跟踪多个系统上的用户

Question

I hava a WebApp that authenticates the users and each of their main actions are recorded in the log files.However those actions call some webservice the might call other webservices on other machines.

I would like to be able to track in the logs of those machines each user request because I am allowed to add more logs but not to change the signature of the service by adding a new field.

I was thinking to use an UUID (correlation id) and Http header to carry it.

Do you know another solution ?

Thanks

Not sure if you are using Spring, but with Spring you could intercept methods and log stuff in there, and you could do it without changing your signatures at all.
