Message log removing apparatus, message log removing method, and message log removing program

摘要

A message log removal apparatus includes a processor. The processor prepares, for each packet, a packet record including a reception time, a packet size, destination information, and source information. The processor prepares, on basis of the packet records, message records each corresponding to a pair of a request and a response. Each message record includes a first reception time, a second reception time, a request size, a response size, first source information, and first destination information. The request is constructed of first packets transmitted from the first transmission source to the first transmission destination. The response is constructed of second packets transmitted from the first transmission destination to the first transmission source. The processor removes a first message record from among the message records on basis of the request size, the response size, the first source information, and the first destination information included in the first message record.
