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

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 OpenCensus.

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.

CallOptions

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

CallOptions contains the retry settings for each method of Client.

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.

This file describes an API for collecting and viewing traces and spans within a trace. A Trace is a collection of spans corresponding to a single operation or set of operations for an application. A span is an individual timed event which forms a node of the trace tree. A single trace may contain span(s) 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.

Example

package main

import (
	trace "cloud.google.com/go/trace/apiv2"
	"context"
)

func main() {
	ctx := context.Background()
	c, err := trace.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

func (*Client) BatchWriteSpans

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

BatchWriteSpans sends new spans to new or existing traces. You cannot update existing spans.

Example

package main

import (
	trace "cloud.google.com/go/trace/apiv2"
	"context"
	cloudtracepb "google.golang.org/genproto/googleapis/devtools/cloudtrace/v2"
)

func main() {
	ctx := context.Background()
	c, err := trace.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &cloudtracepb.BatchWriteSpansRequest{
		// TODO: Fill request struct fields.
	}
	err = c.BatchWriteSpans(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
}

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

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

Connection returns a connection to the API service.

Deprecated.

func (*Client) CreateSpan

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

CreateSpan creates a new span.

Example

package main

import (
	trace "cloud.google.com/go/trace/apiv2"
	"context"
	cloudtracepb "google.golang.org/genproto/googleapis/devtools/cloudtrace/v2"
)

func main() {
	ctx := context.Background()
	c, err := trace.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &cloudtracepb.Span{
		// TODO: Fill request struct fields.
	}
	resp, err := c.CreateSpan(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
