MONITORING SYSTEM AND METHOD FOR MONITORING
Document Type and Number:
WIPO Patent Application WO/2017/037801
Kind Code:
A1
Abstract:
Provided is a monitoring system having: a monitoring object selection unit for generating a distributed representation of events included in a first log that is a set of events which include a time of day and a message and that is outputted from a system being monitored, calculating, as pertains to the distributed representation of a set of two kinds of events, a first correlation value of an event pair the times of day of which are within a prescribed time, selecting a first log pair that corresponds to the first correlation value greater than or equal to a prescribed value, and generating a function for extracting an event to be monitored from an event set included in first logs that constitute the first log pair; and a monitoring unit for using the function to extract an event to be monitored from an event set included in second logs that are outputted from the system being monitored while the system is operating and that constitute a second log pair that corresponds to the selected first log pair, calculating a second correlation value of the extracted event pair, and detecting a change from the first correlation value to the second correlation value.
