Service graph

Service Graphs provide a visual representation of service interactions, dependencies, and performance metrics. Service graphs are built by analyzing span relationships and require specific span attributes.

To have a service graph or to improve the quality of the existing service graph, consider adding the following attributes.

General attributes

• service.name is an attribute that represents the logical name of the service. Required.
• _kind (span_kind) categorizes the type of work being represented by the span. Make sure your traces have client/server or producer/consumer span pairs. Required.
• _status_code (span_status_code) provides information about the result of a specific operation or unit of work represented by this span. This attribute helps to monitor and understand the success, failure, or other conditions of a given operation. Recommended.

RPC calls

• rpc.service represents the full (logical) name of the service being called. Optional.

DB calls

• db.name contains the name of the database being accessed. Recommended if you have multiple databases.

HTTP calls

• server.socket.domain represents the domain name of an immediate peer. Required for HTTP calls.
• server.socket.address represents the physical server IP address or Unix socket address. Required for HTTP calls if server.socket.domain is not provided.

Messaging calls

• messaging.destination.name is the message destination name, for example, MyQueue, MyTopic.
• messaging.client_id is a unique identifier for the client that consumes or produces a message.
• messaging.kafka.consumer.group is the name of the Kafka Consumer Group that is handling the message. Only applies to consumers, not producers.
