Span Context

The Span Context is a Context implementation for pdata Spans, the collector's internal representation for OTLP span data. This Context should be used when interacted with OTLP spans.

Paths

In general, the Span 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.

All TraceIDs and SpanIDs are returned as pdata SpanID and TraceID types. Use the SpanID function and TraceID function when interacting with pdata representations of SpanID and TraceID. When checking for nil, instead check against an empty byte slice (SpanID(0x0000000000000000) and TraceID(0x00000000000000000000000000000000)).

The following paths are supported.

path	field accessed	type
cache	the value of the current transform context's temporary cache. cache can be used as a temporary placeholder for data during complex transformations	pcommon.Map
cache[""]	the value of an item in cache. Supports multiple indexes to access nested fields.	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
resource	resource of the span being processed	pcommon.Resource
resource.attributes	resource attributes of the span being processed	pcommon.Map
resource.attributes[""]	the value of the resource attribute of the span being processed. Supports multiple indexes to access nested fields.	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
resource.dropped_attributes_count	number of dropped attributes of the resource of the span being processed	int64
instrumentation_scope	instrumentation scope of the span being processed	pcommon.InstrumentationScope
instrumentation_scope.name	name of the instrumentation scope of the span being processed	string
instrumentation_scope.version	version of the instrumentation scope of the span being processed	string
instrumentation_scope.dropped_attributes_count	number of dropped attributes of the instrumentation scope of the span being processed	int64
instrumentation_scope.attributes	instrumentation scope attributes of the span being processed	pcommon.Map
instrumentation_scope.attributes[""]	the value of the instrumentation scope attribute of the span being processed. Supports multiple indexes to access nested fields.	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
attributes	attributes of the span being processed	pcommon.Map
attributes[""]	the value of the attribute of the span being processed. Supports multiple indexes to access nested fields.	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
trace_id	a byte slice representation of the trace id	pcommon.TraceID
trace_id.string	a string representation of the trace id	string
span_id	a byte slice representation of the span id	pcommon.SpanID
span_id.string	a string representation of the span id	string
parent_span_id	a byte slice representation of the parent span id	pcommon.SpanID
parent_span_id.string	a string representation of the parent span id	string
trace_state	the trace state of the current span	string
trace_state[""]	an individual entry in the trace state	string
status	the status of the span being processed	ptrace.Status
status.code	the status code of the span being processed	int64
status.message	the status message of the span being processed	string
name	the name of the span	string
kind	the kind of the span	int64
start_time_unix_nano	the start time in unix nano of the span	int64
end_time_unix_nano	the end time in unix nano of the span	int64
dropped_attributes_count	the dropped attributes count of the span	int64
events	the events of the span	ptrace.SpanEventSlice
dropped_events_count	the dropped events count of the span	int64
links	the links of the span	ptrace.SpanLinkSlice
dropped_links_count	the dropped links count of the span	int64

Enums

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

SPAN_KIND_UNSPECIFIED	0
SPAN_KIND_INTERNAL	1
SPAN_KIND_SERVER	2
SPAN_KIND_CLIENT	3
SPAN_KIND_PRODUCER	4
SPAN_KIND_CONSUMER	5
