Trace processing program, method and system

A trace processing system for distributed applications that have a plurality of application processing units running on a plurality of servers arranged hierarchically and that, when a request telegraphic message is received from a client, executes processes for response while transferring a relay code between application processing units in order, the trace processing system comprising a controller which includes:

• a trace condition embedding unit provided to said servers receiving the request telegraphic message from said client, that when the request telegraphic message is received, embeds preset trace collection conditions including switch information that indicates whether trace collection is to be made or not in the relay code, for transfer to a next application processing unit;
• a trace collection unit that is provided in each of the application processing units provided in said plural servers and that, when the request telegraphic message is received, decides for processing whether trace collection is to be made or not based on the switch information of the trace collection conditions embedded in the relay code;
• and
• an analysis display unit that collects for analysis and display traces which have been collected by the application processing units,
• wherein the trace condition embedding unit uses as the trace collection conditions intermittent switch information that indicates a ratio of a number of times trace collection occurs, compared to a number of receptions of request telegraphic messages when trace collection is indicated by the switch information, the trace condition embedding unit embedding the trace collection conditions in the relay code in accordance with the ratio of the intermittent switch information;
• wherein the analysis display unit extracts trace information of a route in accordance with the relay ID (Identification Data) from trace information collected for each application by the trace collection unit, sorts the information in order of time and generates for display the route and relationship between applications and processes based on the result of sorting,
• wherein the analysis display unit displays a processing time from reception of the request telegraphic message to transfer to the next application such that the time corresponds to each application;
• wherein the trace condition embedding unit uses as the trace collection conditions a function ID (Identification Data) that indicates a range of trace collection for each application, and the relay ID (Identification Data), which records applications that have passed through.
