A non-transitory computer-readable recording medium stores therein an analysis program for causing a computer to execute a process including: acquiring information capable of identifying functions in operation which is obtained by a sampling by a plurality of operating systems at each first time interval with respect to programs in operation; totaling a number of pieces of the acquired information for each function; generating time-series data indicating the number of pieces of the information at each second time interval for the function whose number of pieces of the information satisfies a prescribed condition; analyzing a causal relationship between the functions based on the time-series data; and outputting an analysis result of the causal relationship between the functions.
