Hi,

May I know what the type of licensing used for instrument application using Dynatrace OpenKit? Will it be Host Unit/DDU/DEM units? Thanks.

Applications instrumented with OpenKit will consume DEM licenses.

Hi&nbsp;[@KeanBoon](https://community.dynatrace.com/user/48887)

I have not used openkit yet but if I’m not mistaken based on the documentation DEM and also DDU can be required for openkit instrumentation. DEM eg. for custom app instumentation or DDU eg. report a business event.

[Dynatrace OpenKit API methods | Dynatrace Docs](https://www.dynatrace.com/support/help/extend-dynatrace/openkit/dynatrace-openkit-api-methods)

I hope it helps.

Best regards,

Mizső

Correct - but it’s only the case if you are using business events, and you are sending data to Grail-enabled SaaS tenant.

All other features consume DEM only.
