The analyzer includes a path information obtainer that extracts a component that a first function among a plurality of functions sometimes uses and sometimes does not use as an undetermined component beforehand; a detector that detects whether the undetermined component is used during operation; and a specifier that specifies, when a problem arises during the operation, a problem component, as a problem point, among one or more components based on path information including the one or more components that each of the plurality of functions uses and being obtained for the function beforehand, operation information obtained during the operation, and a result of detecting using of the undetermined component. This configuration makes it possible to specify an exact problem point.
