INFORMATION PROCESSING APPARATUS AND METHOD FOR DETERMINING TIME CORRECTION VALUES

摘要

A first memory stores requester event records describing events that occurred in relation to processes executed in a first server. A second memory stores requestee event records describing events that occurred in relation to processes executed in a second server in response to execution requests issued from the first server. An associating unit searches the first and second memories for requester event records and requestee event records whose transaction identifiers are identical and associates the found records together. A determining unit compares the associated event records with each other in terms of their time information. Based on this comparison, the determining unit determines a correction value for correcting time differences between requester event records in the first memory and requestee event records in the second memory.

1. An information processing apparatus comprising
a memory configured to store:
requester event records describing events that occurred in relation to processes executed in a first server as part of transactions, the requester event records each including time information indicating occurrence time of an event and a transaction identifier indicating a transaction that invoked that event, andrequestee event records describing events that occurred in relation to processes executed in a second server in response to execution requests issued from the first server as part of the transactions, the requestee event records each including time information indicating occurrence time of an event in the second server and a transaction identifier indicating a transaction that invoked that event; and a processor configured to perform a process including: searching the memory to find requester event records and requestee event records whose transaction identifiers are identical and associating the found requester event records with the found requestee event records, comparing the associated requester event records and requestee event records with each other in terms of the time information thereof, and determining a correction value for correcting time differences between the time information of the requester event records and the time information of the requestee event records, based on a result of the comparing.
