Documentation

Overview

Package mongo provides functions to trace the mongodb/mongo-go-driver package (https://github.com/mongodb/mongo-go-driver). The minimum required version is v0.0.17 (Alpha 17). Since this driver is still in Alpha and subject to change from one release to another, stability of this package can not be guaranteed.

`NewMonitor` will return an event.CommandMonitor which is used to trace requests.

Example

package main

import (
	"context"

	"github.com/mongodb/mongo-go-driver/bson"
	"github.com/mongodb/mongo-go-driver/mongo"
	"github.com/mongodb/mongo-go-driver/mongo/clientopt"

	mongotrace "gopkg.in/DataDog/dd-trace-go.v1/contrib/mongodb/mongo-go-driver/mongo"
)

func main() {
	// connect to MongoDB
	client, err := mongo.Connect(context.Background(), "mongodb://localhost:27017",
		clientopt.Monitor(mongotrace.NewMonitor()))
	if err != nil {
		panic(err)
	}
	db := client.Database("example")
	inventory := db.Collection("inventory")

	inventory.InsertOne(context.Background(), bson.NewDocument(
		bson.EC.String("item", "canvas"),
		bson.EC.Int32("qty", 100),
		bson.EC.ArrayFromElements("tags",
			bson.VC.String("cotton"),
		),
		bson.EC.SubDocumentFromElements("size",
			bson.EC.Int32("h", 28),
			bson.EC.Double("w", 35.5),
			bson.EC.String("uom", "cm"),
		),
	))
}
