Semantic conventions for GraphQL server spans

Status: Development

Status: Development

This span represents an incoming operation on a GraphQL server implementation.

Span name SHOULD be of the format {graphql.operation.type} provided graphql.operation.type is available. If graphql.operation.type is not available, the span SHOULD be named GraphQL Operation.

Warning The graphql.operation.name value is provided by the client and can have high cardinality. Using it in the GraphQL server span name (by default) is NOT RECOMMENDED.

Instrumentation MAY provide a configuration option to enable a more descriptive span name following {graphql.operation.type} {graphql.operation.name} format when graphql.operation.name is available.

Span kind SHOULD be SERVER.

Span status SHOULD follow the Recording Errors document.

Attribute Type Description Examples Requirement Level Stability
graphql.document string The GraphQL document being executed. [1] query findBookById { bookById(id: ?) { name } } Recommended Development
graphql.operation.name string The name of the operation being executed. findBookById Recommended Development
graphql.operation.type string The type of the operation being executed. query; mutation; subscription Recommended Development

[1] graphql.document: The value may be sanitized to exclude sensitive information.


graphql.operation.type has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
