Creates a new span.

Scopes

You will need authorization for at least one of the following scopes to make a valid call:

  • https://www.googleapis.com/auth/cloud-platform
  • https://www.googleapis.com/auth/trace.append

If unset, the scope for this method defaults to https://www.googleapis.com/auth/cloud-platform. You can set the scope for this method like this: cloudtrace2 --scope <scope> projects traces-spans-create-span ...

Required Scalar Argument

  • <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. .

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

Span:
  attributes:
    dropped-attributes-count: integer
  child-span-count: integer
  display-name:
    truncated-byte-count: integer
    value: string
  end-time: string
  links:
    dropped-links-count: integer
  name: string
  parent-span-id: string
  same-process-as-parent-span: boolean
  span-id: string
  span-kind: string
  stack-trace:
    stack-frames:
      dropped-frames-count: integer
    stack-trace-hash-id: string
  start-time: string
  status:
    code: integer
    message: string
  time-events:
    dropped-annotations-count: integer
    dropped-message-events-count: integer

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

  • -r .attributes dropped-attributes-count=79

    • The number of attributes that were discarded. Attributes can be discarded because their keys are too long or because there are too many attributes. If this value is 0 then all attributes are valid.
  • .. child-span-count=68

    • 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 truncated-byte-count=90
    • The number of bytes removed from the original string. If this value is 0, then the string was not shortened.
  • value=ipsum

    • The shortened string. For example, if the original string is 500 bytes long and the limit of the string is 128 bytes, then value contains the first 128 bytes of the 500-byte string. Truncation always happens on a UTF8 character boundary. If there are multi-byte characters in the string, then the length of the shortened string might be less than the size limit.
  • .. end-time=voluptua.

    • 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.
  • links dropped-links-count=74

    • The number of dropped links after the maximum size was enforced. If this value is 0, then no links were dropped.
  • .. name=sanctus

    • 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=sed
    • The [SPAN_ID] of this span's parent span. If this is a root span, then this field must be empty.
  • same-process-as-parent-span=true
    • 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.
  • span-id=amet.
    • Required. The [SPAN_ID] portion of the span's resource name.
  • span-kind=duo
    • 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.
  • stack-trace.stack-frames dropped-frames-count=46

    • The number of stack frames that were dropped because there were too many stack frames. If this value is 0, then no stack frames were dropped.
  • .. stack-trace-hash-id=gubergren

    • The hash ID is used to conserve network bandwidth for duplicate stack traces within a single trace. Often multiple spans will have identical stack traces. The first occurrence of a stack trace should contain both the stackFrame content and a value in stackTraceHashId. Subsequent spans within the same request can refer to that stack trace by only setting stackTraceHashId.
  • .. start-time=lorem

    • 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.
  • status code=89
    • The status code, which should be an enum value of google.rpc.Code.
  • message=eos

    • A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.
  • ..time-events dropped-annotations-count=97

    • The number of dropped annotations in all the included time events. If the value is 0, then no annotations were dropped.
  • dropped-message-events-count=84
    • The number of dropped message events in all the included time events. If the value is 0, then no message events were dropped.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional General Properties

The following properties can configure any call, and are not specific to this method.

  • -p $-xgafv=string

    • V1 error format.
  • -p access-token=string

    • OAuth access token.

  • -p pretty-print=boolean

    • Returns response with indentations and line breaks.
  • -p quota-user=string

  • -p upload-type=string

    • Legacy upload protocol for media (e.g. "media", "multipart").
  • -p upload-protocol=string
