EasyNetQ.Client.Management is a thin C# client for the RabbitMQ Management HTTP API. Before you can use it, you have to enable the RabbitMQ Management Plugin.

Using the management API it's possible to automate various management, monitoring and set-up tasks including:

  • Declare, list and delete exchanges, queues, bindings, users, virtual hosts and permissions.
  • Monitor queue length, message rates globally and per channel, data rates per connection, etc.
  • Force close connections, purge queues.

To install EasyNetQ.Client.Management use NuGet:

PM> Install-Package EasyNetQ.Management.Client

To give an overview of the sort of things you can do with EasyNetQ.Client.Management, have a look at this code which walks through a scenario creating a new virtual host, user, some permissions and then creating an exchange, a queue, and binding them together. Finally it publishes a test message to the exchange and checks that it has arrived on the queue:

var initial = new ManagementClient("http://localhost", "guest", "guest");

// first create a new virtual host
var vhost = initial.CreateVirtualHost("my_virtual_host");

// next create a user for that virutal host
var user = initial.CreateUser(new UserInfo("mike", "topSecret"));

// give the new user all permissions on the virtual host
initial.CreatePermission(new PermissionInfo(user, vhost));

// now log in again as the new user
var management = new ManagementClient("http://localhost", user.Name, "topSecret");

// test that everything's OK

// create an exchange
var exchange = management.CreateExchange(new ExchangeInfo("my_exchagne", "direct"), vhost);

// create a queue
var queue = management.CreateQueue(new QueueInfo("my_queue"), vhost);

// bind the exchange to the queue
management.CreateBinding(exchange, queue, new BindingInfo("my_routing_key"));

// publish a test message
management.Publish(exchange, new PublishInfo("my_routing_key", "Hello World!"));

// get any messages on the queue
var messages = management.GetMessagesFromQueue(queue, new GetMessagesCriteria(1, false));

foreach (var message in messages)
    Console.Out.WriteLine("message.payload = {0}", message.payload);
