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:
enmac-collector.setup command.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:
snap <start|stop|restart> enmac-collectorsnap logs enmac-collectorsnap logs enmac-collector -fAvailable Commands
This package includes several utility commands. Run enmac-collector --help for a full list.
enmac-collector.setup
Updates the collector's setup configuration.
(Run `enmac-collector.setup --help` for details)
enmac-collector.version
Print the currently installed version of the snap.
enmac-collector.license

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.
Tumbleweed:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
Leap 15.x:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
If needed, Swap out openSUSE_Leap_15. for, openSUSE_Leap_16.0 if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install Prevas Collector, simply use the following command:
sudo snap install enmac-collector
Browse and find snaps from the convenience of your desktop using the snap store snap.
