Prevas Collector

The Prevas Collector (enmac-collector) is the official snap package for the Prevas Cloud data acquisition agent. It functions as a secure and reliable data pipeline, designed to connect industrial operational technology (OT) environments to the Prevas Cloud platform.

This snap is a key component of the Prevas Digital Suite for Industrial Internet of Things (IIoT). Its primary role is to gather data from various industrial protocols, such as Modbus TCP and OPC UA, and transmit it to the Prevas Cloud platform. This enables near real-time monitoring, data analysis, and visualization of process trends, hardware conditions, and alarms.

The snap is designed for high reliability, running as a persistent background service (daemon) that restarts automatically on failure. It supports both amd64 (standard servers) and arm64 (IoT gateways, Raspberry Pi) architectures, making it suitable for a wide range of industrial hardware.

Initial Configuration

A Prevas Cloud subscription is required to use the collector.

To function, the collector needs a setup configuration file generated by the Prevas Cloud platform. This file can be provided to the snap in two ways:

1. Manual transfer: Using the enmac-collector.setup command.
2. Automated injection (coming soon): Using a specially prepared USB stick for automated configuration.

Detailed guidance on generating the configuration file and using both setup methods is available in your Prevas Cloud portal at https://prevascloud.com.

Service Management

The collector runs as a background service. You can manage it using standard snap commands:

• Start, stop or restart the service: snap <start|stop|restart> enmac-collector
• View service logs: snap logs enmac-collector
• Follow logs in real-time: snap logs enmac-collector -f
