Functions

func New

func New(ctx context.Context, opts ...Option) (*otlptrace.Exporter, error)

New constructs a new Exporter and starts it.

func NewClient

func NewClient(opts ...Option) otlptrace.Client

NewClient creates a new gRPC trace client.

func NewUnstarted

func NewUnstarted(opts ...Option) *otlptrace.Exporter

NewUnstarted constructs a new Exporter and does not start it.

Types

type Option

type Option interface {
	// contains filtered or unexported methods
}

Option applies an option to the gRPC driver.

func WithCompressor

func WithCompressor(compressor string) Option

WithCompressor sets the compressor for the gRPC client to use when sending requests. It is the responsibility of the caller to ensure that the compressor set has been registered with google.golang.org/grpc/encoding. This can be done by encoding.RegisterCompressor. Some compressors auto-register on import, such as gzip, which can be registered by calling `import _ "google.golang.org/grpc/encoding/gzip"`.

This option has no effect if WithGRPCConn is used.

func WithDialOption

func WithDialOption(opts ...grpc.DialOption) Option

WithDialOption sets explicit grpc.DialOptions to use when making a connection. The options here are appended to the internal grpc.DialOptions used so they will take precedence over any other internal grpc.DialOptions they might conflict with.

This option has no effect if WithGRPCConn is used.

func WithEndpoint

func WithEndpoint(endpoint string) Option

WithEndpoint sets the target endpoint the exporter will connect to. If unset, localhost:4317 will be used as a default.

This option has no effect if WithGRPCConn is used.

func WithGRPCConn added in v1.1.0

func WithGRPCConn(conn *grpc.ClientConn) Option

WithGRPCConn sets conn as the gRPC ClientConn used for all communication.

This option takes precedence over any other option that relates to establishing or persisting a gRPC connection to a target endpoint. Any other option of those types passed will be ignored.

It is the callers responsibility to close the passed conn. The client Shutdown method will not close this connection.

func WithHeaders

func WithHeaders(headers map[string]string) Option

WithHeaders will send the provided headers with each gRPC requests.

func WithInsecure

func WithInsecure() Option

WithInsecure disables client transport security for the exporter's gRPC connection just like grpc.WithInsecure() (https://pkg.go.dev/google.golang.org/grpc#WithInsecure) does. Note, by default, client security is required unless WithInsecure is used.

This option has no effect if WithGRPCConn is used.

func WithReconnectionPeriod

func WithReconnectionPeriod(rp time.Duration) Option

WithReconnectionPeriod set the minimum amount of time between connection attempts to the target endpoint.

This option has no effect if WithGRPCConn is used.

func WithRetry

func WithRetry(settings RetryConfig) Option

WithRetry sets the retry policy for transient retryable errors that may be returned by the target endpoint when exporting a batch of spans.

If the target endpoint responds with not only a retryable error, but explicitly returns a backoff time in the response. That time will take precedence over these settings.

These settings do not define any network retry strategy. That is entirely handled by the gRPC ClientConn.

If unset, the default retry policy will be used. It will retry the export 5 seconds after receiving a retryable error and increase exponentially after each error for no more than a total time of 1 minute.

func WithServiceConfig

func WithServiceConfig(serviceConfig string) Option

WithServiceConfig defines the default gRPC service config used.

This option has no effect if WithGRPCConn is used.

func WithTLSCredentials

func WithTLSCredentials(creds credentials.TransportCredentials) Option

WithTLSCredentials allows the connection to use TLS credentials when talking to the server. It takes in grpc.TransportCredentials instead of say a Certificate file or a tls.Certificate, because the retrieving of these credentials can be done in many ways e.g. plain file, in code tls.Config or by certificate rotation, so it is up to the caller to decide what to use.

This option has no effect if WithGRPCConn is used.

func WithTimeout

func WithTimeout(duration time.Duration) Option

WithTimeout sets the max amount of time a client will attempt to export a batch of spans. This takes precedence over any retry settings defined with WithRetry, once this time limit has been reached the export is abandoned and the batch of spans is dropped.

If unset, the default timeout will be set to 10 seconds.

type RetryConfig

type RetryConfig retry.Config

RetryConfig defines configuration for retrying export of span batches that failed to be received by the target endpoint.

This configuration does not define any network retry strategy. That is entirely handled by the gRPC ClientConn.
