# Istio CNI Node Agent

The Istio CNI Node Agent is responsible for several things

- Install an Istio CNI plugin binary on each node's filesystem, updating that node's CNI config in e.g (`/etc/cni/net.d`), and watching the config and binary paths to reinstall if things are modified.

OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(new LoggingInterceptor())
    .build();

Request request = new Request.Builder()
    .url("http://www.publicobject.com/helloworld.txt")
    .header("User-Agent", "OkHttp Example")
    .build();

Response response = client.newCall(request).execute();
response.body().close();
```

Portanto, você pode usar `user_agent` como faria normalmente no código Python, em vez de precisar colocar as primeiras letras em maiúsculas como `User_Agent` ou algo semelhante.

Se por algum motivo você precisar desabilitar a conversão automática de sublinhados para hífens, defina o parâmetro `convert_underscores` de `Header` para `False`:

| `minio_cluster_replication_average_link_latency_ms`        | Average replication link latency in milliseconds                                                         |
| `minio_cluster_replication_max_link_latency_ms`            | Maximum replication link latency in milliseconds seen since server start                                 |
