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 "gopkg.in/DataDog/dd-trace-go.v1/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 "gopkg.in/DataDog/dd-trace-go.v1/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)
}
}

}
The request message containing the user's name.
func (*FixtureRequest) Descriptor ¶ added in v1.0.0
func (*FixtureRequest) Descriptor() ([]byte, []int)
func (*FixtureRequest) GetName ¶ added in v1.0.0
func (m *FixtureRequest) GetName() string

func (m *FixtureRequest) String() string
type FixtureServer ¶ added in v1.0.0
type FixtureServer interface {
Ping(context.Context, *FixtureRequest) (*FixtureReply, error)
StreamPing(Fixture_StreamPingServer) error
}
type Fixture_StreamPingClient ¶ added in v1.1.0
type Fixture_StreamPingClient interface {
Send(*FixtureRequest) error
Recv() (*FixtureReply, error)
grpc1.ClientStream
}
type Fixture_StreamPingServer ¶ added in v1.1.0
type Fixture_StreamPingServer interface {
Send(*FixtureReply) error
Recv() (*FixtureRequest, error)
grpc1.ServerStream
}
type InterceptorOption ¶ added in v1.0.0
type InterceptorOption func(*config)
InterceptorOption represents an option that can be passed to the grpc unary client and server interceptors. InterceptorOption is deprecated in favor of Option.
