Specified by:

getTraceId

public com.google.protobuf.ByteString getTraceId()

 A unique identifier for a trace. All spans from the same trace share
 the same `trace_id`. The ID is a 16-byte array. An ID with all zeroes OR
 of length other than 16 bytes is considered invalid (empty string in OTLP/JSON
 is zero-length and thus is also invalid).

 This field is required.

bytes trace_id = 1;

Specified by:: getTraceId in interface SpanOrBuilder
Returns:: The traceId.

getSpanId

public com.google.protobuf.ByteString getSpanId()

 A unique identifier for a span within a trace, assigned when the span
 is created. The ID is an 8-byte array. An ID with all zeroes OR of length
 other than 8 bytes is considered invalid (empty string in OTLP/JSON
 is zero-length and thus is also invalid).

 This field is required.

bytes span_id = 2;

Specified by:: getSpanId in interface SpanOrBuilder
Returns:: The spanId.

getTraceState

public java.lang.String getTraceState()

 trace_state conveys information about request position in multiple distributed tracing graphs.
 It is a trace_state in w3c-trace-context format: https://www.w3.org/TR/trace-context/#tracestate-header
 See also https://github.com/w3c/distributed-tracing for more details about this field.

string trace_state = 3;

Specified by:: getTraceState in interface SpanOrBuilder
Returns:: The traceState.

getTraceStateBytes

public com.google.protobuf.ByteString getTraceStateBytes()

 trace_state conveys information about request position in multiple distributed tracing graphs.
 It is a trace_state in w3c-trace-context format: https://www.w3.org/TR/trace-context/#tracestate-header
 See also https://github.com/w3c/distributed-tracing for more details about this field.

string trace_state = 3;

Specified by:: getTraceStateBytes in interface SpanOrBuilder
Returns:: The bytes for traceState.

getParentSpanId

public com.google.protobuf.ByteString getParentSpanId()

 The `span_id` of this span's parent span. If this is a root span, then this
 field must be empty. The ID is an 8-byte array.

bytes parent_span_id = 4;

Specified by:: getParentSpanId in interface SpanOrBuilder
Returns:: The parentSpanId.

getName

public java.lang.String getName()

 A description of the span's operation.

 For example, the name can be a qualified method name or a file name
 and a line number where the operation is called. A best practice is to use
 the same display name at the same call point in an application.
 This makes it easier to correlate spans in different traces.

 This field is semantically required to be set to non-empty string.
 Empty value is equivalent to an unknown span name.

 This field is required.

string name = 5;

Specified by:: getName in interface SpanOrBuilder
Returns:: The name.

getNameBytes

public com.google.protobuf.ByteString getNameBytes()

 A description of the span's operation.

 For example, the name can be a qualified method name or a file name
 and a line number where the operation is called. A best practice is to use
 the same display name at the same call point in an application.
 This makes it easier to correlate spans in different traces.

 This field is semantically required to be set to non-empty string.
 Empty value is equivalent to an unknown span name.

 This field is required.

string name = 5;

Specified by:: getNameBytes in interface SpanOrBuilder
Returns:: The bytes for name.

getKindValue

public int getKindValue()

 Distinguishes between spans generated in a particular context. For example,
 two spans with the same name may be distinguished using `CLIENT` (caller)
 and `SERVER` (callee) to identify queueing latency associated with the span.

.opentelemetry.proto.trace.v1.Span.SpanKind kind = 6;

Specified by:: getKindValue in interface SpanOrBuilder
Returns:: The enum numeric value on the wire for kind.

getKind

public Span.SpanKind getKind()

 Distinguishes between spans generated in a particular context. For example,
 two spans with the same name may be distinguished using `CLIENT` (caller)
 and `SERVER` (callee) to identify queueing latency associated with the span.

.opentelemetry.proto.trace.v1.Span.SpanKind kind = 6;

Specified by:: getKind in interface SpanOrBuilder
Returns:: The kind.

getStartTimeUnixNano

public long getStartTimeUnixNano()

 start_time_unix_nano is the start time of the span. On the client side, this is the time
 kept by the local machine where the span execution starts. On the server side, this
 is the time when the server's application handler starts running.
 Value is UNIX Epoch time in nanoseconds since 00:00:00 UTC on 1 January 1970.

 This field is semantically required and it is expected that end_time >= start_time.

fixed64 start_time_unix_nano = 7;

Specified by:: getStartTimeUnixNano in interface SpanOrBuilder
Returns:: The startTimeUnixNano.

getEndTimeUnixNano

public long getEndTimeUnixNano()

 end_time_unix_nano is the end time of the span. On the client side, this is the time
 kept by the local machine where the span execution ends. On the server side, this
 is the time when the server application handler stops running.
 Value is UNIX Epoch time in nanoseconds since 00:00:00 UTC on 1 January 1970.

 This field is semantically required and it is expected that end_time >= start_time.

fixed64 end_time_unix_nano = 8;

Specified by:: getEndTimeUnixNano in interface SpanOrBuilder
Returns:: The endTimeUnixNano.
