Log management apparatus, computer-readable recording medium having stored therein log management program, and log management method

A log management apparatus comprising

• a processor that
• obtains a normal log item group from each of a plurality of logs, the plurality of logs being outputted from a plurality of monitoring targets, respectively, each of the normal log item groups being outputted from a corresponding monitoring target in one cycle of a regular process of the corresponding monitoring target,
• detects a first log item group from a first log, the first log item group being different from the normal log item group obtained from the first log,
• specifies a second log item group from a second log related to the first log, the second log item group being outputted in a same period as that of the first log item group,
• extracts the first log item group from the first log, and outputs the first log item group, and
• extracts the specified second log item group from the second log, and outputs the second log item group.

A log management method in an information processing apparatus that manages a plurality of logs outputted from a plurality of monitoring targets, respectively, the log management method comprising:

• at a processor of the information processing apparatus,
• obtaining a normal log item group from each of the plurality of logs, each of the normal log item groups being outputted from a corresponding monitoring target in one cycle of a regular process of the corresponding monitoring target;
• detecting a first log item group from a first log, the first log item group being different from the normal log item group obtained from the first log;
• specifying a second log item group from a second log related to the first log, the second log item group being outputted in a same period as that of the first log item group;
• extracting the first log item group from the first log, and outputting the first log item group;
• and
• extracting the specified second log item group from the second log, and outputting the second log item group.
