A server polls content, tracks changes and logs data, sending alerts in the form of email notifications, [[webhook]]s, or [[RSS]]. Typically there will also be an associated website which the user can manage their configuration. Some services also have a mobile device application which connects to a [[cloud server]] and provides alerts to the mobile device.
