### 3.3 Use GnuTLS (for Windows) to Generate a Certificate

This section describes how to use GnuTLS on Windows to generate a certificate.

restart ``` Below command enables all incoming traffic to ports ranging from 9000 to 9010. ```sh iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT service iptables restart ``` ## Test MinIO Connectivity ### Test using MinIO Console MinIO Server comes with an embedded web based object browser. Point your web browser to <http://127.0.0.1:9000> to ensure your server has started successfully. > NOTE: MinIO runs console on random port by default, if you wish to choose a specific port use `--console-address`...

And then another background task generated at the *path operation function* will write a message using the `email` path parameter.

## Technical Details { #technical-details }

The class `BackgroundTasks` comes directly from <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">`starlette.background`</a>.

An optional prefix sets a non-decimal base: <code>0b</code> or <code>0B</code>
for binary, <code>0</code>, <code>0o</code>, or <code>0O</code> for octal,
and <code>0x</code> or <code>0X</code> for hexadecimal
[<a href="#Go_1.13">Go 1.13</a>].
A single <code>0</code> is considered a decimal zero.
In hexadecimal literals, letters <code>a</code> through <code>f</code>
and <code>A</code> through <code>F</code> represent values 10 through 15.

    /**
     * Checks the acquisition-ordering between {@code this}, which is about to be acquired, and the
     * specified {@code acquiredLock}.
     *
     * <p>When this method returns, the {@code acquiredLock} should be in either the {@code
     * preAcquireLocks} map, for the case in which it is safe to acquire {@code this} after the
     * {@code acquiredLock}, or in the {@code disallowedPriorLocks} map, in which case it is not
     * safe.

Por exemplo:

* **Processamento de áudio** ou **imagem**
* **Visão Computacional**: uma imagem é composta por milhões de pixels, cada pixel tem 3 valores / cores, processar isso normalmente exige alguma computação em todos esses pixels ao mesmo tempo

. . .
```

Refer [Prometheus documentation](https://prometheus.io/docs/introduction/first_steps/) for more details.

### 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"

    * If the serialization type is 'application/json':
    * If serialization fails, and the original status code was an failure (e.g. 4xx or 5xx), the original status code will be returned.
