The maximum of usage and reservation is not calculated by comparing the total
used units for the entire reporting duration against the total reserved units for
the entire reporting duration. vCenter Chargeback Manager compares the used
and reserved units for each sample available for the specified reporting
duration to calculate the total units to be charged. The samples are fetched from
the vCenter Server database. vCenter Server provides samples for the following
time slices: 5 minutes, 30 minutes, 2 hours, and 1 day.
vCenter Chargeback Manager uses the largest time slice sample available to
calculate the maximum of used and reserved units. For example, if a report is
generated for a week using this billing policy, then for calculating the total CPU
and memory units to be charged, vCenter Chargeback uses the daily sample
for each day of the week and compares the used units for each day with the
reserved units of that day and accounts for the maximum of the two. If for any
days of the week the daily samples are unavailable, then vCenter Chargeback
Manager uses the 2 hour samples only for those days to calculate the total CPU
and memory units to be charged.
All fixed costs are ignored. The expression for the billing policy is as follows:
cpu = max(usage, reservation);
memory = max(usage, reservation);
other resources = usage;
Maximum of CPU Usage
and CPU Reservation
In this policy, the maximum of used and reserved units of CPU along with the
actual utilization of other chargeable computing resources is considered for
calculating the total cost. The total CPU units to be charged is calculated in the
same way as specified for the Maximum of Usage and Reservation billing
policy. All fixed costs are ignored. The expression for the billing policy is as
follows:
cpu = max(usage, reservation);
other resources = usage;
Maximum of Memory
Usage and Memory
Reservation
In this policy, the maximum of used and reserved units of memory along with
the actual utilization of other chargeable computing resources is considered for
calculating the total cost. The total memory units to be charged is calculated in
the same way as specified for the Maximum of Usage and Reservation billing
policy. All fixed costs are ignored. The expression for the billing policy is as
follows:
memory = max(usage, reservation);
other resources = usage;
Fixed Cost and Actual
Usage
This policy takes into account all the fixed costs associated with an entity and
the actual utilization of the chargeable computing resources by the entity for
calculating the total cost. The expression for the billing policy is as follows:
other resources = usage;
fixed costs = include;
Fixed Cost and
Allocation
This policy takes into account all the fixed costs associated with an entity and
the user-defined allocations units set on the entity for the chargeable computing
resources when calculating the total cost. The expression for the billing policy
is as follows:
other resources = allocation;
fixed costs = include;
