If you use NATS server, check out this sample program below to log the bucket notification added to NATS.

```go
package main

// Import Go and NATS packages
import (
 "log"
 "runtime"

 "github.com/nats-io/nats.go"
)

func main() {

 // Create server connection
 natsConnection, _ := nats.Connect("nats://yourusername:yoursecret@localhost:4222")
 log.Println("Connected")

 // Subscribe to subject

//
// -- If yes, check if the IP of entry matches local IP.
//
//	This means entry is for this instance.
//
// -- If IP of the entry doesn't match, this means entry is
//
//	for another instance. Log an error to console.
func initFederatorBackend(buckets []BucketInfo, objLayer ObjectLayer) {
	if len(buckets) == 0 {
		return
	}

	// Get buckets in the DNS
	dnsBuckets, err := globalDNSConfig.List()
