Publication number: 20150169288Abstract: It is difficult to assign a unified index to log data accumulated and managed at individual systems with, for example, different installation ranges and times, a compliance standard, and vendors. Accordingly, it is burdensome to trace a flow of data and operations from the accumulated log data. Furthermore, if granularity of data which are output to logs differs, there is a possibility that data which can hardly be understood or are unnecessary depending on a user might be included even if all the logs are presented to the user. A log is linked to a sequence across nodes and systems by means of a combination of partial link information. Information is presented according to granularity based on the user's view, for example, on a transmitted and received data basis, application data basis, and inter-system data basis by referring to, for example, application data definition information and system configuration information.Type: ApplicationFiled: September 28, 2012Publication date: June 18, 2015Applicant: Hitachi, Ltd..Inventors: Hidenori Yamamoto, Takashi Fukumoto, Hideki Tonooka
