Stackdriver Trace API v1 - Package cloud.google.com/go/trace/apiv1 (v0.81.0)

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.

For information about setting deadlines, reusing contexts, and more please visit pkg.go.dev/cloud.google.com/go.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

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

CallOptions

type CallOptions struct {
	ListTraces  []gax.CallOption
	GetTrace    []gax.CallOption
	PatchTraces []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.

func NewClient

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

NewClient creates a new trace service client.

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. Spans for a single trace may span multiple services.

Example

package main

import (
	"context"

	trace "cloud.google.com/go/trace/apiv1"
)

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

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) GetTrace

func (c *Client) GetTrace(ctx context.Context, req *cloudtracepb.GetTraceRequest, opts ...gax.CallOption) (*cloudtracepb.Trace, error)

GetTrace gets a single trace by its ID.

Example

package main

import (
	"context"

	trace "cloud.google.com/go/trace/apiv1"

	cloudtracepb "google.golang.org/genproto/googleapis/devtools/cloudtrace/v1"
)

func main() {
	// import cloudtracepb "google.golang.org/genproto/googleapis/devtools/cloudtrace/v1"

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

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

func (*Client) ListTraces

func (c *Client) ListTraces(ctx context.Context, req *cloudtracepb.ListTracesRequest, opts ...gax.CallOption) *TraceIterator

ListTraces returns of a list of traces that match the specified filter conditions.

Example

package main

import (
	"context"

	trace "cloud.google.com/go/trace/apiv1"
	"google.golang.org/api/iterator"

	cloudtracepb "google.golang.org/genproto/googleapis/devtools/cloudtrace/v1"
)

func main() {
	// import cloudtracepb "google.golang.org/genproto/googleapis/devtools/cloudtrace/v1"
	// import "google.golang.org/api/iterator"

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

	req := &cloudtracepb.ListTracesRequest{
		// TODO: Fill request struct fields.
	}
	it := c.ListTraces(ctx, req)
	for {
		resp, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			// TODO: Handle error.
		}
		// TODO: Use resp.
		_ = resp
	}
}

func (*Client) PatchTraces

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

PatchTraces sends new traces to Stackdriver Trace or updates existing traces. If the ID of a trace that you send matches that of an existing trace, any fields in the existing trace and its spans are overwritten by the provided values, and any new fields provided are merged with the existing trace data. If the ID does not match, a new trace is created.

Example

package main

import (
	"context"

	trace "cloud.google.com/go/trace/apiv1"

	cloudtracepb "google.golang.org/genproto/googleapis/devtools/cloudtrace/v1"
)

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

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

func (*Client) SetGoogleClientInfo

func (c *Client) SetGoogleClientInfo(keyval string)

SetGoogleClientInfo sets the name and version of the application in the x-goog-api-client header passed on each request. Also passes any provided key-value pairs. Intended for use by Google-written clients.

Internal use only.

TraceIterator

type TraceIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// InternalFetch is for use by the Google Cloud Libraries only.
	// It is not part of the stable interface of this package.
	//
	// InternalFetch returns results from a single call to the underlying RPC.
	// The number of results is no greater than pageSize.
	// If there are no more results, nextPageToken is empty and err is nil.
	InternalFetch func(pageSize int, pageToken string) (results []*cloudtracepb.Trace, nextPageToken string, err error)
	// contains filtered or unexported fields
}

TraceIterator manages a stream of *cloudtracepb.Trace.

func (*TraceIterator) Next

func (it *TraceIterator) Next() (*cloudtracepb.Trace, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*TraceIterator) PageInfo

func (it *TraceIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.
