1. A data analysis apparatus comprising processing circuitry
to acquire series data having a character string related to an information system to be analyzed as an element and series data having a numerical value indicating a state of a device constituting the information system as an element, each of the series data having the character string and the series data having the numerical value having an index that enables comparison of element order relations within series and between series,
to classify the element of each piece of the series data having the character string and each piece of the series data having the numerical value into one of a plurality of classification classes,
to output each piece of the series data with one of a plurality of classification values indicating one of the plurality of classification classes as an element,
to perform integration of a first portion of the series data having a first classification value of the character string among the plurality of classification values as an element and a second portion of the series data having a second classification value of the numerical value among the plurality of classification values as an element into one piece of series data, and
to perform detection of an occurrence of a frequent pattern which is a combination of frequently occurring elements, using the one piece of series data obtained by the integration.
