Use the Service Map

The Service Map visualizes your environment as a graph of interconnected nodes. Each node represents a service or an external resource, and the connections between them represent the flow of requests.

• Nodes - Represent services, or external services (e.g., frontend, productcatalogservice, google.com).
• Connections - Represent the traffic between services. The direction of the flow indicates the caller-callee relationship.
• Health Indicators - Nodes are color-coded based on their current health status.

Navigating the Map

You can access the Service Map by navigating to Services > Map in the primary navigation sidebar.

Map Settings

Customize your view using the Map Settings panel to focus on the data most relevant to your investigation:

• Layout - Choose between a Flow layout (hierarchical view showing traffic from left to right) or a Force directed layout (organic grouping of related services).
• External services - Group or ungroup external dependencies (like third-party APIs or cloud services) to reduce visual clutter. Or hide them all completely.
• Show particles on connections - Enable animated particles to visualize the volume of request rates between services.
• Metric Selection - Choose which metric to visualize on the nodes. You can select various different metrics for requests, errors or durations.
• Size nodes by metrics - When enabled, the physical size of the node scales based on its request volume or error count.

Filtering and Searching

Use the search bar at the top of the map to filter for specific services. You can create complex filters using attributes like service.nameCopy to isolate specific sub-systems or microservice clusters.

Service Details and Drill-down

Clicking on any node in the map opens the Service Details sidebar. This panel provides a deep dive into the telemetry of the selected service without leaving the map context.

Summary and Infrastructure

The sidebar displays the service's resource attributes, such as runtime environment, Kubernetes deployment details (Namespace, ReplicaSet), and Cloud provider information (AWS Account, Region, Availability Zone).

Health and RED Metrics

• Failed checks - View recent alerts or synthetic check failures affecting the service.
• RED Metrics - High-level charts showing Request total, Error percentage, and Duration average to provide context needed for quick troubleshooting.

Operations and Resources

• Operations - A breakdown of the service's operations. For example, specific RPC or HTTP methods (e.g., GetProductCopy, ListProductsCopy), with their individual request counts, error rates, and average durations.
• Resources - Shows the health and performance of the underlying infrastructure, such as specific Kubernetes pods.

Saved Views

Dash0 allows you to save specific map configurations for quick access:

• Built-in views - Default views provided by Dash0.
• Your views - Custom-filtered maps that you have saved. To save a view, apply your desired filters and settings, then click Save as at the top of the screen. This is ideal for creating dedicated dashboards for specific applications.
