1. A distributed system comprising:
a plurality of edge devices which are each at least one of an automatically operable moving body and an automatically operable equipment,
wherein the plurality of edge devices convert state data representing states of components that are each a constituent of a replaceable unit forming the edge device, into diagnostic data according to a predetermined diagnostic algorithm; and
a diagnostic data computer which acquires first diagnostic data from a first edge device, refers to a database regarding a configuration of the first edge device including a first component of the first edge device, and specifies a second edge device that employs a second component related to the first component of the first edge device,
wherein the diagnostic data computer determines a degree of relevance between the first edge device and the second edge device and determines a possibility of occurrence of at least one of an abnormality and a failure in the second edge device based on the degree of relevance and the diagnostic data acquired from the second edge device, and
wherein the diagnostic data computer instructs the second edge device having a possibility of occurrence of at least one of the abnormality and the failure to change a collection condition for collecting the state data of the second component and transmit second diagnostic data from the second edge device.
