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.

Abstract: The system of the present invention gives a load to a computer system according to load parameter specification from a system administrator, measures a response and a throughput while giving the load to the computer system, then measures a resource situation of each resource while the load is given. Then, it determines load monitoring conditions relating to a monitoring point, a monitoring item and a threshold from results of measuring the response and throughput and the results of measuring the resource situation and performs load monitoring on the determined load monitoring conditions.
