Re: [aspectj-users] How to weave the method calls inside an war file?

[Eric B <ebenzacar@xxxxxxxxx>]

What logging platform are you using?

If you are using Log4j, you can use the MappedDiagnosticContext (MDC) class https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/MDC.html.  This is managed on a per-thread basis, so you can assign an ID in the MDC as part of a request listener, and any Log4j call that is made in that thread will have access to the id stored in the MDC.  This allows you to recall the id in a logging statement.

All logs will still be pushed to the same appender, however you would then be able to sort and/or filter based on the ID.  If memory serves, retrieving the variable for the appender is done via the %X{VarName}.

I also believe that Logback has a similar MDC functionality.

Thanks,

Eric

I have few questions on this specific task; Now I have written by monitoring
logic in the aspectj. It works so smoothly and tested in tomcat and other
servers as well.

I was wondering, if this can be done as well:

1. The logging gets started when I turn on few params on my aspectj jar,
which starts logging.
2. So if possible, when it logs, can I make it to log according to each
thread level?

What I was thinking over here is this, I will start my logging param in
aspectj, so imagine, when two users access the webpage in the server, now I
want the trace should be completely isolated from each of the request. I
know HTTP doesn't have states, we can do this in sort of attaching some
"sessionID" to each trace, and then do a batch operation for getting the
result of each thread; so that trace "flow" is perfect.

I just want to know if there are any other ways of doing this?

Your thoughts will be really helpful to me.
