Traces Context

The Traces Context is a Context implementation for pdata Traces, the collector's internal representation for OTLP trace data. This Context should be used when interacted with OTLP traces.

Paths

In general, the Traces Context supports accessing pdata using the field names from the traces proto. All integers are returned and set via int64. All doubles are returned and set via float64.

The following fields are the exception.

path	field accessed	type
resource	resource of the data point being processed	pcommon.Resource
resource.attributes	resource attributes of the data point being processed	pcommon.Map
resource.attributes[""]	the value of the resource attribute of the data point being processed	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
instrumentation_scope	instrumentation scope of the data point being processed	pcommon.InstrumentationScope
instrumentation_scope.name	name of the instrumentation scope of the data point being processed	string
instrumentation_scope.version	version of the instrumentation scope of the data point being processed	string
instrumentation_scope.attributes	instrumentation scope attributes of the data point being processed	pcommon.Map
instrumentation_scope.attributes[""]	the value of the instrumentation scope attribute of the data point being processed	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
attributes	attributes of the data point being processed	pcommon.Map
attributes[""]	the value of the attribute of the data point being processed	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
trace_id.string	a string representation of the trace id	string
span_id.string	a string representation of the span id	string
trace_state[""]	an individual entry in the trace state	string
status.code	the status code of the span being processed	int64
status.message	the status message of the span being processed	string

Enums

The Traces Context supports the enum names from the traces proto.
