A diagnosis device includes a first acquisition unit, a second acquisition unit, and an associating unit. The first acquisition unit is configured to acquire, from a machine tool, context information including at least a monitoring specifying number identifying a machining process. The second acquisition unit is configured to acquire detection information output from a detection unit installed for the machine tool. The associating unit is configured to associate the monitoring specifying number included in the context information acquired by the first acquisition unit and the detection information acquired by the second acquisition unit.
