-# Отчёт по лабораторной работе №2
-Выполнил: студент гр. ИСЭбд-41 Михайлов Юрий.
-
-Задание программы 1: Ищет в каталоге /var/data самый большой по объёму файл и перекладывает его в /var/result/data.txt.
-Задание программы 2: Ищет набольшее число из файла /var/data/data.txt и сохраняет его вторую степень в /var/result/result.txt.
-
-# Создание приложений
-
-Создаем 2 приложения с помощью команды:
-
-```yam
-    dotnet new console -o  worker-1
-    dotnet new console -o  worker-2
-```
-Пр№ 1: Ищет в каталоге /var/data самый большой по объёму файл и перекладывает его в /var/result/data.txt.
-
-[Текст программы worker-1](worker-1/Program.cs)
-
-Пр№ 2: Ищет набольшее число из файла /var/data/data.txt и сохраняет его вторую степень в /var/result/result.txt.
-
-[Текст программы worker-2](worker-2/Program.cs)
-
-Cоздали файл [.gitignore](.gitignore) с помощью команды dotnet new gitignore.
-
-# Настройка окуржения
-
-Для обеспечения взаимодействия между двумя приложениями мы применили следующий подход:
-
-Для каждого приложения были разработаны файлы Dockerfile ([программа 1](worker-1/Dockerfile), [программа 2](worker-1/Dockerfile)) с подробным описанием процесса сборки.
-
-Также был создан файл [docker-compose.yml](docker-compose.yml), в котором указан манифест для запуска распределённого приложения.
-
-Также был создан файл [.dockerignore](.dockerignore) и дополнен [.gitignore](.gitignore), чтобы исключить для сборки и коммита всё лишнее.
-
-# Сборка и запуск
-
-В каталог ./data помещены 2 файла: another_data.txt и data.txt.
-Для запуска приложения необходимо ввести команду `docker compose up --build`.
-
-Результат запуска после сборки:
-```
-[+] Running 3/3
- ✔ Network lab_2_default       Created                                                                                                                   0.1s

-lab_2-worker-2-1 exited with code 0
-```
-В результате 1 работы в каталоге `./result` создался файл `data.txt`.
-В результате 2 работы в каталоге `./result` создался файл `result.txt` с содержимым `196`, что соответствует входным данным.

+
+static string GetMessage(string[] args)

+2. Consumer 1:
+```
+using System.Text;

+using RabbitMQ.Client.Events;
+
+var factory = new ConnectionFactory { HostName = "localhost" };
+using var connection = factory.CreateConnection();

+
+3. Consumer 3:

+using RabbitMQ.Client.Events;
+
+var factory = new ConnectionFactory { HostName = "localhost" };
+using var connection = factory.CreateConnection();

+Random rand = new Random();
+string queueName = $"denied{rand.Next()}";

+channel.BasicConsume(queue: queueName,
+    autoAck: false,
+    consumer: consumer);
+
+Console.WriteLine(" Press [enter] to exit.");
+Console.ReadLine();
+```
+
+## Результаты выполнения работы

+![](pic/12.PNG)
+![](pic/13.PNG)
+
+Результаты обработки:
+![](pic/14.PNG)
+![](pic/15.PNG)
+
+Вывод: Consumer_2 нагружает меньше памяти, чем Consumer_1 и принимает сообщения гораздо быстрее, тем самым не позволяя очереди накапливать огромное количество сообщений
