Cloud Trace V2 API - Class Google::Cloud::Trace::V2::Span (v0.9.0)

Reference documentation and code samples for the Cloud Trace V2 API class Google::Cloud::Trace::V2::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.

Methods

#attributes

def attributes() -> ::Google::Cloud::Trace::V2::Span::Attributes
Returns

#attributes=

def attributes=(value) -> ::Google::Cloud::Trace::V2::Span::Attributes
Parameter
Returns

#child_span_count

def child_span_count() -> ::Google::Protobuf::Int32Value
Returns
  • (::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.

#child_span_count=

def child_span_count=(value) -> ::Google::Protobuf::Int32Value
Parameter
  • value (::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.
Returns
  • (::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.

#display_name

def display_name() -> ::Google::Cloud::Trace::V2::TruncatableString
Returns
  • (::Google::Cloud::Trace::V2::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.

#display_name=

#end_time

def end_time() -> ::Google::Protobuf::Timestamp
Returns
  • (::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.

#end_time=

def end_time=(value) -> ::Google::Protobuf::Timestamp
Parameter
  • value (::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.

def links() -> ::Google::Cloud::Trace::V2::Span::Links
Returns

#links=

def links=(value) -> ::Google::Cloud::Trace::V2::Span::Links

Returns
  • (::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. .

#name=

def name=(value) -> ::String
Parameter
  • value (::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. .

Returns
  • (::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. .

#parent_span_id

def parent_span_id() -> ::String
Returns
