After Prometheus is configured, you can use Grafana to visualize MinIO metrics. Refer the [document here to setup Grafana with MinIO prometheus metrics](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/grafana/README.md).

## List of metrics exposed by MinIO

- MinIO exports Prometheus compatible data by default as an authorized endpoint at `/minio/v2/metrics/cluster`. 

# Metrics Version 3

In metrics version 3, all metrics are available under the following base endpoint:

```
/minio/metrics/v3
```

To query metrics of a specific type, append the appropriate path to the base endpoint.
Querying the base endpoint returns "404 Not Found."

Metrics are organized into groups at paths **relative** to the top-level endpoint above.

The additional node specific metrics which include additional go metrics or process metrics are exposed at
`<Address for MinIO Node>/minio/v2/metrics/node`.

The additional bucket specific metrics which include additional go metrics or process metrics are exposed at
`<Address for MinIO Node>/minio/v2/metrics/bucket`.

The additional resource specific metrics which include additional go metrics or process metrics are exposed at
