Documentation

Overview

Package cloudtrace provides access to the Cloud Trace API.

For product documentation, see: https://cloud.google.com/trace

Creating a client

Usage example:

import "google.golang.org/api/cloudtrace/v2"
...
ctx := context.Background()
cloudtraceService, err := cloudtrace.NewService(ctx)

In this example, Google Application Default Credentials are used for authentication.

For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.

Other authentication options

By default, all available scopes (see "Constants") are used to authenticate. To restrict scopes, use option.WithScopes:

cloudtraceService, err := cloudtrace.NewService(ctx, option.WithScopes(cloudtrace.TraceAppendScope))

To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey:

cloudtraceService, err := cloudtrace.NewService(ctx, option.WithAPIKey("AIza..."))

To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource:

config := &oauth2.Config{...}
// ...
token, err := config.Exchange(ctx, ...)
cloudtraceService, err := cloudtrace.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

See https://godoc.org/google.golang.org/api/option/ for details on options.

                Link: A pointer from the current span to another span in the same trace or in a different trace.

                            func (*ProjectsTracesBatchWriteCall) Header

                              Header returns an http.Header that can be modified by the caller to add HTTP headers to the request.

                              func (r *ProjectsTracesService) BatchWrite(name string, batchwritespansrequest *BatchWriteSpansRequest) *ProjectsTracesBatchWriteCall

                                BatchWrite: Sends new spans to new or existing traces. You cannot update existing spans.

                                func (*ProjectsTracesSpansCreateSpanCall) Context

                                  Context sets the context to be used in this call's Do method. Any pending HTTP request will be aborted if the provided context is canceled.

                                  func (*ProjectsTracesSpansCreateSpanCall) Do

                                    Do executes the "cloudtrace.projects.traces.spans.createSpan" call. Exactly one of *Span or error will be non-nil. Any non-2xx status code is an error. Response headers are in either *Span.ServerResponse.Header or (if a response was returned at all) in error.(*googleapi.Error).Header. Use googleapi.IsNotModified to check whether the returned error was because http.StatusNotModified was returned.

                                          func New(client *http.Client) (*Service, error)

                                            New creates a new Service. It uses the provided http.Client for requests.

                                            Deprecated: please use NewService instead. To provide a custom HTTP client, use option.WithHTTPClient. If you are using google.golang.org/api/googleapis/transport.APIKey, use option.WithAPIKey with NewService instead.

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 may be gaps or overlaps between spans in a trace.

                                                        Status: The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC (https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the API Design Guide (https://cloud.google.com/apis/design/errors).
