The Tracer shows the SOAP messages, the respective SOAP message requests
and responses - when the services are deployed on the server, and the invoked
operations. By default, this feature is turned off. You have to turn it on to
enable tracing.
Warning: Turning on the Tracer feature will have a drag
on the performance. This is because all the SOAP messages will always be
completely built (i.e., deferred building will not be done) and stored in the
database by WSO2 Data Services. Hence this option should be used with
caution.
Figure 1: Turned OFF SOAP Tracer
In the navigator, under Monitor, click SOAP Message
Tracer. The SOAP Message Tracer page
appears.
In the Status field, click On.
The tracer will show the messages of the operations that were
invoked.
By using the SOAP tracer, you can see the SOAP messages with their
time-stamps, service name, operation invoked and the number of requests to
the server. The most recent SOAP messages are listed on the top. When a
particular SOAP message is selected, its request and the response can be
viewed.
Note: This tracer does not apply to operations invoked in
the admin services, as they are filtered out.
