A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process including executing one of a plurality of programs, acquiring a status of variation in an internal state of a memory occurred in response to the executing, determining whether a specified status pattern is stored in a storage device that stores a plurality of status patterns of variation in an internal state of the memory, the specified status pattern satisfying a predetermined criterion regarding a similarity with the acquired status, when the specified status pattern is stored in the storage device, generating a test scenario that is a combination of programs including the executed program, and when the specified status pattern is not stored in the storage device, suppressing the generating the test scenario.

Non-transitory computer-readable storage medium, generation method, and information processing apparatus

A performance data collection unit collects the performance data of managed CPUs from a performance measurement unit. A grouping unit compares the collected performance data with each other, forms groups of CPUs whose performance data is approximate to each other, and selects a representative CPU of each group. A performance data transmission unit transmits the collected performance data to a performance data management apparatus that accumulates and manages the performance data. In this connection, the performance data of the representative CPUs of the groups is transmitted at specified transmission intervals, and the performance data of the other CPUs of the groups is transmitted at transmission intervals that are longer than the specified transmission intervals.

Method and apparatus for collecting performance data, and system for managing performance data

An analysis method for carrying out an analysis for responses of a computer system including a plurality of servers, includes: obtaining data concerning a CPU utilization ratio of each of the plurality of servers from the computer system, and storing the data concerning the CPU utilization ratio into a CPU utilization ratio storage; obtaining processing history data generated in the computer system, generating data of a request frequency by users of the computer system, and storing the processing history data into a request frequency data storage; and estimating an average delay time in each server by using the CPU utilization ratio of each server, which is stored in the CPU utilization ratio storage, and the request frequency stored in the request frequency data storage, and storing the estimated average delay time into a server delay time storage. By carrying out such a processing, the analysis can be carried out without changing the computer system to be analyzed and any additional cost.

Analysis method and apparatus

A distributed application system has a plurality of applications running on a plurality of servers arranged hierarchically and, when receiving a request telegraphic message from a client, executes processes while transferring a relay code between applications in order. A trace condition embedding unit embeds a trace collection condition into a relay code and transfers it to the next application. Trace collection units decide whether trace collection is to be made or not, and perform a process. The trace collection condition includes an indication of a range of tracing for each application and a record of applications which has passed through. The trace condition embedding unit further includes intermittent switch information which indicates a ratio of trace collection to reception times of the request telegraphic message.

Trace processing program, method and system

An apparatus for displaying system management information includes a combination storing unit that stores display pattern information that is obtained by combining, in subjective basis, system management information provided by a plurality of system management units; and a combination display unit that combines the system management information based on the display pattern stored in the combination storing unit, and displays the system management information combined.
