Overview

Package sentry is the official Sentry SDK for Go.

It has been cleaned up and modified by the Blend team to eliminate module issues.

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/blend/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")

}

Constants

	// HubContextKey is the key used to store the current Hub.
	HubContextKey = contextKey(1)
	// RequestContextKey is the key used to store the current http.Request.
	RequestContextKey = contextKey(2)
)

Keys used to store values in a Context. Use with Context.Value to access values stored by the SDK.

const Version = "0.8.0"

Version is the version of the SDK.

Variables

View Source 
var Logger = log.New(ioutil.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 deprecated 

func AddGlobalEventProcessor(processor EventProcessor)

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

Deprecated: Use Scope.AddEventProcessor or Client.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.

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.

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.

	Name() string
	SetupOnce(client *Client)
}

NewRequest avoids operations that depend on network access. In particular, it does not read r.Body.

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.
