Abstract: A measurement apparatus includes a communication device configured to obtain a packet being transmitted between a server apparatus and a communication apparatus in a network, a memory, and a processor coupled to the memory and configured to calculate round-trip time between the communication apparatus and the server apparatus, and measure a data transfer rate between the communication apparatus and the server apparatus based on a data volume included in a second packet having a length equal to or greater than the threshold and transmitted to the communication apparatus from the server apparatus, a period of time from time at which the second packet is acquired to time at which an acknowledgement packet transmitted in response to the second packet is acquired, and the round-trip time.

Abstract: An information processing apparatus receives a request transmitted from a client to a server and a response transmitted from the server to the client. The information processing apparatus includes a processor. The processor counts a first number of first requests having no corresponding response within a first time period, counts a second number of second requests having a corresponding response, and detects a failure in the server on the basis of the first number and the second number.
