Hi @gilles_tabary
Planning and estimating DDU consumption for custom metrics, such as those from extensions like Microsoft Exchange Server and Active Directory Services in Dynatrace, involves understanding the metric generation rate and applying it to the DDU cost model.
Exchange
- If the "Metric Metadata 35" means it generates 35 metrics per minute, this is your starting point.
- Annual DDU Calculation:
- 35 metrics/minute
- Each metric is reported every minute
- 60 minutes in an hour
- 24 hours in a day
- 365 days in a year
- 0.001 DDU is the cost per metric
Formula: Metrics/minute×minutes/hour×hours/day×days/year×DDU cost/metric
Calculation for "Exchange": 35×60×24×365×0.001
Active Directory Services
You need to determine the number of metrics generated per minute for this extension. Once you have this figure, you can apply the same formula.
- Ensure whether the metric count is an average or represents peak usage, as this will impact the estimate.
- DDUs are typically pooled at the account level in Dynatrace, so consumption across all services and extensions contributes to the total usage.
- It's often prudent to add a safety margin to your estimates to account for unforeseen spikes in data.
DDU consumption for the Microsoft Exchange Server as per your example:
For this extension in Dynatrace, with a rate of 35 metrics per minute, the estimated annual DDU consumption would be approximately 18,396 DDUs. - like you wrote
For planning the DDU consumption for the Active Directory Services extension, you would follow the same approach. First, determine the number of metrics generated per minute by this extension, and then apply the same formula to estimate the annual DDU usage.

Have a nice day!
