External Network
Transmit Rate
The external network usage for upload measured in MB/hour.
External Network
Receive Rate
The external network usage for download measured in MB/hour.
NOTE The cloud data collectors fetch the external network traffic data only for networks that have a vShield
Edge instance in vShield Manager. An Edge instance is present only if the network is either PRIVATE_ROUTED
ORG NETWORK, ROUTED VAPP NETWORK or FENCED VAPP NETWORK. Therefore, the external
network counters are not charged for other types of vCloud Director networks. Also, the chargeable external
traffic networks are present at org level. Therefore, these counters are not accounted for in reports that are
generated at the vDC level.
Attributes for Accounting Chargeable Computing Resources
The amount of computing resource to be accounted for depends on the attributes defined in the billing policy
expression.
The attributes used by vCenter Chargeback Manager are as follows:
usage
The actual utilization of the resource by the virtual machine. The usage statistics
are collected by the vCenter Server and replicated in the vCenter Chargeback
Manager database by the data collector synchronization jobs. This attribute can
be used only with CPU, memory, storage, disk I/O, network I/O, vCPU, and
external network transmit and receive computing resources. For storage, the
usage attribute indicates the total provisioned storage space for the virtual
machine. For vCPU, the usage attribute indicates the vCPU count.
reservation
The amount of resource reserved for the virtual machine. This reservation is
configured in vCenter Server. Reservation can be defined only for CPU and
memory. The reservation information is replicated in the vCenter Chargeback
Manager database by the data collector synchronization jobs.
allocation
The amount of resource allocated for the virtual machine. This is a user-defined
allocation and is configured in vCenter Chargeback Manager. If you have
integrated a vCloud Director setup with vCenter Chargeback Manager, then
the allocation values that you have defined in vCloud Director are imported in
to vCenter Chargeback Manager by the cloud data collectors. This attribute can
be used with all computing resources except external network transmit and
external network receive. For all the network-related services, such as NAT
service, DHCP service, and full gateway configuration, allocation attribute
indicates whether the corresponding service is enabled or not for the virtual
machine.
Unlike reservation, an allocation value does not assure a minimum resource
availability to the virtual machine. Neither does this value define a maximum
resource utilization. That is to say, the allocation values do not impact the
resource reservation and resource utilization. This attribute is useful when you
want to enforce a minimum amount of resource to be charged, irrespective of
the actual resource utilization or the resource reservation.
