### 2. Configure authentication type for Prometheus metrics

MinIO supports two authentication modes for Prometheus either `jwt` or `public`, by default MinIO runs in `jwt` mode. To allow public access without authentication for prometheus metrics set environment as follows.

```
export MINIO_PROMETHEUS_AUTH_TYPE="public"
minio server ~/test
```

### 3. Configuring Prometheus

| `minio_api_requests_rejected_timestamp_total`  | `counter` | Total number of requests rejected for invalid timestamp | `type,pool_index,server`         |
| `minio_api_requests_rejected_invalid_total`    | `counter` | Total number of invalid requests                        | `type,pool_index,server`         |

# How to monitor MinIO server with Grafana [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

[Grafana](https://grafana.com/) allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture.

- A maximum of 100M inside a single zip is allowed. However, a reasonable limit of 100,000 files inside a single ZIP archive is recommended for best performance and memory usage trade-off.

## Content-Type

```bash
~ mc admin config set myminio compression
```

To enable compression for all content, no matter the extension and content type
(except for the default excluded types) set BOTH extensions and mime types to empty.

```bash
~ mc admin config set myminio compression enable="on" extensions="" mime_types=""
```

The compression settings may also be set through environment variables.
