Sentry

Official Sentry SDK for Go

Build Status Go Report Card Discord GoDoc go.dev

sentry-go provides a Sentry client implementation for the Go programming language. This is the next generation of the Go SDK for Sentry, intended to replace the raven-go package.

Looking for the old raven-go SDK documentation? See the Legacy client section here. If you want to start using sentry-go instead, check out the migration guide.

Requirements

The only requirement is a Go compiler.

We verify this package against the 3 most recent releases of Go. Those are the supported versions. The exact versions are defined in GitHub workflow.

In addition, we run tests against the current master branch of the Go toolchain, though support for this configuration is best-effort.

Installation

sentry-go can be installed like any other Go library through go get:

$ go get github.com/getsentry/sentry-go@latest

Check out the list of released versions.

Configuration

To use sentry-go, you’ll need to import the sentry-go package and initialize it with your DSN and other options.

If not specified in the SDK initialization, the DSN, Release and Environment are read from the environment variables SENTRY_DSN, SENTRY_RELEASE and SENTRY_ENVIRONMENT, respectively.

More on this in the Configuration section of the official Sentry Go SDK documentation.

Usage

The SDK supports reporting errors and tracking application performance.

To get started, have a look at one of our examples:

We also provide a complete API reference.

Overview

Package repository: https://github.com/getsentry/sentry-go/

For more information about Sentry and SDK features, please have a look at the official documentation site: https://docs.sentry.io/platforms/go/

Example (TransportWithHooks)

Initializing the SDK with a custom HTTP transport gives a lot of flexibility to inspect requests and responses. This example adds before and after hooks. 

package main

import (
	"fmt"
	"net/http"
	"net/http/httputil"
	"os"
	"time"

	"github.com/getsentry/sentry-go"
)

// TransportWithHooks is an http.RoundTripper that wraps an existing
// http.RoundTripper adding hooks that run before and after each round trip.
type TransportWithHooks struct {
	http.RoundTripper
	Before func(*http.Request) error
	After  func(*http.Request, *http.Response, error) (*http.Response, error)
}

func (t *TransportWithHooks) RoundTrip(req *http.Request) (*http.Response, error) {
	if err := t.Before(req); err != nil {
		return nil, err
	}
	resp, err := t.RoundTripper.RoundTrip(req)
	return t.After(req, resp, err)
}

// Initializing the SDK with a custom HTTP transport gives a lot of flexibility
// to inspect requests and responses. This example adds before and after hooks.
func main() {
	err := sentry.Init(sentry.ClientOptions{
		// Either set your DSN here or set the SENTRY_DSN environment variable.
		Dsn:   "",
		Debug: true,
		HTTPTransport: &TransportWithHooks{
			RoundTripper: http.DefaultTransport,
			Before: func(req *http.Request) error {
				if b, err := httputil.DumpRequestOut(req, true); err != nil {
					fmt.Println(err)
				} else {
					fmt.Printf("%s\n", b)
				}
				return nil
			},
			After: func(req *http.Request, resp *http.Response, err error) (*http.Response, error) {
				if b, err := httputil.DumpResponse(resp, true); err != nil {
					fmt.Println(err)
				} else {
					fmt.Printf("%s\n", b)
				}
				return resp, err
			},
		},
	})
	if err != nil {
		fmt.Fprintf(os.Stderr, "sentry.Init: %s\n", err)
		os.Exit(1)
	}
	defer sentry.Flush(2 * time.Second)

	sentry.CaptureMessage("test")
}

Variables

View Source 
var Logger = log.New(io.Discard, "[Sentry] ", log.LstdFlags)

Logger is an instance of log.Logger that is use to provide debug information about running Sentry Client can be enabled by either using Logger.SetOutput directly or with Debug client option.

Functions

func AddBreadcrumb 

func AddBreadcrumb(breadcrumb *Breadcrumb)

AddBreadcrumb records a new breadcrumb.

The total number of breadcrumbs that can be recorded are limited by the configuration on the client.

func AddGlobalEventProcessor 

func AddGlobalEventProcessor(processor EventProcessor)

AddGlobalEventProcessor adds processor to the global list of event processors. Global event processors apply to all events.

AddGlobalEventProcessor is deprecated. Most users will prefer to initialize the SDK with Init and provide a ClientOptions.BeforeSend function or use Scope.AddEventProcessor instead.

func ConfigureScope 

func ConfigureScope(f func(scope *Scope))

ConfigureScope is a shorthand for CurrentHub().ConfigureScope.

func Flush 

func Flush(timeout time.Duration) bool

Flush waits until the underlying Transport sends any buffered events to the Sentry server, blocking for at most the given timeout. It returns false if the timeout was reached. In that case, some events may not have been sent.

Flush should be called before terminating the program to avoid unintentionally dropping events.

Do not call Flush indiscriminately after every call to CaptureEvent, CaptureException or CaptureMessage. Instead, to have the SDK send events over the network synchronously, configure it to use the HTTPSyncTransport in the call to Init.

func HasHubOnContext 

func HasHubOnContext(ctx context.Context) bool

HasHubOnContext checks whether Hub instance is bound to a given Context struct.

func Init 

func Init(options ClientOptions) error

Init initializes the SDK with options. The returned error is non-nil if options is invalid, for instance if a malformed DSN is provided.

func PopScope 

func PopScope()

PopScope is a shorthand for CurrentHub().PopScope.

func PushScope 

func PushScope()

PushScope is a shorthand for CurrentHub().PushScope.

func SetHubOnContext 

func SetHubOnContext(ctx context.Context, hub *Hub) context.Context

SetHubOnContext stores given Hub instance on the Context struct and returns a new Context.

func WithScope 

func WithScope(f func(scope *Scope))

WithScope is a shorthand for CurrentHub().WithScope.

Types

type Attachment added in v0.23.0 

type Attachment struct {
	Filename    string
	ContentType string
	Payload     []byte
}

Attachment allows associating files with your events to aid in investigation. An event may contain one or more attachments. 

type Breadcrumb struct {
	Type      string                 `json:"type,omitempty"`
	Category  string                 `json:"category,omitempty"`
	Message   string                 `json:"message,omitempty"`
	Data      map[string]interface{} `json:"data,omitempty"`
	Level     Level                  `json:"level,omitempty"`
	Timestamp time.Time              `json:"timestamp"`
}

Breadcrumb specifies an application event that occurred before a Sentry event. An event may contain one or more breadcrumbs. 

func (b *Breadcrumb) MarshalJSON() ([]byte, error)

MarshalJSON converts the Breadcrumb struct to JSON. 

type BreadcrumbHint map[string]interface{}

BreadcrumbHint contains information that can be associated with a Breadcrumb.

type CheckIn added in v0.23.0 

type CheckIn struct {
	// Check-In ID (unique and client generated)
	ID EventID `json:"check_in_id"`
	// The distinct slug of the monitor.
	MonitorSlug string `json:"monitor_slug"`
	// The status of the check-in.
	Status CheckInStatus `json:"status"`
	// The duration of the check-in. Will only take effect if the status is ok or error.
	Duration time.Duration `json:"duration,omitempty"`
}

type CheckInStatus added in v0.23.0 

type CheckInStatus string
const (
	CheckInStatusInProgress CheckInStatus = "in_progress"
	CheckInStatusOK         CheckInStatus = "ok"
	CheckInStatusError      CheckInStatus = "error"
)

type Client 

type Client struct {

	// Transport is read-only. Replacing the transport of an existing client is
	// not supported, create a new client instead.
	Transport Transport
	// contains filtered or unexported fields
}

Client is the underlying processor that is used by the main API and Hub instances. It must be created with NewClient.

func NewClient 

func NewClient(options ClientOptions) (*Client, error)

NewClient creates and returns an instance of Client configured using ClientOptions.

Most users will not create clients directly. Instead, initialize the SDK with Init and use the package-level functions (for simple programs that run on a single goroutine) or hub methods (for concurrent programs, for example web servers).

func (*Client) AddEventProcessor 

func (client *Client) AddEventProcessor(processor EventProcessor)

AddEventProcessor adds an event processor to the client. It must not be called from concurrent goroutines. Most users will prefer to use ClientOptions.BeforeSend or Scope.AddEventProcessor instead.

Note that typical programs have only a single client created by Init and the client is shared among multiple hubs, one per goroutine, such that adding an event processor to the client affects all hubs that share the client.

func (*Client) CaptureCheckIn added in v0.23.0 

func (client *Client) CaptureCheckIn(checkIn *CheckIn, monitorConfig *MonitorConfig, scope EventModifier) *EventID

CaptureCheckIn captures a check in.

func (*Client) CaptureEvent 

func (client *Client) CaptureEvent(event *Event, hint *EventHint, scope EventModifier) *EventID

CaptureEvent captures an event on the currently active client if any.

The event must already be assembled. Typically code would instead use the utility methods like CaptureException. The return value is the event ID. In case Sentry is disabled or event was dropped, the return value will be nil.

func (*Client) CaptureException 

func (client *Client) CaptureException(exception error, hint *EventHint, scope EventModifier) *EventID

CaptureException captures an error.

func (*Client) CaptureMessage 

func (client *Client) CaptureMessage(message string, hint *EventHint, scope EventModifier) *EventID

CaptureMessage captures an arbitrary message.

func (*Client) EventFromCheckIn added in v0.23.0 

func (client *Client) EventFromCheckIn(checkIn *CheckIn, monitorConfig *MonitorConfig) *Event

EventFromCheckIn creates a new Sentry event from the given `check_in` instance.

func (*Client) EventFromException added in v0.21.0 

func (client *Client) EventFromException(exception error, level Level) *Event

EventFromException creates a new Sentry event from the given `error` instance.

func (*Client) EventFromMessage added in v0.21.0 

func (client *Client) EventFromMessage(message string, level Level) *Event

EventFromMessage creates an event from the given message string.

func (*Client) Flush 

func (client *Client) Flush(timeout time.Duration) bool

Flush waits until the underlying Transport sends any buffered events to the Sentry server, blocking for at most the given timeout. It returns false if the timeout was reached. In that case, some events may not have been sent.

Flush should be called before terminating the program to avoid unintentionally dropping events.

Do not call Flush indiscriminately after every call to CaptureEvent, CaptureException or CaptureMessage. Instead, to have the SDK send events over the network synchronously, configure it to use the HTTPSyncTransport in the call to Init.

func (*Client) GetSDKIdentifier added in v0.24.0 

func (client *Client) GetSDKIdentifier() string

func (*Client) Options 

func (client *Client) Options() ClientOptions

Options return ClientOptions for the current Client.

func (*Client) Recover 

func (client *Client) Recover(err interface{}, hint *EventHint, scope EventModifier) *EventID

Recover captures a panic. Returns EventID if successfully, or nil if there's no error to recover from.

func (*Client) RecoverWithContext 

func (client *Client) RecoverWithContext(
	ctx context.Context,
	err interface{},
	hint *EventHint,
	scope EventModifier,
) *EventID

RecoverWithContext captures a panic and passes relevant context object. Returns EventID if successfully, or nil if there's no error to recover from.

func (*Client) SetSDKIdentifier added in v0.24.0 

func (client *Client) SetSDKIdentifier(identifier string)

	// The DSN to use. If the DSN is not set, the client is effectively
	// disabled.
	Dsn string
	// In debug mode, the debug information is printed to stdout to help you
	// understand what sentry is doing.
	Debug bool
	// Configures whether SDK should generate and attach stacktraces to pure
	// capture message calls.
	AttachStacktrace bool
	// The sample rate for event submission in the range [0.0, 1.0]. By default,
	// all events are sent. Thus, as a historical special case, the sample rate

	// empty string.
	SampleRate float64
	// Enable performance tracing.
	EnableTracing bool
	// The sample rate for sampling traces in the range [0.0, 1.0].

	// name.  If a match is found, then the transaction  will be dropped.
	IgnoreTransactions []string
	// If this flag is enabled, certain personally identifiable information (PII) is added by active integrations.
	// By default, no such data is sent.
	SendDefaultPII bool
	// BeforeSend is called before error events are sent to Sentry.
	// Use it to mutate the event or return nil to discard the event.
	BeforeSend func(event *Event, hint *EventHint) *Event
	// BeforeSendTransaction is called before transaction events are sent to Sentry.
	// Use it to mutate the transaction or return nil to discard the transaction.
	BeforeSendTransaction func(event *Event, hint *EventHint) *Event
	// Before breadcrumb add callback.
	BeforeBreadcrumb func(breadcrumb *Breadcrumb, hint *BreadcrumbHint) *Breadcrumb
	// Integrations to be installed on the current Client, receives default
	// integrations.

	// The transport to use. Defaults to HTTPTransport.
	Transport Transport
	// The server name to be reported.
	ServerName string
	// The release to be sent with events.
	//
	// Some Sentry features are built around releases, and, thus, reporting
	// events with a non-empty release improves the product experience. See
	// https://docs.sentry.io/product/releases/.
	//
	// If Release is not set, the SDK will try to derive a default value
	// from environment variables or the Git repository in the working
	// directory.
	//
	// If you distribute a compiled binary, it is recommended to set the
	// Release value explicitly at build time. As an example, you can use:
	//
	// 	go build -ldflags='-X main.release=VALUE'
	//
	// That will set the value of a predeclared variable 'release' in the
	// 'main' package to 'VALUE'. Then, use that variable when initializing
	// the SDK:
	//
	// 	sentry.Init(ClientOptions{Release: release})
	//
	// See https://golang.org/cmd/go/ and https://golang.org/cmd/link/ for
	// the official documentation of -ldflags and -X, respectively.
	Release string
	// The dist to be sent with events.
	Dist string
	// The environment to be sent with events.
	Environment string
	// Maximum number of breadcrumbs
	// when MaxBreadcrumbs is negative then ignore breadcrumbs.
	MaxBreadcrumbs int
	// Maximum number of spans.
	//
	// See https://develop.sentry.dev/sdk/envelopes/#size-limits for size limits
	// applied during event ingestion. Events that exceed these limits might get dropped.
	MaxSpans int
	// An optional pointer to http.Client that will be used with a default
	// HTTPTransport. Using your own client will make HTTPTransport, HTTPProxy,
	// HTTPSProxy and CaCerts options ignored.
	HTTPClient *http.Client

	// HTTPTransport. Using your own transport will make HTTPProxy, HTTPSProxy
	// and CaCerts options ignored.
	HTTPTransport http.RoundTripper
	// An optional HTTP proxy to use.
	// This will default to the HTTP_PROXY environment variable.
	HTTPProxy string
	// An optional HTTPS proxy to use.
	// This will default to the HTTPS_PROXY environment variable.
	// HTTPS_PROXY takes precedence over HTTP_PROXY for https requests.
	HTTPSProxy string
	// An optional set of SSL certificates to use.
	CaCerts *x509.CertPool
	// MaxErrorDepth is the maximum number of errors reported in a chain of errors.
	// This protects the SDK from an arbitrarily long chain of wrapped errors.
	//
	// An additional consideration is that arguably reporting a long chain of errors
	// is of little use when debugging production errors with Sentry. The Sentry UI
	// is not optimized for long chains either. The top-level error together with a
	// stack trace is often the most useful information.

type HTTPSyncTransport 

type HTTPSyncTransport struct {

	// HTTP Client request timeout. Defaults to 30 seconds.
	Timeout time.Duration
	// contains filtered or unexported fields
}

HTTPSyncTransport is a blocking implementation of Transport.

Clients using this transport will send requests to Sentry sequentially and block until a response is returned.

The blocking behavior is useful in a limited set of use cases. For example, use it when deploying code to a Function as a Service ("Serverless") platform, where any work happening in a background goroutine is not guaranteed to execute.

For most cases, prefer HTTPTransport.

func NewHTTPSyncTransport 

func NewHTTPSyncTransport() *HTTPSyncTransport

NewHTTPSyncTransport returns a new pre-configured instance of HTTPSyncTransport.

func (*HTTPSyncTransport) Configure 

func (t *HTTPSyncTransport) Configure(options ClientOptions)

Configure is called by the Client itself, providing it it's own ClientOptions.

func (*HTTPSyncTransport) Flush 

func (t *HTTPSyncTransport) Flush(_ time.Duration) bool

Flush is a no-op for HTTPSyncTransport. It always returns true immediately.

func (*HTTPSyncTransport) SendEvent 

func (t *HTTPSyncTransport) SendEvent(event *Event)

SendEvent assembles a new packet out of Event and sends it to remote server.

type HTTPTransport 

type HTTPTransport struct {

	// Size of the transport buffer. Defaults to 30.
	BufferSize int
	// HTTP Client request timeout. Defaults to 30 seconds.
	Timeout time.Duration
	// contains filtered or unexported fields
}

HTTPTransport is the default, non-blocking, implementation of Transport.

Clients using this transport will enqueue requests in a buffer and return to the caller before any network communication has happened. Requests are sent to Sentry sequentially from a background goroutine.

func NewHTTPTransport 

func NewHTTPTransport() *HTTPTransport

NewHTTPTransport returns a new pre-configured instance of HTTPTransport.

func (*HTTPTransport) Configure 

func (t *HTTPTransport) Configure(options ClientOptions)

func (*HTTPTransport) Flush 

func (t *HTTPTransport) Flush(timeout time.Duration) bool

Flush waits until any buffered events are sent to the Sentry server, blocking for at most the given timeout. It returns false if the timeout was reached. In that case, some events may not have been sent.

Flush should be called before terminating the program to avoid unintentionally dropping events.

Do not call Flush indiscriminately after every call to SendEvent. Instead, to have the SDK send events over the network synchronously, configure it to use the HTTPSyncTransport in the call to Init.

func (*HTTPTransport) SendEvent 

func (t *HTTPTransport) SendEvent(event *Event)

SendEvent assembles a new packet out of Event and sends it to remote server.

type Hub 

type Hub struct {
	// contains filtered or unexported fields
}

Hub is the central object that manages scopes and clients.

This can be used to capture events and manage the scope. The default hub that is available automatically.

In most situations developers do not need to interface the hub. Instead toplevel convenience functions are exposed that will automatically dispatch to global (CurrentHub) hub. In some situations this might not be possible in which case it might become necessary to manually work with the hub. This is for instance the case when working with async code.

func CurrentHub 

func CurrentHub() *Hub

CurrentHub returns an instance of previously initialized Hub stored in the global namespace.

func GetHubFromContext 

func GetHubFromContext(ctx context.Context) *Hub

GetHubFromContext tries to retrieve Hub instance from the given Context struct or return nil if one is not found.

It is useful to set data that applies to all events that share the current scope.

Modifying the scope affects all references to the current scope.

See also WithScope for making isolated temporary changes.

func (*Hub) Flush 

func (hub *Hub) Flush(timeout time.Duration) bool

Flush waits until the underlying Transport sends any buffered events to the Sentry server, blocking for at most the given timeout. It returns false if the timeout was reached. In that case, some events may not have been sent.

Flush should be called before terminating the program to avoid unintentionally dropping events.

Do not call Flush indiscriminately after every call to CaptureEvent, CaptureException or CaptureMessage. Instead, to have the SDK send events over the network synchronously, configure it to use the HTTPSyncTransport in the call to Init.

func (*Hub) LastEventID 

func (hub *Hub) LastEventID() EventID

LastEventID returns the ID of the last event (error or message) captured through the hub and sent to the underlying transport.

Transactions and events dropped by sampling or event processors do not change the last event ID.

LastEventID is a convenience method to cover use cases in which errors are captured indirectly and the ID is needed. For example, it can be used as part of an HTTP middleware to log the ID of the last error, if any.

For more flexibility, consider instead using the ClientOptions.BeforeSend function or event processors.

func (*Hub) PopScope 

func (hub *Hub) PopScope()

PopScope drops the most recent scope.

Calls to PopScope must be coordinated with PushScope. For most cases, using WithScope should be more convenient.

Calls to PopScope that do not match previous calls to PushScope are silently ignored.

func (*Hub) RecoverWithContext 

func (hub *Hub) RecoverWithContext(ctx context.Context, err interface{}) *EventID

RecoverWithContext calls the method of a same name on currently bound Client instance passing it a top-level Scope. Returns EventID if successfully, or nil if there's no Scope or Client available.

func (*Hub) Scope 

func (hub *Hub) Scope() *Scope

Scope returns top-level Scope of the current Hub or nil if no Scope is bound.

func (*Hub) WithScope 

func (hub *Hub) WithScope(f func(scope *Scope))

WithScope runs f in an isolated temporary scope.

It is useful when extra data should be sent with a single capture call, for instance a different level or tags.

The scope passed to f starts as a clone of the current scope and can be freely modified without affecting the current scope.

It is a shorthand for PushScope followed by PopScope.

TODO(tracing): possibly expand SamplingContext to include custom / user-provided data.

type Scope 

type Scope struct {
	// contains filtered or unexported fields
}

Scope holds contextual data for the current scope.

The scope is an object that can cloned efficiently and stores data that is locally relevant to an event. For instance the scope will hold recorded breadcrumbs and similar information.

The scope can be interacted with in two ways. First, the scope is routinely updated with information by functions such as AddBreadcrumb which will modify the current scope. Second, the current scope can be configured through the ConfigureScope function or Hub method of the same name.

The scope is meant to be modified but not inspected directly. When preparing an event for reporting, the current client adds information from the current scope into the event.

	// contains filtered or unexported fields
}

A Span is the building block of a Sentry transaction. Spans build up a tree structure of timed operations. The span tree makes up a transaction event that is sent to Sentry when the root span is finished.

Spans must be started with either StartSpan or Span.StartChild.

func SpanFromContext added in v0.23.0 

func SpanFromContext(ctx context.Context) *Span

SpanFromContext returns the last span stored in the context, or nil if no span is set on the context.

func StartSpan added in v0.9.0 

func StartSpan(ctx context.Context, operation string, options ...SpanOption) *Span

StartSpan starts a new span to describe an operation. The new span will be a child of the last span stored in ctx, if any.

One or more options can be used to modify the span properties. Typically one option as a function literal is enough. Combining multiple options can be useful to define and reuse specific properties with named functions.

Caller should call the Finish method on the span to mark its end. Finishing a root span sends the span and all of its children, recursively, as a transaction to Sentry.

func StartTransaction added in v0.15.0 

func StartTransaction(ctx context.Context, name string, options ...SpanOption) *Span

StartTransaction will create a transaction (root span) if there's no existing transaction in the context otherwise, it will return the existing transaction.

func TransactionFromContext added in v0.9.0 

func TransactionFromContext(ctx context.Context) *Span

TransactionFromContext returns the root span of the current transaction. It returns nil if no transaction is tracked in the context.

func (*Span) Context added in v0.9.0 

func (s *Span) Context() context.Context

Context returns the context containing the span.

func (*Span) Finish added in v0.9.0 

func (s *Span) Finish()

Finish sets the span's end time, unless already set. If the span is the root of a span tree, Finish sends the span tree to Sentry as a transaction.

The logic is executed at most once per span, so that (incorrectly) calling it twice never double sends to Sentry.

func (*Span) GetTransaction added in v0.18.0 

func (s *Span) GetTransaction() *Span

GetTransaction returns the transaction that contains this span.

For transaction spans it returns itself. For spans that were created manually the method returns "nil".

func (*Span) SetData added in v0.18.0 

func (s *Span) SetData(name, value string)

SetData sets a data on the span. It is recommended to use SetData instead of accessing the data map directly as SetData takes care of initializing the map when necessary.

StartChild starts a new child span.

The call span.StartChild(operation, options...) is a shortcut for StartSpan(span.Context(), operation, options...).

func (*Span) ToBaggage added in v0.16.0 

func (s *Span) ToBaggage() string

ToBaggage returns the serialized DynamicSamplingContext from a transaction. Use this function to propagate the DynamicSamplingContext to a downstream SDK, either as the value of the "baggage" HTTP header, or as an html "baggage" meta tag.

func (*Span) ToSentryTrace added in v0.9.0 

func (s *Span) ToSentryTrace() string

ToSentryTrace returns the seralized TraceParentContext from a transaction/span. Use this function to propagate the TraceParentContext to a downstream SDK, either as the value of the "sentry-trace" HTTP header, or as an html "sentry-trace" meta tag.

func WithSpanSampled added in v0.21.0 

func WithSpanSampled(sampled Sampled) SpanOption

WithSpanSampled updates the sampling flag for a given span.

func WithTransactionName added in v0.21.0 

func WithTransactionName(name string) SpanOption

WithTransactionName option sets the name of the current transaction.

A span tree has a single transaction name, therefore using this option when starting a span affects the span tree as a whole, potentially overwriting a name set previously.

func WithTransactionSource added in v0.21.0 

func WithTransactionSource(source TransactionSource) SpanOption

WithTransactionSource sets the source of the transaction name.

Note: if the transaction source is not a valid source (as described by the spec https://develop.sentry.dev/sdk/event-payloads/transaction/#transaction-annotations), it will be corrected to "custom" eventually, before the transaction is sent.

	Name       string      `json:"name,omitempty"`
	Stacktrace *Stacktrace `json:"stacktrace,omitempty"`
	Crashed    bool        `json:"crashed,omitempty"`
	Current    bool        `json:"current,omitempty"`
}

Thread specifies threads that were running at the time of an event.

type TraceContext added in v0.7.0 

type TraceContext struct {
	TraceID      TraceID    `json:"trace_id"`
	SpanID       SpanID     `json:"span_id"`
	ParentSpanID SpanID     `json:"parent_span_id"`
	Op           string     `json:"op,omitempty"`
	Description  string     `json:"description,omitempty"`
	Status       SpanStatus `json:"status,omitempty"`
}

A TraceContext carries information about an ongoing trace and is meant to be stored in Event.Contexts (as *TraceContext).

func (TraceContext) Map added in v0.14.0 

func (tc TraceContext) Map() map[string]interface{}

func (*TraceContext) MarshalJSON added in v0.9.0 

func (tc *TraceContext) MarshalJSON() ([]byte, error)

type TraceID added in v0.9.0 

type TraceID [16]byte

TraceID identifies a trace.

func (TraceID) Hex added in v0.9.0 

func (id TraceID) Hex() []byte

func (TraceID) MarshalText added in v0.9.0 

func (id TraceID) MarshalText() ([]byte, error)

func (TraceID) String added in v0.9.0

type TraceParentContext added in v0.18.0 

type TraceParentContext struct {
	TraceID      TraceID
	ParentSpanID SpanID
	Sampled      Sampled
}

TraceParentContext describes the context of a (remote) parent span.

The context is normally extracted from a received "sentry-trace" header and used to initialize a new transaction.

Note: the name might be not the best one. It was taken mostly to stay aligned with other SDKs, and it alludes to W3C "traceparent" header (https://www.w3.org/TR/trace-context/), which serves a similar purpose to "sentry-trace". We should eventually consider making this type internal-only and give it a better name.

func ParseTraceParentContext added in v0.18.0 

func ParseTraceParentContext(header []byte) (traceParentContext TraceParentContext, valid bool)

ParseTraceParentContext parses a sentry-trace header and builds a TraceParentContext from the parsed values. If the header was parsed correctly, the second returned argument ("valid") will be set to true, otherwise (e.g., empty or malformed header) it will be false.

type TracesSampler added in v0.9.0 

type TracesSampler func(ctx SamplingContext) float64

The TracesSample type is an adapter to allow the use of ordinary functions as a TracesSampler.

func (TracesSampler) Sample added in v0.9.0 

func (f TracesSampler) Sample(ctx SamplingContext) float64

	SourceCustom    TransactionSource = "custom"
	SourceURL       TransactionSource = "url"
	SourceRoute     TransactionSource = "route"
	SourceView      TransactionSource = "view"
	SourceComponent TransactionSource = "component"
	SourceTask      TransactionSource = "task"
)

type Transport 

type Transport interface {
	Flush(timeout time.Duration) bool
	Configure(options ClientOptions)
	SendEvent(event *Event)
}

Transport is used by the Client to deliver events to remote server.
