Abstract: A method for analyzing a latency of a transaction performance is provided.

Abstract: A performance and measurement system can be used to evaluate a computing system. An operating system of the computing system produces performance data about individual processes running on the computing system. The performance data is collected and reduced by combining selected data from the performance data into standardized metrics to produce collected and reduced performance data. The collected and reduced performance data pertains to groups of the individual processes. The collected and reduced performance data is logged into at least one data file. The performance data is discarded.

Abstract: A performance and measurement system for a computing system is presented. Performance data produced by the computing system is collected and reduced before being logged. Once the data is logged, the data may be transported to a workstation and accessed by a user.In the preferred embodiment, the collected and reduced data is logged into three files. The first file is a global data file into which is logged information about the computing system as a whole. The second file is a process data file into which is logged information about selected processes. The third file is a workload data file into which is logged information about classes of processes.Information about processes are logged into the process data file when a process does something "interesting" during a specified interval. For example, a process may be considered to have done something interesting when the process is started, is terminated or uses a predetermined amount of a computing system resource during the specified interval.
