An OpenTelemetry Tracer that can be used for building spans.
Abstract Value Members
- abstract def contextFromGrpcThreadLocalContext(): TelemetryContext
Returns a telemetry context from the OpenTelemetry context stored in the gRPC thread local context.
Returns a telemetry context from the OpenTelemetry context stored in the gRPC thread local context. This is used to recover the tracing metadata from an incoming gRPC call, and used for the subsequent spans.
- abstract def contextFromMetadata(metadata: Option[Map[String, String]]): TelemetryContext
Returns a telemetry context from the metadata encoded in the given key-value map.
Returns a telemetry context from the metadata encoded in the given key-value map.
Typically, the metadata map has been encoded in a message, which has been sent across boundaries, from a different process. Originally, it has been created to carry tracing metadata across boundaries, and to create complete traces.

- abstract def contextFromOpenTelemetryContext(context: Context): TelemetryContext
Allows to transform an Open Telemetry context into a telemetry context.
Allows to transform an Open Telemetry context into a telemetry context. Makes integration easier for consumers that are using the Open Telemetry API directly. Consider using other factory methods.
- context
raw Open Telemetry context
- abstract def rootContext: TelemetryContext
Returns a new root context for this implementation of Telemetry.
Returns a new root context for this implementation of Telemetry.
Any span create from this context should be the first span of a new trace.
