Reference documentation and code samples for the Stackdriver Trace V2 Client class Span.
A span represents a single operation within a trace. Spans can be nested to form a trace tree. Often, a trace contains a root span that describes the end-to-end latency, and one or more subspans for its sub-operations.
A trace can also contain multiple root spans, or none at all. Spans do not need to be contiguous. There might be gaps or overlaps between spans in a trace.

__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ name
string
Required. The resource name of the span in the following format: * * projects/[PROJECT_ID]/traces/[TRACE_ID]/spans/[SPAN_ID]
[TRACE_ID]
is a unique identifier for a trace within a project; it is a 32-character hexadecimal encoding of a 16-byte array. It should not be zero. [SPAN_ID]
is a unique identifier for a span within a trace; it is a 16-character hexadecimal encoding of an 8-byte array. It should not be zero. .
↳ span_id
string
Required. The [SPAN_ID]
portion of the span's resource name.
↳ parent_span_id
string
The [SPAN_ID]
of this span's parent span. If this is a root span, then this field must be empty.
↳ display_name
TruncatableString
Required. A description of the span's operation (up to 128 bytes). Cloud Trace displays the description in the Cloud console. For example, the display 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 within an application and at the same call point. This makes it easier to correlate spans in different traces.
↳ start_time
Google\Protobuf\Timestamp
Required. 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.
↳ end_time
Google\Protobuf\Timestamp
Required. 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.
↳ attributes
↳ stack_trace
↳ time_events
Span\TimeEvents
A set of time events. You can have up to 32 annotations and 128 message events per span.
↳ links
↳ status
↳ same_process_as_parent_span
Google\Protobuf\BoolValue
Optional. Set this parameter to indicate whether this span is in the same process as its parent. If you do not set this parameter, Trace is unable to take advantage of this helpful information.
↳ child_span_count
Google\Protobuf\Int32Value
Optional. The number of child spans that were generated while this span was active. If set, allows implementation to detect missing child spans.
↳ span_kind
int
Optional. 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 an RPC call.
getName
Required. The resource name of the span in the following format:
-
projects/[PROJECT_ID]/traces/[TRACE_ID]/spans/[SPAN_ID][TRACE_ID]is a unique identifier for a trace within a project; it is a 32-character hexadecimal encoding of a 16-byte array. It should not be zero.
[SPAN_ID]
is a unique identifier for a span within a trace; it
is a 16-character hexadecimal encoding of an 8-byte array. It should not
be zero.
.
string
setName
Required. The resource name of the span in the following format:
-
projects/[PROJECT_ID]/traces/[TRACE_ID]/spans/[SPAN_ID][TRACE_ID]is a unique identifier for a trace within a project; it is a 32-character hexadecimal encoding of a 16-byte array. It should not be zero.
[SPAN_ID]
is a unique identifier for a span within a trace; it
is a 16-character hexadecimal encoding of an 8-byte array. It should not
be zero.
