•using public cloud on-demand pricing versus term pricing
While many comparisons work out-of-the-box, you need to configure cost models for certain comparisons, such as:
•migration to another vCenter location. For example, to compare costs for your production and development lab on vCenter, configure distinct cost models for the production and development lab levels of your infrastructure.
•migration from vCenter to SCVMM. In this case, you can use the Default Private Cloud cost model for vCenter, and configure a distinct cost model for SCVMM.
By default, the report includes data for all VMs for which at least one billing record was generated during the period. Templates are not included in the report.
Report data is based on costs from billing records, which are generated nightly. The costs in the VM billing records, in turn, are calculated from the VM at the time the billing records are written, and from the relevant cost model values. See Configuring Cost Models for details.
By default, this report uses historical data. If the managed system was added to Embotics® vCommander® recently, retrieving historical data (supported for vCenter and AWS only) will provide more data for this report. When historical data is retrieved, vCommander automatically generates billing records for the retrieval period. If no historical data is available, the report provides options to use current data with projections (except in the case of AWS). To learn how to retrieve historical data, see:
|When you include off-premise cost models in the comparison, you must use the default currency setting ($ - Dollar). Public cloud pricing is set to US dollars, and vCommander cost comparisons will not convert or use rates for currencies other than the default.|

During: Specify a time period for the report.
•When you select By Period, the period will be the last completed day, week, month, quarter or year. For example, if the current month is May and you select Last 3 Months, the range for the report will be February, March and April. See Using Date Filters for Reporting and Searching for more information.
•When you select By Dates, vCommander prepopulates the earliest date available for selection, which is the date when the first managed system was added to vCommander.
Cost Model: Generate VM costs for the Current Location based on:
•Historical costs — Use both the cost model and VM resource usage from the billing records. With this option, VM uptime is taken from the nightly billing records.
|When an AWS managed system is used as the Current Location, this option uses AWS billing data, if available.|
•Current costs — Show costs as though the current cost model were in effect for the specified timeframe, but take VM resource usage from the historical billing records. This option allows you to change your cost model but still use the actual VM resource usage from the billing records. With this option, VM uptime is taken from the nightly billing records.
•Projected costs — This is the default option. It shows costs as though the current cost model and current VM resource usage were in effect for the specified timeframe. Only VMs that currently exist are included in the report. With this option, VM uptime is set to 100% for currently running VMs and to 0% for currently powered-off VMs.
This option is especially useful if you've just installed vCommander or if you've just added a managed system to vCommander and there is no historical data.
Current Location: Use the tree to narrow down the set of VMs that are compared (for example, choose a managed system or your Production infrastructure).
Projected Destination: Use the tree to choose a projected destination for cost calculation. You can choose from:
•Operational: Use the Operational view to choose a location in one of your connected managed systems.
•VMs and Templates: Use the VMs and Templates view to choose a location in one of your connected managed systems. Note that cost models targeting the Operational view always take precedence over cost models targeting the VMs and Templates view.
•Supported Cloud Costs: Choose from the default cost models for supported clouds, plus any cost models you've configured.
•Other Cloud Costs: Choose from the cost models for unsupported public clouds.
For public cloud destinations, you may need to navigate down to the Region level. If you're not sure which region to select, select the one closest to you geographically.
Recommendations: Specify whether rightsizing recommendations are included in the cost calculations. You can choose all recommendations, only upsizing recommendations, or only downsizing recommendations.
•If the Current Location is in an public cloud managed system: Rightsizing recommendations are not generated for public cloud VMs. Selecting an option in the Recommendations drop-down menu has no effect on the report.
•If the Projected Destination is in an off-premise managed system: vCommander calculates costs by predicting the best-match instance type. For example, if vCommander has recommended downsizing a VM to 1 vCPU and 0.6 GB memory and you are projecting costs on AWS, costs will be calculated as if the VM had a Micro instance type in the AWS managed system.
Results in single table: By default, results are shown in multiple tables. If you are only calculating the benefit of applying rightsizing recommendations (meaning that Current Location and Projected Destination are the same), displaying the results in a single table makes more sense. If you select Yes, the single table is labeled Current and Projected. Note that this option only has an effect if rightsizing recommendations are applied to the report (that is, the Recommendations option is set to something other than None).
Uptime Percentage: Choose to show or hide the Uptime (%) column in the report. By default, this column is hidden. This column displays the uptime percentage for each VM in the report. VM uptime affects report costs if any costs have been set to be calculated only while VMs are running.
VM uptime calculations are related to the Cost Model report option. When the Cost Model option is set to Current costs or Historical costs, VM uptime is taken from the nightly billing records. When the Cost Model setting is set to Projected costs, by contrast, VM uptime is set to 100% for currently running VMs and to 0% for currently powered-off VMs.
|Upgrade note: Billing records created before the introduction of the VM uptime feature are considered to have an uptime percentage of 100% for reporting purposes.|
Costs will be calculated based on VM uptime if either the source cost model or the destination cost model have cost elements that apply only when the VM is running.
Group By: There are several ways to group the report data (for example, you can group by cost center). Grouping affects only the two VM Costs to Date tables.
Add Advanced Filters: You can filter the report by VM name, custom attributes and ownership.
When filtering by a custom attribute, vCommander retrieves the list of all VMs which existed in the location targeted by the report during the reporting period. Records for any VM for which there is no billing record are discarded. Then, records for any VMs that did not have the selected custom attribute applied on at least one of the following points in time are discarded:
•The first day of the reporting period
•The day the VM was created
•The day the VM was deleted
•The last day of the reporting period
This means that it's possible for VMs with the filtering attribute applied on other dates to be excluded from the report.
Once the rows are filtered to VMs with the filtering attributes applied on one of these dates, the complete billing records for the reporting period will be displayed, whether or not the attribute was applied for the entire period.

|This example is shown below under Example VM Comparative Economics Report: Rightsizing.|
The report calculates whether migrating and/or rightsizing the VMs will provide cost savings. For migration assessment, the report shows you costs for the length of the period, for the current location and the projected location side-by-side, with tables and graphs showing cost breakdown. The recommended location is indicated. The report also displays the projected savings for the period.
|All public cloud costs are estimates and are intended for planning purposes only.|
For rightsizing recommendations, the report shows you costs for the VMs prior to and after applying the recommendations. The RECOMMENDED and NOT RECOMMENDED labels are not displayed if you are assessing only rightsizing recommendations (that is, you have not selected a Projected Destination).
When not all VMs have billing records for the entire specified timeframe, the message "Complete billings records not available for all VMs" is displayed.
VM cost details are provided under "Current" and "Projected". The Days column represents the number of days that a billing record was generated for the VM.
You may see a table at the bottom of the report titled "VMs Without Billing Records". This table includes:
•VMs that have been managed by vCommander for less than a day
•VMs for which vCommander has no historical events
Because vCommander can't guarantee that the storage tier associated with a VM's datastore will match a storage tier for a datastore in the new location, vCommander always calculates projected costs based on the current storage tier.
If the projected destination has no available datastore on the same storage tier, the following warning is displayed under the Report Parameters section:
Note: Storage tier(s) <list of missing storage tiers> do not exist at the projected location.
If you pick a current location or projected destination where the storage tier information is not available (that is, a destination other than a resource pool or compute resource/cluster), then vCommander does not verify that the storage tiers are available at the projected destination.
