- Published Feb 01, 2022
A SaaS deployment has one active license that controls the products you can use. Products include host units, host unit hours, Digital Experience Monitoring, Davis data units, and Application security units. Account Management provides a real-time view of licensed product consumption (Total license usage), with historical analysis at the daily or hourly level (Usage details).
This page is provided for informational purposes only. The terms of the Dynatrace free trial offer and/or your Dynatrace license will be applied to any use of Dynatrace products or services. For more information, see License Dynatrace.
Total license usage
The Total license usage section shows real-time information on how your license is being consumed.
-
Each licensed product is shown as a separate infographic, indicating how much of each product you have used.
-
The product infographics indicate license quota usage as a number (for example, 100 / 1k) and as a percent used.
The product infographics use color to indicate status:
- Blue indicates that your usage is below your quota
- Yellow means you have exceeded your quota and you are now incurring overages (if allowed)
- Red indicates that your maximum quota has been reached and monitoring is disabled
Hover over a product infographic to display a detailed breakdown of usage.
Usage details
Use the Usage details charting to explore the historical consumption of your license by selecting the relevant Product, Resolution, and Timeframe options.
Resolution
Resolution allows you to view consumption data in different ways:
- Daily – provides day-by-day total usage
- Hourly – view hourly cumulative totals for a selected day
- Total – view cumulative usage for consumption-based licenses (host unit hours, Digital Experience Monitoring, Davis data units, Application security units)
- Linear forecast – view forecast usage based on linear extrapolation from the last 30 days of usage data (Digital Experience Monitoring and Davis data units only).
- Seasonal forecast – view total forecast usage based on a seasonal forecast from the last 365d of data (Digital Experience Monitoring and Davis data units only).
Filter
Use the filter above the chart to control which environments to view.
Environment usage breakdown table
Changing chart options will update the Environment usage breakdown table below the chart. The table represents total consumption by environment based on your Product and Timeframe selections.
Export
Select 
Export data to download charted data as a CSV format file, which can be helpful for additional tabular reports and aggregation.
Quotas and overages
If your account is eligible for splitting host unit quotas, Account Management displays a License > Quotas and overages menu option.
Customers with a SaaS deployment of Dynatrace can split their host unit quota across multiple environments and control whether an environment can consume host unit hour overages.
This is not available for Dynatrace Platform Subscription customers.
The Quotas and overages page displays the total host units available and lists the tenants in the table below, indicating each tenant's assigned host unit quota.
You must have the View and manage account and billing information permission to access this page.
Changing the assigned host unit quota for any environment will update the total host units assigned, displayed at the top of the page. The total host units assigned value must equal the total host units available before you can save changes.
If your license allows overages, but the overages are capped, you’ll see a May consume host unit hours option box for each environment. Select this setting to allow authorized users to enable overages for mission-critical environments and production servers that have high load.
Environments with this option enabled will incur additional host unit hour charges when usage exceeds the host units quota; otherwise, environments may not exceed their Assigned host unit quota.
When host unit limits are reached
When the configured limit for concurrent host units for an environment is reached–assuming that the account is not entitled to use overages—Dynatrace begins enforcing the available limit.
Enforcing a limit on concurrent host units means that Dynatrace decides which hosts to continue monitoring and for which host monitoring will be stopped. The decision is based on the start times of the OneAgents installed on the monitored hosts. When the limit is reached, Dynatrace disables monitoring on the most recently started OneAgents that exceed the concurrent host unit limit.
Example: Let’s assume a configured limit of six concurrent host units for each environment, and the following hosts with installed OneAgents:
| Monitored host | OneAgent start time | Size (GB) | Host units | Concurrent host units |
|---|---|---|---|---|
| Host 1 | 2022-Jan-04 01:12am | 32 GB | 2 | 2 |
| Host 2 | 2022-Jan-04 02:43am | 48 GB | 3 | 5 |
| Host 3 | 2022-Jan-04 11:18pm | 16 GB | 1 | 6 |
| Host 4 | 2022-Jan-05 10:12am | 32 GB | 2 | 8 (monitoring disabled) |
| Host 5 | 2022-Jan-05 10:13am | 16 GB | 1 | 9 (monitoring disabled) |
When the OneAgents on Host 4 and Host 5 start reporting data, the configured limit of 6 concurrent host units is exceeded. At that point, Dynatrace disables monitoring of these two hosts and continues monitoring Hosts 1-3.
Frequently asked questions (FAQs)
Why does Consumption usage details not match total license usage?
- License usage provides an accurate and real-time measurement of how much license has been consumed, and differentiates between free, paid, and overage usage.
- Consumption usage details provides a historic breakdown of total consumption that includes paid, free and overage units, and may not therefore match the License Usage.
When should I use Linear vs. seasonal forecast?
- If you are a new customer, you may have to rely on the linear model until you have a full year of consumption history to predict a better model. The linear model is also accurate if your past 30 days of usage are more indicative of your future usage.
- If your business is more seasonal (for example, retail spikes during holiday periods) and you have a year or more of consumption data, the seasonal model can provide a better estimate of future use.
What Host unit quota limit is shown in the usage details?
The shown quota limit is the overall quota limit on the contract, including all your environments.
