Prerequisites to using the mqtt() source

Using the current implementation of the mqtt() source has the following prerequisites:

• Installing the eclipse-paho-mqtt-c library.

  Note

  The default package manager for some Linux operating systems contains the eclipse-paho-mqtt-c library, but depending on your OS, you may have to install the library manually. For more information about how you can download and install the eclipse-paho-mqtt-c library, see Eclipse Paho on the Eclipse Foundation website.

• Having a broker entity in a functional MQTT system.

  Note

  In your configuration, you will specify the broker entity of your MQTT system in the address() option of your mqtt() source.
