System, method, program, and system implementation method for transaction process logging

摘要

A system is provided to log a transaction process performed based on a service level agreement concerning the response time of the transaction process. The system includes a logging policy table, a transaction process monitoring unit, and a storage device. The logging policy table records one or more logging policies defined to log a transaction process with a varying amount of log data based on a required response time specified in the service level agreement. The transaction process monitoring unit automatically monitors the response time of the transaction process. The storage device records a transaction process log. The system further includes a logging control unit. The logging control unit uses response time of a transaction process monitored by the transaction process monitoring unit to select one of the logging policies stored in the logging policy table. According to the selected logging policy, the logging control unit allows the storage device to record a log of the transaction process.
