Claim 9:
10. A remote monitoring method implemented by a remote monitoring system including a plurality of data collection adaptors each configured to collect apparatus data including information representing at least either an operational situation or operational detail of one or more installed apparatuses from the one or more installed apparatuses being air conditioning apparatuses operated to condition air, and a data aggregation server configured to communicate with the plurality of data collection adaptors and configured to receive and aggregate the apparatus data that the plurality of data collection adaptors have each collected, the remote monitoring method comprising:
with each data collection adaptor including
a collection side storage configured to store collection side definition information defining one or more items for extracting the apparatus data from a set of data including the apparatus data acquired from the one or more installed apparatuses,
acquiring the set of data from the one or more installed apparatuses;
extracting the apparatus data from the set of data by using the collection side definition information;
when a predetermined condition is satisfied, making a request to the data aggregation server to update the collection side definition information; and

with the data aggregation server including
an aggregation side storage configured to store aggregation side definition information defining the one or more items each of the plurality of data collection adaptors uses for extracting the apparatus data from the set of data acquired by the data collection adaptor,
when the request is received from one or more of the data collection adaptors, transmitting information for updating based on the aggregation side definition information to the one or more of the data collection adaptors,

further comprising, by each of the one or more of the data collection adaptors,
updating the collection side definition information by using the information for updating received from the data aggregation server,

wherein the plurality of data collection adaptors have
unique second identifiers for identifying the respective plurality of data collection adaptors,

wherein the aggregation side definition information defines
the one or more items associated with one or more of the second identifiers,

wherein the request from the data collection adaptor includes
the set of data from which the data collection adaptor has not been able to extract the apparatus data in the extraction step, and the second identifier identifying the data collection adaptor,

further comprising, by the data aggregation server,
when the request is received, searching in the aggregation side definition information for the one or more of the second identifiers including the second identifier included in the request; when the one or more of the second identifiers are included in the aggregation side definition information, performing an extraction process of extracting, from the aggregation side definition information, the apparatus data indicated in the set of data included in the request by using the one or more items associated with the one or more of the second identifiers; and when the apparatus data is extracted by the extraction process, extracting, from the aggregation side definition information, the one or more items associated with the one or more of the second identifiers, and
transmitting the information for updating including the one or more items extracted by the data aggravation server to the data collection adaptor, which is a source of the request, and

by each of the data collection adaptors, updating the collection side definition information using the information for updating from the data aggregation server and using the updated collection side definition information to extract the apparatus data.
