This subsection gives an example to describe how to investigate whether the request received by a Web server from a client is processed on an application server.

In the following figure, from the trace based performance analysis files collected on the Web server you will understand that the request is received on 2004/2/5 16:32:31.

Figure 7-11 Example of the trace based performance analysis file collected in the Web server

You use the root application information of this request as a key to investigate trace based performance analysis files collected on Application Server.

The following figure shows an example of filtering the trace based performance analysis files collected in Application Server with RootAP IP:10.209.13.123, RootAP ID:2200, and RootAP CommNo.:0x00000000000000c7 as keys.

Figure 7-12 Example of the filtered trace based performance analysis file collected in Application Server

In this way, if you filter the trace based performance analysis files collected on an application server with a root application information as a key, you can investigate the processing of a series of requests in an application server.
