A processing method includes: collecting processing information indicating a processing state of an application executed by an information processing device and operational information indicating operational states of processing elements that are identified on the basis of configuration information stored in a storage unit and are involved in the execution of the application; determining whether or not there is a correlation between the processing state and an operational state of each of the processing elements on the basis of the processing information and the operational information when a delay of a process of the application is detected on the basis of the processing information; and extracting, from among the processing elements, a processing element of which an operational state has a correlation with the processing state on the basis of the determination.
