• Status Code, Duration, Timestamp, Service Name, Service Method, IP, Metadata Fields and User Agent.

Usage

import (
	"github.com/oceanbolt/grpc-zerolog"
)

func main() {
	// With global Zerolog logger.
	grpc.NewServer(
		zerolog.UnaryInterceptor(),
	)

	// With custom Zerolog instance.
	log := zerolog.New(os.Stdout)
	grpc.NewServer(
		zerolog.UnaryInterceptorWithLogger(&log),
	)
}
