Node level Replication metrics can be viewed in the Grafana dashboard using [json file here](https://raw.githubusercontent.com/minio/minio/master/docs/metrics/prometheus/grafana/replication/minio-replication-node.json)

MinIO server configuration file allows users to provide topology that allows for heterogeneous hostnames, allowing MinIO to deployed in pre-existing environments without any further OS level configurations.

### Usage

```
minio server --config config.yaml
```

## Request, System and Cluster Metrics

At a high level metrics are grouped into three categories, listed in the following sub-sections. The path in each of the tables is relative to the top-level endpoint.

### Request metrics 

These are metrics about requests served by the (current) node.

	if h.clientToken == bgHealingUUID {
		// For background heal do nothing, do not spawn an unnecessary goroutine.
	} else {
		// Launch top-level background heal go-routine
		go h.healSequenceStart(objAPI)
	}

	b, err := json.Marshal(madmin.HealStartSuccess{
		ClientToken:   clientToken,
		ClientAddress: h.clientAddress,
		StartTime:     h.startTime,

	return false
}

// ReplicationStats holds the global in-memory replication stats
type ReplicationStats struct {
	// map of site deployment ID to site replication status
	// for site replication - maintain stats at global level
	srStats *SRStats
	// active worker stats
	workers *ActiveWorkerStat
	// queue stats cache
	qCache queueCache

	pCache proxyStatsCache
	// mrf backlog stats
	mrfStats ReplicationMRFStats

# Cluster Metrics

MinIO collects the following metrics at the cluster level.
Metrics may include one or more labels, such as the server that calculated that metric.

These metrics can be obtained from any MinIO server once per collection by using the following URL:

```shell
https://HOSTNAME:PORT/minio/v2/metrics/cluster
```

Replace ``HOSTNAME:PORT`` with the hostname of your MinIO deployment.

	info := madmin.GetSysServices(context.Background(), globalLocalNodeName)
	return madminSysServices.NewJSONWith(&info), nil
}

// GetSysErrorsHandler - returns system level errors
func (s *peerRESTServer) GetSysErrorsHandler(_ *grid.MSS) (*grid.JSON[madmin.SysErrors], *grid.RemoteErr) {
	info := madmin.GetSysErrors(context.Background(), globalLocalNodeName)

	globalInternodeTransport = NewInternodeHTTPTransport(0)()

	initHelp()

	resetTestGlobals()

	globalIsCICD = true

	os.Exit(m.Run())
}

}

// SiteReplicationSys - manages cluster-level replication.
type SiteReplicationSys struct {
	sync.RWMutex

	enabled bool

	// In-memory and persisted multi-site replication state.
	state srState

	iamMetaCache srIAMCache
}

		// Objects matching prefixes should not leave delete markers,
		// dramatically reduces namespace pollution while keeping the
		// benefits of replication, make sure to apply version suspension
		// only at bucket level instead.
		VersionSuspended: globalBucketVersioningSys.Suspended(bucket),
	})
	if err != nil && !isErrVersionNotFound(err) { // VersionNotFound would be reported by pool that object version is missing on.
