Document Type and Number:
Japanese Patent JP2020135701
Kind Code:
A
Abstract:
To reduce a communication load in log collection.SOLUTION: An information processing device 10 acquires log information L1, L2 from log acquisition target devices 20, 30, extracts difference between the log information L1 and L2 as a variable part, replaces the variable part with an identifier, and calculates a first hash value of log information after replacement. The information processing device 10 transmits extraction information used for extraction of the variable part, the identifier, and the first hash value to a log acquisition target device 40. The log acquisition target device 40 receives the extraction information, the identifier, and the first hash value, extracts the variable part from log information L3 based on the extraction information, and calculates a second hash value of log information after replacement of replacing the variable part of the log information L3 with the identifier. The log acquisition target device 40 determines whether the second hash value and the first hash value match each other, transmits the first hash value to the information processing device 10 if they match, and transmits the log information 3 to the information processing device 10 if they do not match.SELECTED DRAWING: Figure 1
