Setup

To instrument your MongoDB usage, you’ll need to import the OpenTelemetry official instrumentation package: 
import "go.opentelemetry.io/contrib/instrumentation/go.mongodb.org/mongo-driver/mongo/otelmongo"
Before initializing your MongoDB connection, add the otelmongo.NewMonitor() as a monitor in the connection options as shown in the example below. 
opts := options.Client()
opts.Monitor = otelmongo.NewMonitor()
opts.ApplyURI("mongodb://your.mongo.host:27017")
client, err := mongo.Connect(ctx, opts)
if err != nil {
	panic(err)
}
At this time the Mongo instrumentation reports all queries in an unsanitized fashion. This means that any PII data is sent to AppSignal, like email addresses and passwords. This will be configurable in a future version of the Mongo instrumentation.
