Resource summary computation

Hi all,

please, can anybody explain me how is resource summary measured in Chargeback?

In my resource usage report I have a detail of virtual RAM usage (see numbers below) which is measured hourly.

On top of the report there is "Resource summary" table showing total usage of 24,97 GB of RAM.

How Chargeback got this number? Can anybody explain in detail please?

Thank's a lot!

There are multiple cost models that provide flexibilty in measuring costs.

vCenter Chargeback supports three different cost models:
1. Fixed cost – specific per virtual machine instance costs such as floor space, power/cooling, software or administrative overhead
2. Allocation-based costing – Variable costs per virtual machine based on allocated resources, such as the amount
of memory, CPU or storage allocated or reserved for the virtual machine in vCenter Server
3. Utilization-based costing – Variable costs per virtual machine based on actual resources used, including average memory, disk and CPU usage, network I/O and disk I/O Cost models can be combined in a cost template, making it easy to start with a simple chargeback model and align with organizational requirements.
