### Homebrew (recommended)

Run the following command to install the latest stable MinIO package using [Homebrew](https://brew.sh/). Replace ``/data`` with the path to the drive or directory in which you want MinIO to store data.

```sh

          "expr": "minio_node_drive_used_bytes{job=~\"$scrape_jobs\",server=\"$server\"}",
          "interval": "",
          "legendFormat": "Used [{{drive}}]",
          "refId": "B"
        },
        {
          "datasource": {
            "type": "prometheus",
            "uid": "${DS_PROMETHEUS}"
          },
          "exemplar": true,
