+# Отчёт по лабораторной работе №4
+## Работа с брокером сообщений
+
+Выполнила: студентка гр. ИСЭбд-41 Халитова А.М.
+
+## Установка брокера сообщений RabbitMQ
+Была выполнена установка RabbitMQ и Erlang:

+![](shots/shot2.PNG) 
+
+И выполнен вход на http://localhost:15672/ в качестве гостя:

+## Разработка демонстрационных приложений
+
+Предметная область - заказ работ на исполнение. Производитель - заказчик работ. Потребитель 1 - исполнитель принимает заказ и выполняет работу. Потребитель 2 - исполнитель откладывает выполнение задачи.
+
+1. Publisher:
+```
+using System.Text;
+using RabbitMQ.Client;
+
+var factory = new ConnectionFactory { HostName = "localhost" };
+using var connection = factory.CreateConnection();
+using var channel = connection.CreateModel();
+
+channel.ExchangeDeclare(exchange: "job", type: ExchangeType.Fanout);
+Random rand = new Random();
+foreach (var item in Enumerable.Range(0, 1000))
+{
+    var message = rand.Next().ToString();
+
+    var body = Encoding.UTF8.GetBytes(message);
+    channel.BasicPublish(exchange: "job",
+            routingKey: string.Empty,
+            basicProperties: null,
+            body: body);
+
+    Console.WriteLine($" [x] Поступила работа {message}");
+    await Task.Delay(500);
+}
+
+Console.WriteLine(" Press [enter] to exit.");
+Console.ReadLine();
+
+static string GetMessage(string[] args)
+{
+    return ((args.Length > 0) ? string.Join(" ", args) : "info: Принято!");
+}
+```
+2. Consumer 1:
+```
+using System.Text;
+using RabbitMQ.Client;
+using RabbitMQ.Client.Events;
+
+var factory = new ConnectionFactory { HostName = "localhost" };
+using var connection = factory.CreateConnection();
+using var channel = connection.CreateModel();
+
+channel.QueueDeclare(queue: "accepted");
+channel.QueueBind(queue: "accepted",
+    exchange: "job",
+    routingKey: string.Empty);
+
+Console.WriteLine(" [*] Waiting for messages.");
+
+var consumer = new EventingBasicConsumer(channel);
+consumer.Received += async (model, ea) =>
+{
+    byte[] body = ea.Body.ToArray();
+    var message = Encoding.UTF8.GetString(body);
+
+    string outputText = $"Работа принята к исполнению {message}";
+    Console.WriteLine($" [x] Done. {outputText}");
+    channel.BasicAck(deliveryTag: ea.DeliveryTag, multiple: false);
+};
+channel.BasicConsume(queue: "accepted",
+    autoAck: false,
+    consumer: consumer);
+
+Console.WriteLine(" Press [enter] to exit.");
+Console.ReadLine();
+```
+
+3. Consumer 3:
+```
+using System.Text;
+using RabbitMQ.Client;
+using RabbitMQ.Client.Events;
+
+var factory = new ConnectionFactory { HostName = "localhost" };
+using var connection = factory.CreateConnection();
+using var channel = connection.CreateModel();
+
+Random rand = new Random();
+string queueName = $"denied{rand.Next()}";
+
+channel.QueueDeclare(queue: queueName);
+channel.QueueBind(queue: queueName,
+    exchange: "job",
+    routingKey: string.Empty);
+
+Console.WriteLine(" [*] Waiting for messages.");
+
+var consumer = new EventingBasicConsumer(channel);
+consumer.Received += async (model, ea) =>
+{
+    byte[] body = ea.Body.ToArray();
+    var message = Encoding.UTF8.GetString(body);
+
+    int waitTime = rand.Next(20, 90);
+    Thread.Sleep(waitTime * 100);
+
+    string outputText = $"Работа отложена {message} на {waitTime} минут";
+    Console.WriteLine($" [x] Done. {outputText}");
+    channel.BasicAck(deliveryTag: ea.DeliveryTag, multiple: false);
+};
+channel.BasicConsume(queue: queueName,
+    autoAck: false,
+    consumer: consumer);
+
+Console.WriteLine(" Press [enter] to exit.");
+Console.ReadLine();
+```
+
+## Результаты выполнения работ
+
+Запуск каждой программы по одному экземпляру:
+![](shots/shot14.PNG) 
+![](shots/shot15.PNG)
+![](shots/shot16.PNG)
+
+Результаты обработки:
+![](shots/shot17.PNG)
+![](shots/shot18.PNG)
+
+Потребителю один соответствует очередь accepted, а потребителю два - очередь denied. Как видно, первый потребитель работает без задержки, а очередь второго потребителя переполенена. Из этого следует, что скорость первого в разы выше, и он потребляет намного меньше памяти за счет постоянно пустой очереди.
+
+Запуск двух экземпляров потребителя два и по одному экземпляру потребителя один и заказчика: 
+![](shots/shot19.PNG)
+![](shots/shot20.PNG)
+
+Ситуация в очередью потребителя один не изменилась, а экземпляры потребителя два теперь затрачивают в 2 раза больше времени и памяти, их очереди так же переполнены, как и в ситуации выше.
