VMware VCENTER CHARGEBACK 1.5 - API Manual de usuario descargar pdf (Pagina 8)

A chargeback solution for a virtual environment defines a hierarchy with different types of entities such as

departments, divisions, business units, cost centers, physical servers, virtual machines, and so on. For each

entity type, a cost model is defined that determines the rate for each unit of a resource utilized. The chargeback

solution determines the resource usage by using either utilization-based metering or allocation-based metering

of virtual machines. The metered parameters are then associated with the designated entities, and the cost

model defined for that entity along with specific chargeback formulas are used as part of the overall chargeback

solution.

Overview of vCenter Chargeback Manager

Determining the resource utilization and calculating the corresponding cost for a virtual environment that uses

VMware vSphere typically involves VMware professional services’ work or use of partner solutions. These

solutions are built using custom methods for VMware vSphere resource data collection and chargeback cost

calculation for organizations.

vCenter Chargeback Manager is an end-to-end cost reporting solution for virtual environments that use

VMware vSphere. This Web-based application interacts with the vCenter Server Database to retrieve usage

information, calculates the cost by using the defined chargeback formulas, and generates cost and usage

reports. Figure 1-1 shows how vCenter Chargeback Manager interacts with various components of a virtual

environment using VMware vSphere.

vCenter Chargeback Manager runs on an Apache Tomcat server instance. Users interact with vCenter

Chargeback Manager through a load balancer (Apache HTTP Server). vCenter Chargeback Manager connects

to the vCenter Chargeback Manager database that stores application-specific information, such as the defined

chargeback hierarchies, cost models, users, roles, and so on. The application interacts with the vCenter Server

using VIM APIs and with the vCenter Server database through a data collector. The data collector

communicates with the vCenter Server Database using JDBC.
