Abstract
Abstract A collection filter is created by a filter creation module according to instruction from a trace control module, and packet logs are collected by a line collection module. Further, an application log extraction module extracts application logs from packet logs by sequence matching using an extraction filter which contains a sequence filter, a performance analysis module analyzes the application logs using an analysis filter, and a graph display module displays a graph of the results.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
189 words
A transaction tracing apparatus for a computer network having a plurality of units connected via a transfer path, wherein transactions are processed by exchange of transmission information using a conversational format of request and reply between at least two units, said transaction tracing apparatus comprising: a trace control module which controls the transaction tracing apparatus based on a trace instruction file having a log file name, a filter file name, and analysis instructions having corresponding specification information; a filter creation module which creates an extraction filter and an analysis filter used in the extraction of a particular conversation sequence from a packet log; a line collection module which collects transmission information from said transfer path thereby creating a transmission log; an application log extraction module which extracts from the transmission log an application log of the particular conversation sequence specified by the extraction filter; a performance analysis module which extracts the particular conversation sequence, specified by the analysis filter, from said application log, and analyzes the transaction producing an analysis result; and a graph display module which displays graphs based on the analysis results of said performance analysis module.
Claim 2
Dependent Claim
