Semantic Conventions for Tracing Compatibility Components

Status: Experimental

This document defines trace semantic conventions used by the compatibility components, e.g. OpenTracing Shim layer.

OpenTracing

Links created by the OpenTracing Shim MUST set opentracing.ref_type with one of the accepted values, describing the direct causal relationships between a child Span and a parent Span, as defined by OpenTracing.

Attribute	Type	Description	Examples	Requirement Level
opentracing.ref_type	string	Parent-child Reference type [1]	child_of	Recommended

[1]: The causal relationship between a child Span and a parent Span.

opentracing.ref_type MUST be one of the following:

Value	Description
child_of	The parent Span depends on the child Span in some capacity
follows_from	The parent Span does not depend in any way on the result of the child Span
