supports a bearer token approach to authenticate prometheus scrape requests, override the default Prometheus config with the one generated using mc. To generate a Prometheus config for an alias, use [mc](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart) as follows `mc admin prometheus generate <alias> [METRIC-TYPE]`. The valid values for METRIC-TYPE are `cluster`, `node`, `bucket` and `resource` and if not mentioned, it defaults to `cluster`.

The command will generate the `scrape_configs`...

```sh
mc admin update <minio alias, e.g., myminio>
```

- For deployments without external internet access (e.g. airgapped environments), download the binary from <https://dl.min.io> and replace the existing MinIO binary let's say for example `/opt/bin/minio`, apply executable permissions `chmod +x /opt/bin/minio` and proceed to perform `mc admin service restart alias/`.

## Configuring Site Replication

- Configure an alias in `mc` for each of the sites. For example if you have three MinIO sites, you may run:

```sh
mc alias set minio1 https://minio1.example.com:9000 adminuser adminpassword
mc alias set minio2 https://minio2.example.com:9000 adminuser adminpassword
mc alias set minio3 https://minio3.example.com:9000 adminuser adminpassword
```

or

```sh
