[gt-user] Search and log wsrf-service activities??

[King Khan]

Hi @ all,
I am newbie to GT4, I want to develop a GT4 service that:

first: searches the required GT4 service, suppose ServiceA.
second: monitors the required service (ServiceA) and log its invokation plus
data communicated.

Any suggestions/idea on what technology to use and what part of GT4 to use??

Thanks in advance.
K.
