# Application Observability service map

The service map uses the [Tempo Metrics-generator](/docs/tempo/latest/metrics-generator/) and the [Node Graph panel](/docs/grafana/latest/panels-visualizations/visualizations/node-graph/#navigating-the-node-graph) to display a graph of related services.

Nodes represent services, for example, an API or database. Edges represent relationships between services.

## Nodes

Select a node to view details about the service:

- Service name
- Average response time
- Average request rate

Right-click a **node** to view a context menu of options to:

- Navigate to the service inventory list and show the service
- Navigate to the [service overview](/docs/grafana-cloud/monitor-applications/application-observability/manual/service)
- View the traces for the service in **Explore**

The node color represents the percentage of requests in each state:
