Management device, management system, management method, and program for providing virtual and real resource information values

A management system, comprising:

• a device connected to a network;
• a data model constructor including:
• a display to display a data model including real resource information associated with the device and virtual resource information associated with a calculation result of calculation performed using a value of the real resource information, and
• a setting requester to receive a setting request for setting the calculation, the data model constructor being configured to construct the data model;
• an application device including:
• an acquisition requester to receive an acquisition request generated based on the data model to acquire the value of the real resource information or a value of the virtual resource information, and
• a data processor to process a value included in a response returned in response to the acquisition request;
• a receiver to receive the acquisition request from the acquisition requester;
• a collector to collect a value from the device associated with the real resource information;
• a calculator to perform the calculation to obtain the calculation result;
• a real resource information acquirer to acquire the value of the real resource information by causing the collector to collect the value from the device associated with the real resource information;
• a virtual resource information acquirer to acquire the value of the virtual resource information by causing the calculator to perform the calculation using the value of the real resource information;
• and
• a responder to return, in response to the receiver receiving the acquisition request for the real resource information, a first response including the value of the real resource information acquired by the real resource information acquirer to the application device, and to return, in response to the receiver receiving the acquisition request for the virtual resource information, a second response including the value of the virtual resource information acquired by the virtual resource information acquirer to the application device, wherein
• in a case where (i) the calculation uses values of multiple pieces of the real resource information, including the value of the real resource information from the device, and (ii) corresponding respective, time points at which the values are collected, by the collector, from devices associated with the multiple pieces of the real resource information, including the device, fail to match each other, the real resource information acquirer causes the collector to collect the values again from the devices associated with the multiple pieces of the real resource information, and
• the time points failing to match each other refers to collection time points that are not equal to one another or within a predetermined time difference between the collection time points.

A non-transitory computer-readable recording medium storing a program for causing a computer for managing resource information values provided based on a data model that includes real resource information associated with a device connected to a network, and virtual resource information associated with a calculation result of calculation performed using a value of the real resource information to function as

• a receiver to receive an acquisition request generated based on the data model to acquire the value of the real resource information or a value of the virtual resource information,
• a real resource information acquirer to acquire the value of the real resource information by causing a collector to collect a value from the device associated with the real resource information,
• a virtual resource information acquirer to acquire the value of the virtual resource information by causing a calculator to perform the calculation using the value of the real resource information, and
• a responder to return, in response to the receiver receiving the acquisition request for the real resource information, a first response including the value of the real resource information acquired by the real resource information acquirer to a requester of the acquisition request, and to return, in response to the receiver receiving the acquisition request for the virtual resource information, a second response including the value of the virtual resource information acquired by the virtual resource information acquirer to the requester of the acquisition request, wherein
• in a case where (i) the calculation uses values of multiple pieces of the real resource information, including the value of the real resource information from the device, and (ii) corresponding respective time points at which the values are collected, by the collector, from devices associated with the multiple pieces of the real resource information, including the device, fail to match each other, the real resource information acquirer causes the collector to collect the values again from the devices associated with the multiple pieces of the real resource information, and
• the time points failing to match each other refers to collection time points that are not equal to one another or within a predetermined time difference between the collection time points.
