SYSTEM OPERATION TRACING METHOD ON DISTRIBUTED SYSTEM

摘要

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.

1. A log management method for commonly managing a log data generated in a plurality of systems, the method comprising:
a log output step whereby a processing node coupled to the system outputs a log by writing information regarding processing at the processing node to header information; a log acquisition step of acquiring the log from the processing node; a reference step of referring to information concerning the processing from the header information of a plurality of the logs acquired thereof; and an order determination step of determining order of the plurality of logs in accordance with the information referred thereof regarding the processing.
