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.
