Set up Cost & Carbon Optimization

To set up Cost & Carbon Optimization Cost & Carbon Optimization, open the app for the first time and turn on Enable energy and emission data generation.

You will be redirected to Cost & Carbon Optimization Cost & Carbon Optimization once the last hour of data is calculated.

To deactivate data generation, select in the upper-right corner to open Settings, and then turn off Enable energy and emission data generation.

Data storage and retention

Cost & Carbon Optimization Cost & Carbon Optimization calculates cost and emissions data every hour.

  • The first data point of energy consumption and emissions is created from the last hour after data generation is activated.
  • Generated data is stored in Grail with a default retention period of 35 days. You can adjust this retention time by creating a custom bucket based on the event.types defined in the Dynatrace Semantic Dictionary.

Data schema

The data generated by Cost & Carbon Optimization Cost & Carbon Optimization follows the schema defined in the Dynatrace Semantic Dictionary.

Data units

The units of data generated are as follows

  • Electricity consumption is calculated in watt-hours (Wh).
  • Carbon dioxide emission is calculated in grams (g) but displayed in charts on the landing page in kilograms (kg).
  • Public price list cost data uses USD.

Settings

Select in the upper-right corner of the page to access the settings.

You can deactivate the energy and emission data generation from here.

Notify on workflow failure

You can activate notifications in case a workflow fails. You'll receive email with details of the problem.

Enable price list costs data generation

  1. AWS and Azure expose their public price list data on open APIs, but Google Cloud requires an API key to collect their public price list data. Follow the instructions to enable the API and get an API key.
  2. Select Test connection to verify that all outbound connections are defined and the Google Cloud API key is valid.
  3. Enable price list costs data.
  4. Scroll down and select Save.

Optimization options

The Settings page offers two optimization options.

  • Idling optimization—enables you to detect hosts that are turned on and running but not actively used or performing tasks.

  • Sizing optimization—enables you to detect hosts that are not idle but use fewer resources than initially planned. You can also make changes to their configuration.

In both cases, you need to set parameters that define a host as idle or underutilized. Default values are based on Google Cloud criteria.

  • An idle host:

    • Uses less than 3% of CPU.
    • Has outgoing network traffic below 100.000 bytes/s or incoming network traffic below 120.000 bytes/s.

  • An underutilized host:

    • Uses more than 3% and less than 30% of CPU.
    • Uses less than 50% of memory.

You can adjust the values to your requirements.

Business health performance indicator

You can define a business health performance indicator of your choice, derived from any of your captured business events.

For example, your business health performance indicator could be the total revenue generated by all the orders completed in a purchase process that is captured as business events containing an attribute for the revenue value. This KPI is displayed compared to carbon emissions in the Carbon vs business KPI chart in the lower-right corner of the app landing page.

To set up a Business health performance indicator

  1. Select app Settings Settings in the upper-right corner and scroll to the Business health performance indicator section.
  2. Select the business event (Select event) on which you want to base your business health performance indicator or Key Performance Indicator (KPI).
  3. optional Select the KPI from the list of available attributes (Select KPI). The listed attributes change based on the event selected. If no KPI is selected, the business health performance indicator is calculated as the count of business events.
  4. Define the unit of the KPI to be displayed in charts and single-value tiles. This unit is displayed in the right Y-axis of the Carbon vs business KPI chart. Be sure to use a unit that matches your selected KPI and limit the length of the string so that it's displayed correctly in the chart.
  5. Save your settings.
