Overview ¶
Package grpc is a generated protocol buffer package.
It is generated from these files:
fixtures_test.proto
It has these top-level messages:
FixtureRequest FixtureReply
Package grpc provides functions to trace the google.golang.org/grpc package v1.2.
Example (Client) ¶
package main
import (
"log"
grpctrace "github.com/gihyunk/dd-trace-go/contrib/google.golang.org/grpc"
"google.golang.org/grpc"
)
func main() {
// Create the client interceptor using the grpc trace package.
si := grpctrace.StreamClientInterceptor(grpctrace.WithServiceName("my-grpc-client"))
ui := grpctrace.UnaryClientInterceptor(grpctrace.WithServiceName("my-grpc-client"))
// Dial in using the created interceptor...
conn, err := grpc.Dial("localhost:50051", grpc.WithInsecure(),
grpc.WithStreamInterceptor(si), grpc.WithUnaryInterceptor(ui))
if err != nil {
log.Fatal(err)
}
defer conn.Close()
// And continue using the connection as normal.
}
Output:
Example (Server) ¶
package main
import (
"log"
"net"
grpctrace "github.com/gihyunk/dd-trace-go/contrib/google.golang.org/grpc"
"google.golang.org/grpc"
)
func main() {
// Create a listener for the server.
ln, err := net.Listen("tcp", ":50051")
if err != nil {
log.Fatal(err)
}
// Create the server interceptor using the grpc trace package.
si := grpctrace.StreamServerInterceptor(grpctrace.WithServiceName("my-grpc-client"))
ui := grpctrace.UnaryServerInterceptor(grpctrace.WithServiceName("my-grpc-client"))
// Initialize the grpc server as normal, using the tracing interceptor.
s := grpc.NewServer(grpc.StreamInterceptor(si), grpc.UnaryInterceptor(ui))
// ... register your services
// Start serving incoming connections.
if err := s.Serve(ln); err != nil {
log.Fatalf("failed to serve: %v", err)
}
}

Functions ¶
func NewClientStatsHandler ¶
NewClientStatsHandler returns a gRPC client stats.Handler to trace RPC calls.
func NewServerStatsHandler ¶
NewServerStatsHandler returns a gRPC server stats.Handler to trace RPC calls.
func RegisterFixtureServer ¶
func RegisterFixtureServer(s *grpc1.Server, srv FixtureServer)
func StreamClientInterceptor ¶
func StreamClientInterceptor(opts ...Option) grpc.StreamClientInterceptor
StreamClientInterceptor returns a grpc.StreamClientInterceptor which will trace client streams using the given set of options.
func StreamServerInterceptor ¶
func StreamServerInterceptor(opts ...Option) grpc.StreamServerInterceptor
StreamServerInterceptor will trace streaming requests to the given gRPC server.
func UnaryClientInterceptor ¶
func UnaryClientInterceptor(opts ...Option) grpc.UnaryClientInterceptor
UnaryClientInterceptor returns a grpc.UnaryClientInterceptor which will trace requests using the given set of options.
func UnaryServerInterceptor ¶
func UnaryServerInterceptor(opts ...Option) grpc.UnaryServerInterceptor
UnaryServerInterceptor will trace requests to the given grpc server.
Types ¶
type FixtureClient ¶
type FixtureClient interface {
Ping(ctx context.Context, in *FixtureRequest, opts ...grpc1.CallOption) (*FixtureReply, error)
StreamPing(ctx context.Context, opts ...grpc1.CallOption) (Fixture_StreamPingClient, error)
}
func NewFixtureClient ¶
func NewFixtureClient(cc *grpc1.ClientConn) FixtureClient
type FixtureReply ¶
type FixtureReply struct {
Message string `protobuf:"bytes,1,opt,name=message" json:"message,omitempty"`
}
The response message containing the greetings
func (*FixtureReply) Descriptor ¶
func (*FixtureReply) Descriptor() ([]byte, []int)
func (*FixtureReply) GetMessage ¶
func (m *FixtureReply) GetMessage() string
func (*FixtureReply) ProtoMessage ¶
func (*FixtureReply) ProtoMessage()
func (*FixtureReply) Reset ¶
func (m *FixtureReply) Reset()
func (*FixtureReply) String ¶
func (m *FixtureReply) String() string
type FixtureRequest ¶
type FixtureRequest struct {
Name string `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
}
The request message containing the user's name.
func (*FixtureRequest) Descriptor ¶
func (*FixtureRequest) Descriptor() ([]byte, []int)
func (*FixtureRequest) GetName ¶
func (m *FixtureRequest) GetName() string
func (*FixtureRequest) ProtoMessage ¶
func (*FixtureRequest) ProtoMessage()
func (*FixtureRequest) Reset ¶
func (m *FixtureRequest) Reset()
func (*FixtureRequest) String ¶
func (m *FixtureRequest) String() string
type FixtureServer ¶
type FixtureServer interface {
Ping(context.Context, *FixtureRequest) (*FixtureReply, error)
StreamPing(Fixture_StreamPingServer) error
}
type Fixture_StreamPingClient ¶
type Fixture_StreamPingClient interface {
Send(*FixtureRequest) error
Recv() (*FixtureReply, error)
grpc1.ClientStream
}
type Fixture_StreamPingServer ¶
type Fixture_StreamPingServer interface {
Send(*FixtureReply) error
Recv() (*FixtureRequest, error)
grpc1.ServerStream
}
type InterceptorOption ¶
type InterceptorOption = Option
InterceptorOption represents an option that can be passed to the grpc unary client and server interceptors. InterceptorOption is deprecated in favor of Option.
func NonErrorCodes ¶
func NonErrorCodes(cs ...codes.Code) InterceptorOption
NonErrorCodes determines the list of codes which will not be considered errors in instrumentation. This call overrides the default handling of codes.Canceled as a non-error.
type Option ¶
type Option func(*config)
Option specifies a configuration option for the grpc package. Not all options apply to all instrumented structures.
func NoDebugStack ¶
func NoDebugStack() Option
NoDebugStack disables debug stacks for traces with errors. This is useful in situations where errors are frequent and the overhead of calling debug.Stack may affect performance.
func WithAnalytics ¶
WithAnalytics enables Trace Analytics for all started spans.
func WithAnalyticsRate ¶
WithAnalyticsRate sets the sampling rate for Trace Analytics events correlated to started spans.
func WithIgnoredMetadata ¶
WithIgnoredMetadata specifies keys to be ignored while tracing the metadata. Must be used in conjunction with WithMetadataTags.
func WithIgnoredMethods ¶
WithIgnoredMethods specifies full methods to be ignored by the server side interceptor. When an incoming request's full method is in ms, no spans will be created.
func WithMetadataTags ¶
func WithMetadataTags() Option
WithMetadataTags specifies whether gRPC metadata should be added to spans as tags.
func WithRequestTags ¶
func WithRequestTags() Option
WithRequestTags specifies whether gRPC requests should be added to spans as tags.
func WithServiceName ¶
WithServiceName sets the given service name for the intercepted client.
func WithStreamCalls ¶
WithStreamCalls enables or disables tracing of streaming calls. This option does not apply to the stats handler.
func WithStreamMessages ¶
WithStreamMessages enables or disables tracing of streaming messages. This option does not apply to the stats handler.
