var DefaultDurationToField = DurationToTimeMillisField

DefaultDurationToField is the default implementation of converting request duration to a Zap field.

Functions

func DefaultClientCodeToLevel

func DefaultClientCodeToLevel(code codes.Code) logger.Level

DefaultClientCodeToLevel is the default implementation of gRPC return codes to log levels for client side.

func DefaultCodeToLevel

func DefaultCodeToLevel(code codes.Code) logger.Level

DefaultCodeToLevel is the default implementation of gRPC return codes and interceptor log level for server side.

func DefaultMessageProducer

func DefaultMessageProducer(ctx context.Context, msg string, level logger.Level, code codes.Code, err error, duration ctxlog.Fields)

DefaultMessageProducer writes the default message

func DurationToDurationField

func DurationToDurationField(duration time.Duration) map[string]interface{}

DurationToDurationField uses a Duration field to log the request duration and leaves it up to Zap's encoder settings to determine how that is output.

func DurationToTimeMillisField

func DurationToTimeMillisField(duration time.Duration) ctxlog.Fields

DurationToTimeMillisField converts the duration to milliseconds and uses the key `grpc.time_ms`.

func StreamClientInterceptor

func StreamClientInterceptor(opts ...Option) grpc.StreamClientInterceptor

StreamClientInterceptor returns a new streaming client interceptor that optionally logs the execution of external gRPC calls.

func StreamServerInterceptor

func StreamServerInterceptor(opts ...Option) grpc.StreamServerInterceptor

StreamServerInterceptor returns a new streaming server interceptor that adds zap.Logger to the context.

func UnaryClientInterceptor

func UnaryClientInterceptor(opts ...Option) grpc.UnaryClientInterceptor

UnaryClientInterceptor returns a new unary client interceptor that optionally logs the execution of external gRPC calls.

func UnaryServerInterceptor

func UnaryServerInterceptor(opts ...Option) grpc.UnaryServerInterceptor

UnaryServerInterceptor returns a new unary server interceptors that adds zap.Logger to the context.

Types

type CodeToLevel
