Systems and methods are described that provide a system monitor component, e.g., for a sensor network, which may include, e.g., a server component that is continuously running and monitoring zero or more networks consisting of (possibly wireless) devices, where each network may be executing a different communications protocol, such as a proprietary, platform-dependent protocol. The system monitor may maintain a system model of the networks. The system monitor may be connected with the networks through a message transport system that routes any occurring messages in a common or standard communications protocol, as well as message handlers that access either platform-abstracting gateways or the proprietary messages that the devices of one or more of the networks may use.
