You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: telemetry.go
    path of file: ./repos/convoy/internal/telemetry
    
    the code of the file until where you have to start completion: package telemetry

import (
	"context"
	"io"

	"github.com/frain-dev/convoy/datastore"
	"github.com/frain-dev/convoy/pkg/log"
)

const (
	DailyEventCount         string = "Daily Event Count"
	DailyActiveProjectCount string = "Daily Active Project Count"
)

type backend interface {
	io.Clo
    
func (t *Telemetry) Identify(ctx context.Context, instanceID string) error {
	isEnabled := t.config.IsAnalyticsEnabled
	if !isEnabled {
		return nil
	}

	for _, b := range t.backends {
		go func(b backend) {
			err := b.Identify(ctx, instanceID)
			if err != nil {
				t.Logger.Error(err)
			}

			err = b.Close()
			if err != nil {
				t.Logger.Error(err)
			}
		}(b)
	}

	return nil
}
