SYSTEM, METHOD, AND SEARCH ENGINE FOR CONFIRMING CONDITION OF PROCESS SEQUENTIALLY PERFORMED BY A PLURALITY OF SERVERS

PROBLEM TO BE SOLVED: To provide a system capable of confirming conditions of processes sequentially performed by a plurality of servers to identify a server causing a problem without interrupting the sequentially performed processes.SOLUTION: A data analysis part (11) of a search engine (1) consists of a plurality of analysis servers (20) and an aggregation server (30). The respective analysis servers (20) carry out pretreatment for forming a search index by sequentially performing processes on crawl data identified by URLs, and store transaction logs of the processes. When receiving a condition confirmation request designating a URL from the aggregation server (30), the analysis server (20) extracts a transaction log corresponding to the URL, and transmit it to the aggregation server (30). From the received transaction log, the aggregation server (30) specifies description of a process in each of the analysis servers (20).
