Analysis apparatus and analysis method

An analysis apparatus comprising:

• a memory;
• an interface communicatively coupled to a web server that hosts a web application;
• and a processor communicatively coupled to the memory and the interface;
• wherein the processor:
• receives, using the interface, an operation log including an indication of a type of device that accessed web pages of a web server, event types of events of operating the web pages, identification information on operated objects in the web pages, and operation times, and a display log of the web application;
• designates an event type to be searched for by receiving designation of the event type to be searched for, identifies display times of a web page in which an error occurred in displaying an object from the display log received, acquires operation log records including operation times prior to the display times identified in the identifying and the event type designated in the designating, counting a number of combinations of the event type and identification information on an operated object included in the operation log records acquired in the processing of the acquiring based on the type of device that accessed the web pages, analyzing whether a correlation exists between a first, kind of use condition feature values and a second kind of use condition feature values based on the counting, and outputting a result of the counting.

An analysis method comprising:

• receiving, by a processor of an analysis apparatus, at least one log concerning a web application stored in a webserver via a communication interface of the analysis apparatus;
• retrieving, by the processor, a plurality of kinds of use condition feature values from a memory of the analysis apparatus based on the log received in the receiving, wherein the plurality of kinds of use condition indicate a type of device that accessed the web application;
• analyzing, by the processor, whether a correlation exists between a first kind of use condition feature values and a second kind of use condition feature values in the plurality of kinds of use condition feature values based on the type of device that accessed the web application;
• and
• outputting, by the processor, an analysis result obtained by the analyzing.
