Abstract: A test support device includes a processor configured to acquire event information on events which occur during an execution of a target program. The processor is configured to classify the events into event groups on basis of similarity of timings at which the respective events occur. The processor is configured to calculate, for each of the event groups, a summed value of evaluation values of the respective events classified into the relevant event group. The processor is configured to determine for each of the event groups, on basis of the summed value, whether a breakpoint of a target process executed by the target program is present at a timing corresponding to the relevant event group. The processor is configured to display timing information indicating a timing at which a breakpoint is determined to be present, in association with elapsed time after a start of executing the target program.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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. When the request telegraphic message is received, trace collection units decide whether trace collection is to be made or not based on the trace collection condition of the relay code, in other words, based on the switch information which indicates whether trace collection is to be made or not to perform a process. The trace collection condition includes a function ID which indicates a range of tracing for each application and a relay ID which records applications which has been passed through.
