Access log analyzer and access log analyzing method
First Claim
1. An access log analyzing method comprising the steps of:
- acquiring an access log from a server to be analyzed;
totaling the acquired data for each monitored item;
diagnosing an access status of the server based on the totaled data; and
providing the result of diagnosis to a requester of the analysis;
whereinthe diagnosing step includes a step of calculating an amount of variation in target data based on the statistic of data within a predetermined period of time for the monitored item, and a step of creating a diagnostic statement with reference to a diagnostic table defining a model of a corresponding diagnostic statement when a significant variation is detected by the step of calculating the amount of the variation in the target data.

Abstract
An access log analyzer extracts significant information from an enormous amount of data of access logs of a Web server so as to appropriately display the result of analysis. The access log analyzer includes an FTP module for acquiring a log from a server to be analyzed, a pre-formatting module for pre-processing the acquired log, a pre-counting module for totaling preformatted data for each monitored item, a main diagnostic statement creating module for creating a main diagnostic statement for the monitored item of the pre-counted data, a sub-diagnostic statement creating module for creating a sub-diagnostic statement for data related to the main diagnostic statement, a diagnostic statement connecting module for connecting the diagnostic statements, and a dispatcher module for managing the execution of each of the modules. The diagnostic statement creating modules have the functions of calculating a Z value for a diagnosed item and then generating a diagnostic statement in a natural language if there is a variation larger than usual with reference to a diagnostic parameter describing a model of a diagnostic statement corresponding to the range of the Z value.
