Which Dynatrace app would be best suited to retain the results of a DQL query...

Notebooks are the best tool in Dynatrace for retaining and reusing DQL query results .

They allow users to:

Store DQL queries

Keep query results for later analysis

Combine queries with text, documentation, and visualizations

Share insights across teams

Other options:

Dashboards are for visualization, not query retention

Data Explorer is for ad-hoc analysis

Reports are more static and not designed for iterative DQL workflows
