Performance monitoring method in a distributed processing system

A computer system comprising:

• a manager to be connected to computers via a network and having a display device,
• each of said computers executing a program entity in a processing group communicating with another program entity in said group executed on another computer,
• wherein each of said computers sends to said manager performance data including relation information to another program entity in the group of processing and at least one of a receive time of message from said another program entity and a send time of message to said another program entity for said program entity when communication between the program entity and said another program entity occurs, and
• wherein said manager receives the performance data from each computer, associates the performance data between program entities on the basis of the relation information, calculates processing time of each of the program entities and communication time between program entities on the basis of the associated performance data, and displays on the display device the calculated processing time of each associated program entity and the calculated communication time between the associated program entities in a time series manner according to a processing order.

A computer-readable storage medium having stored thereon a program for performing a performance monitoring method of a distributed processing system in which several program entities in a processing group are distributed and arranged on several computers, and the program entities execute processing by communicating with the other program entities, the method performed by the program comprising the steps of:

• for a first program entity, collecting performance data including relation information to a second program entity in the processing group and at least one of a receive time of message from the second program entity and a send time of message to the second program entity for a program entity;
• associating the performance data between the program entities on the basis of the relation information;
• calculating processing time of each of the program entities and communication time between program entities on the basis of the associated performance data;
• and
• displaying the calculated processing time of each program entity and the calculated communication time between associated program entities in a time series manner according to an order of processing.
