vCenter Chargeback provides five more cost
models:
n
VMware Cloud Director Allocation Pool Cost Model
n
VMware Cloud Director Reservation Pool
n
VMware Cloud Director Pay As You Go - Fixed Charging Cost Model
n
VMware Cloud Director Pay As You Go - Resource Based Charging Cost Model
n
VMware Cloud Director Networks Cost Model
These cost models do not define any base rates or fixed costs. You must modify the cost models and set the
required base rates and fixed costs before using them for generating reports.
N
OTE
If you define and include fixed costs in these cost models, ensure that you modify the corresponding
billing policies and select the Add/Include Fixed Cost option.
