# 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.
