Overview

Package trace is an auto-generated package for the Stackdriver Trace API.

Sends application trace data to Stackdriver Trace for viewing. Trace data is collected for all App Engine applications by default. Trace data from other applications can be provided using this API. This library is used to interact with the Trace API directly. If you are looking to instrument your application for Stackdriver Trace, we recommend using OpenTelemetry.

NOTE: This package is in beta. It is not stable, and may be subject to changes.

General documentation

For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:

Example usage

To get started with this package, create a client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := trace.NewClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := trace.NewClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

req := &tracepb.BatchWriteSpansRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/cloud.google.com/go/trace/apiv2/tracepb#BatchWriteSpansRequest.
}
err = c.BatchWriteSpans(ctx, req)
if err != nil {
	// TODO: Handle error.
}

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

func ProjectPath deprecated

func ProjectPath(project string) string

ProjectPath returns the path for the project resource.

Deprecated: Use

fmt.Sprintf("projects/%s", project)

instead.

func SpanPath deprecated

func SpanPath(project, trace, span string) string

SpanPath returns the path for the span resource.

Deprecated: Use

fmt.Sprintf("projects/%s/traces/%s/spans/%s", project, trace, span)

instead.

Types

type CallOptions

type CallOptions struct {
	BatchWriteSpans []gax.CallOption
	CreateSpan      []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client

type Client struct {

	// The call options for this service.
	CallOptions *CallOptions
	// contains filtered or unexported fields
}

Client is a client for interacting with Stackdriver Trace API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Service for collecting and viewing traces and spans within a trace.

A trace is a collection of spans corresponding to a single operation or a set of operations in an application.

A span is an individual timed event which forms a node of the trace tree. A single trace can contain spans from multiple services.

func NewClient

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient creates a new trace service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

Service for collecting and viewing traces and spans within a trace.

A trace is a collection of spans corresponding to a single operation or a set of operations in an application.

A span is an individual timed event which forms a node of the trace tree. A single trace can contain spans from multiple services.

Example
package main

import (
	"context"

	trace "cloud.google.com/go/trace/apiv2"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := trace.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}
Output:

func NewRESTClient added in v1.5.0

func NewRESTClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewRESTClient creates a new trace service rest client.

Service for collecting and viewing traces and spans within a trace.

A trace is a collection of spans corresponding to a single operation or a set of operations in an application.

A span is an individual timed event which forms a node of the trace tree. A single trace can contain spans from multiple services.

Example
package main

import (
	"context"

	trace "cloud.google.com/go/trace/apiv2"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := trace.NewRESTClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c

Output:

func (*Client) BatchWriteSpans

func (c *Client) BatchWriteSpans(ctx context.Context, req *tracepb.BatchWriteSpansRequest, opts ...gax.CallOption) error

BatchWriteSpans batch writes new spans to new or existing traces. You cannot update existing spans.

Example
package main

import (
	"context"

	trace "cloud.google.com/go/trace/apiv2"
	tracepb "cloud.google.com/go/trace/apiv2/tracepb"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := trace.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &tracepb.BatchWriteSpansRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/trace/apiv2/tracepb#BatchWriteSpansRequest.
	}
	err = c.BatchWriteSpans(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
}
Output:

func (*Client) Close

func (c *Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Client) Connection deprecated

func (c *Client) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated: Connections are now pooled so this method does not always return the same resource.

func (*Client) CreateSpan

func (c *Client) CreateSpan(ctx context.Context, req *tracepb.Span, opts ...gax.CallOption) (*tracepb.Span, error)

CreateSpan creates a new span.

Example
package main

import (
	"context"

	trace "cloud.google.com/go/trace/apiv2"
