1. A system comprising: at least a first device of at least one device network that is configured to collect monitor data associated with the at least one device network, using a first instance of a core monitor service and at least a first monitor service module at a first logical layer of a hierarchical, multi-tiered monitor architecture; and at least a second device of the at least one device network that is configured to propagate at least a portion of the monitor data from the first device up through the hierarchical, multi-tiered monitor architecture, using a second instance of the core monitor service and at least a second monitor service module at a second logical layer of the hierarchical, multi-tiered monitor architecture, wherein the core monitor service is configured to execute a first subset of monitor functions which are generic with respect to the logical layers and to the devices, including sending and receiving monitor messages to propagate the at least a portion of the monitor data, and wherein the first monitor service module and the second monitor service module are separable from the core service with respect to installation or removal thereof, and adapted for execution of at least a second subset of monitor functions defined with respect to their respective devices and/or logical layers, the second subset of monitor functions including processing the at least a portion of the monitor data in conjunction with the first instance and the second instance of the core monitor service, respectively, to thereby formulate the monitor messages, wherein the at least the first device includes a smart item device that is included within the at least one device network, and the smart item device is configured to implement the first instance of the core monitor service and the first monitor service module using an edge monitor service at which the monitor data is collected, wherein the at least the second device includes a group leader device that is included within the at least one device network, and the group leader device is configured to implement the second instance of the core monitor service and the second monitor service module using a group leader monitor service at which the monitor data is processed for transmission, wherein the at least the second device includes a local device associated with the group leader monitor service, and the local device is configured to implement a third instance of the core monitor service and at least a third monitor service module using a local monitor service at which the processed monitor data is stored, and wherein the at least the second device includes a global device associated with the local monitor service, and the global device is configured to implement a fourth instance of the core monitor service and at least a fourth monitor service module using a global monitor service at which the stored monitor data is used to update global monitor data.
4. The system of claim 1 wherein the first monitor service module includes a system adaptor that is configured to collect service metadata associated with a service on the first device and/or device metadata associated with the first device.
