Cumulative savings and investments charts

Scale actions

Savings and investments are the total of all past scaling actions, with the exception that a scale in one direction (such as a scale up) reduces the amounts of previous actions in the opposite direction (such as a scale down), until one or more previous actions have no more effect.

To illustrate, consider three consecutive scale actions for a newly discovered VM and the effect of these actions on the calculated costs. Note that these actions are assumed to have been executed at midnight. Costs are calculated proportionately when actions are executed at other times of the day.

Investment is the difference between the after-action cost on a particular day and the lowest ever before-action cost up to that day ($2 for all three days in the example). Savings is the difference between the largest ever before-action cost up to a particular day ($5 on Days 02 and 03) and the after-action cost on that day.

Turbonomic reads the daily billing report from the cloud provider to determine the current daily cost of an entity. Calculation also takes into account workload uptime (for VMs) and the effect of consecutive scale actions on the same workload.

Points to consider:

• Calculation can adjust to varying VM uptime and discount coverage over time.

• Calculation stops for terminated entities or entities that Turbonomic no longer discovers.

• Calculation stops if there is a cost change in the entity that is not the result of a Turbonomic action.

Delete actions

Turbonomic checks the daily cost of an entity on the day the entity was deleted, and uses that cost to calculate savings from that day onwards. The daily bill from the cloud provider is not used to calculate savings.

Chart settings

Click the More options icon (), and then select Edit to modify the following settings:

• Scope

  By default, the charts are scoped to your global environment. You can change the scope to one or several accounts, billing families, groups, or entities.

• Timeframe

  • Last 7 Days or Last 30 Days – Each data point in the chart shows total savings or investments from previous days until the given day.

  • Last Year – Each data point in the chart shows total savings or investments from previous months until the given month.

• Chart Type

  You can set the display to:

  • Stacked Bar Chart

  • Area Chart

• Type

  Switch between the Cumulative Savings and Cumulative Investments views. You can also change the displayed data to just Savings or Investments if you do not wish to see how the savings or investment costs accumulate over time.

• Group By

  This setting breaks down data points by the selected group. By default, no group is selected. Each data point only shows the total cumulative values for a given day or month, depending on the selected timeframe.

  The following groups are supported:

  • Account – Cloud accounts discovered in your environment

  • Action type – Scale and delete actions

  • Cloud service provider – AWS, Azure and Google Cloud

  • Entity type – Virtual Machine, Volume, Database (Azure only), Database Server (AWS and Azure only), Document Collection (Azure only), Virtual Machine Spec (Azure only)

  • Region – Regions for the entities

  • Resource group (Azure only) – Available resource groups in your environment

  • Tag – Tag values for a given tag key

    Select a tag key from the list. For AWS, the tag keys are limited to cost allocation tags.

    Note:

    Turbonomic stores and displays tag keys in lowercase. If you use these tags in Turbonomic API requests, specify them in lowercase. Otherwise, the API returns incorrect results.

  For example, if you selected Account:

  • The chart represents each account as a distinct color.

  • When you hover on a data point, the chart shows a list of accounts, ordered from largest to smallest cumulative values.

  • The chart legend shows the individual accounts. Click an account to show/hide values for that account.

  • The chart and legend show up to 20 accounts and, if needed, an additional item labeled 'Others' that represents all accounts that are not in the top 20.
