Davis data units (DDUs)

Davis data units (DDU) provide a simple means of licensing certain capabilities (custom metrics, log monitoring, and events) on the Dynatrace platform. Think of DDUs as a kind of Dynatrace currency. In the same way that license consumption for Dynatrace RUM and Synthetic Monitoring relies on Digital Experience Monitoring (DEM) units, DDUs provide a seamless, shared consumption model across custom metrics, Log Monitoring, and events.

Because DDUs are consumption-based, you buy a certain volume and your available quota is consumed over time based on the amount of monitoring your environment consumes. This licensing approach makes it much easier for you to control and monitor your metric consumption (for example, in the case of misconfigured metrics) and to identify top consumers in your environment. To learn more about how metrics are licensed with DDUs, see Metric cost calculation.

For complete details about how your Dynatrace monitoring consumption is calculated, see Calculate Dynatrace monitoring consumption.

Davis data unit volumes

DDUs are purchased in volumes of 1 million units based on 1-3 year contract terms, with the full amount of licensed units renewing at the beginning of each year. For example, if you buy 100 million DDUs for a 3-year term, you can consume 100 million DDUs annually for 3 years.

You can purchase additional DDUs at any time if you run low. Reach out to your Dynatrace sales representative for details. To assist you in adjusting your monitoring consumption and avoiding cost overages, in-product notifications are displayed to alert your Dynatrace environment users when 90% and 100% of your licensed DDUs have been consumed.

Davis data units - Free tier

Every new SaaS environment and each Managed license receives 200,000 DDUs free of charge. This translates into 381 metrics, captured at a 1-minute frequency. This free tier enables you to test out features and experience Dynatrace monitoring value before you pay. The free tier of 200,000 DDUs automatically renews annually at the beginning of each new license term for each account (not for Offline accounts).

View DDU consumption details per environment

To see how many DDUs your environment has consumed, go to Settings > Accounting > Davis data units overview. There you can view your DDU consumption and identify the top contributors to DDU consumption.

The Monitored entities tab shows Average DDUs consumption per monitored entity (hosts, services, process groups, applications, or other) per minute. It also shows Consumed DDUs per entity. The number of consumed DDUs shown here is the aggregate of the relevant timeframe, which is displayed above the tabs (1 hour by default). This value reflects any included metrics that are based on host units.
