Constants

const (
	DEBUG   = Severity("debug")
	INFO    = Severity("info")
	WARNING = Severity("warning")
	ERROR   = Severity("error")
	FATAL   = Severity("fatal")
)

Variables

var (
	ErrPacketDropped         = errors.New("raven: packet dropped")
	ErrUnableToUnmarshalJSON = errors.New("raven: unable to unmarshal JSON")
	ErrMissingUser           = errors.New("raven: dsn missing public key and/or password")
	ErrMissingProjectID      = errors.New("raven: dsn missing project id")
	ErrInvalidSampleRate     = errors.New("raven: sample rate should be between 0 and 1")
)
var DefaultClient = newClient(nil)

Initialize a default *Client instance

var MaxQueueBuffer = 100

The maximum number of packets that will be buffered waiting to be delivered. Packets will be dropped if the buffer is full. Used by NewClient.

func Capture

func Capture(packet *Packet, captureTags map[string]string) (eventID string, ch chan error)

Capture asynchronously delivers a packet to the Sentry server with the default *Client. It is a no-op when client is nil. A channel is provided if it is important to check for a send's success.

func CaptureError

func CaptureError(err error, tags map[string]string, interfaces ...Interface) string

CaptureErrors formats and delivers an error to the Sentry server using the default *Client. Adds a stacktrace to the packet, excluding the call to this method.

func CaptureErrorAndWait

func CaptureErrorAndWait(err error, tags map[string]string, interfaces ...Interface) string

CaptureErrorAndWait is identical to CaptureError, except it blocks and assures that the event was sent

func CaptureMessage

func CaptureMessage(message string, tags map[string]string, interfaces ...Interface) string

CaptureMessage formats and delivers a string message to the Sentry server with the default *Client

func CaptureMessageAndWait

func CapturePanic

func CapturePanic(f func(), tags map[string]string, interfaces ...Interface) (interface{}, string)

CapturePanic calls f and then recovers and reports a panic to the Sentry server if it occurs. If an error is captured, both the error and the reported Sentry error ID are returned.
