4 - APM Downstream Dependencies
This map shows all services sending traces and the interactions between them. Each arrow represents a service calling a specific operation in another service. The legend in the arrows includes the requests per second for that interaction.  If you are downsampling your traces before sending them to Promscale, then the number of requests per second will not be accurate but you'll be able to see how it compares to other operations.
APM Overview dashboard offered by Promscale on top of traces by leveraging SQL and TimescaleDB capabilities.

This dashboard contains:

1. **Map of Downstream Dependencies**  representing nodes and edges here nodes are services and edges are connections between services. This panel represents all downstream dependencies for the selected service and operation.
