Introduction

This data source is configured to subscribe to one or more queues (topics) on a RabbitMQ Server. The payload for each message published to the specified queue(s) will consist of the raw bytes received.

Property Details

Here is an overview of the parameters for configuring the RabbitMQ data source:

Auth Mechanism Options

Here is an overview of the RabbitMQ Auth Mechanism Options:

Queue Options

Here are explanations for the Queue Options associated with the RabbitMQ data source:

TLS Version Options

Here is a tabular representation of the TLS version options for RabbitMQ:

Configuration of the RabbitMQ data source node

Every device should include the Device Information, Data Source, and Filter nodes. To create a device, click the + icon located on the top-left side of the ‘Create Device’ screen as shown in Figure 1. This action opens a configuration window for the device. Within this screen, users can select and add the necessary nodes. To add a node, access the ‘Add Node’ window, as illustrated in Figure 2.

Figure 1 - Create Device

The window below enables the user to add and configure a data source node.

Figure 2 - Add Node

The RabbitMQ node consists of features to:

1. Configure the node: Allows users to customize and adjust the settings of the selected node according to their requirements.
2. Show nodes compatible with the selected node: Displays nodes that are compatible with the selected node, providing a streamlined view of related options.
3. Bring up the help centre for the node: Directs users to the help centre for the selected node, offering detailed guidance and documentation.
4. Copy icon: Permits users to duplicate the selected node, facilitating efficient replication of configurations.
5. Delete the node: Enables users to remove the selected node from the configuration, allowing for adjustments and refining the setup.

Figure 3 - Node Features

Upon selecting the configure button in Figure 3, the window for the RabbitMQ data source node is presented as illustrated in Figure 4. In this interface, users can input and edit relevant information to configure the RabbitMQ data source.

The following explanations help clarify the purpose and significance of each parameter in the configuration of the RabbitMQ data source.

1. Data Source Options: This feature enables users to establish the origin and method type of the data source.
   • Data source type
   • Configuration path
2. Servers - Port Number: Specifies the port number for the RabbitMQ servers.
3. Topics: Users post their routing key, and the system selects the topic based on that input. Parse topics are simplified representations of these topics.
4. Virtual Host: Represents a path not related to the server.
5. Authentication Mechanism: Requires a username and password if set.
6. Use TLS and Validate TLS Certificate: These checkboxes pertain to security certificates, with “Use TLS” indicating whether to establish a secure TLS connection, and “Validate TLS Certificate” specifying whether to validate the RabbitMQ server’s TLS certificate during connection.
7. Queue Options: Additional details about the queue configuration.
