size
This attribute can be used only for memory. The memory size is fetched from
the vCenter Server and replicated in the vCenter Chargeback Manager
database by the data collector synchronization jobs.
burstable utilization
This attribute lets you account for the 95th percentile of actual utilization. This
attribute is available only for the external network transmit rate and external
network receive rate computing resources.
Base Rate
Base rate is a global rate that you want to charge for a unit of chargeable computing resource used, reserved,
or allocated for a specific duration.
Table 5-1 lists a set of sample base rates for a unit of each chargeable computing resource.
Table 5-1. Sample Base Rate Values
Chargeable Resource Unit Duration Base Rate ($)
CPU GHz Hourly 0.0399
Memory GB Hourly 0.0048
Network Received and Transmitted GB/hour Hourly 0.0008
Storage GB Hourly 0.0013
Disk Read and Write GB/hour Hourly 0.0008
vCPU Count Hourly 0.04
The base rate duration is configurable. vCenter Chargeback Manager lets you define the base rate for an hour,
day, week, month, quarter, half-year, or year for each computing resource. The precision for a base rate value
is four digits.
In the case of time zones with daylight savings time, if you configure an hourly rate for a resource, then the
cost of the resource for a day is accounted for either 23 hours or 25 hours, as applicable. However, daylight
saving days are considered as full days and a daily cost configured for a resource is charged entirely and not
adjusted based on the number of hours in the daylight saving day. Similarly, the weekly, monthly, quarterly,
half-yearly, and yearly rates are considered in entirety and not adjusted for daylight savings.
For example, if you configure an hourly rate of $1 for a resource, then the total cost for the resource for a day
would be either $23 or $25 based on the date. However, if you configure a daily rate of $10 for a resource, the
cost of the resource for a day is accounted as $10 for any day of the year.
Rate Factor
Rate factor is the multiplication factor to be used along with the base rate to calculate the charge for a unit of
chargeable computing resource used or allocated for a specified duration. Rate factors are useful when you
want to charge the entities in a hierarchy differently.
The rate factors enable you to apply a cost that is a multiple or a fraction of the base rate. The rate factor value
can be between 0 and 999.99. The precision is up to two decimal places.
Table 5-2 lists sample base rates, rate factors, and the total cost for a unit of the chargeable computing resource
consumed, reserved, or allocated.
Table 5-2. Sample Base Rates and Rate Factors
Chargeable Resource Base Rate ($) Rate Factor Total Charge ($)
CPU 0.0399 1.1 0.0439
Memory 0.0048 1.1 0.0053
