I am unable to find anything on the roadmap for Azure Databricks.
However, I had a look on the Azure documentation and it mentioned the ability to send Azure Databricks application logs using Log4j. In the new Log Monitor, Dynatrace offers generic log ingestion and log4j2 can be easily integrated directly to stream log directly from Databricks to Dynatrace.
I hope this helps. If you're looking for another ability to monitor Databricks I recommend to raise a product idea when the new Community is launched.
