Abstract:
1. A failure detection method to detect failures of an information processing device coupled to a plurality of computers based on a plurality of types of messages output by the information processing device, the failure detection method comprising: transmitting, by the information processing device, one or more first messages to a first computer among the plurality of computers and transmitting one or more second messages to a second computer among the plurality of computers, each type of the one or more first messages belonging to a first group and each type of the one or more second messages belonging to a second group different from the first group; generating, by the first computer, first failure candidate information including information of the each type of the one or more first messages, and transmitting the first failure candidate information to a third computer; generating, by the second computer, second failure candidate information including information of the each type of the one or more second messages, and transmitting the second failure candidate information to the third computer; and detecting, by the third computer, the failure of the information processing device based on the first failure candidate information and the second failure candidate information, wherein the plurality of types are divided into a plurality of groups of which elements do not overlap, the plurality of groups including the first group and the second group, with a computer having been assigned to each of the plurality of types as a collection destination.
