![Events Diagram](../assets/images/******@****.***)

Here’s a [sample event listener](https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PrintEventsNonConcurrent.java) that prints each event with a timestamp.

```java
class PrintingEventListener extends EventListener {
  private long callStartNanos;

/**
 * A BuildService which monitors a few tasks (in both build-logic and main build) and collects information for build scan.
 * It's currently implemented by two use cases:
 * 1. Collect cache misses for compilation tasks and publish a `CACHE_MISS` tag for build scan.

 *
 * Steps to run in your own code
 *
 * 1. In your main method `WireSharkListenerFactory.register()`
 * 2. Create Listener factory `val eventListenerFactory = WireSharkListenerFactory(
logFile = File("/tmp/key.log"), tlsVersions = tlsVersions, launch = launch)`

## Como Parece

Vamos primeiro usar o código e ver como funciona, e depois voltaremos para entender o que está acontecendo.

## Crie um `main.py`
Copie o exemplo em um arquivo `main.py`:

```Python
{!../../docs_src/security/tutorial001.py!}
```

## Execute-o
