| Abstract(in English) | We proposed the efficient generating method of whitelists for log monitoring, and showed its effectiveness. However, in order to apply the method to a large-scale and highly distributed IT systems, it is necessary to perform regular expression matching process with enormous log files and whitelist at high speed. In this paper, we evaluated the 3 methods for speeding up the regular expression matching process. We applied the 3 methods to logs of real system and measured each processing time. With dividing by keyword method, we confirmed reduction of processing time for all the logs, and the greater the number of keywords, the higher the reduction effect. With the other 2 methods, we confirmed the both cases where the reduction effect could be seen or not seen depending on the log files. |
