A system message allows administrators to send important information to client devices. For example, you want to send information about the date and time of server maintenance to client devices. In this case, you can create a system message and send it to the required devices.
When you create a system message, you must specify the criteria for which the message must be sent to the required devices. The criteria are defined using device attributes. For example, you want to send a message to all the devices in Germany. In this case, you define the value Germany for the device attribute Country when you create the system message.
You can send a system message in multiple languages based on your requirements.
