# MQTT Collector config.

#### Example configuration

Example configuration for broker mode using password authentication, certificate-based TLS and IP sourcefiltering. The sample points array shows all possible sample types.

          Note:

          

To have the collected data delivered somewhere, a data-server configuration must be added too.
