I want to monitor a PostgreSQL database at the code level, as the documentation indicates.
However, even with the one agent configured and PostgreSQL's Dynatrace plugin
enabled (Image 1), the database is not monitored as expected (Image 2).

In order to see database services you need to install OneAgent also on host where your application is running. Then you should see SQL requests.
