RE: [aspectj-users] Performancemonitoring aspect

["Conway. Fintan (IT Solutions)" <Fintan.Conway@xxxxxx>]

How about :

@Aspect
MyAspect{
    private long start;
    private long end;
    private long duration;

    @Before("call (* Customer.updateCustomer(..)"
    public startTimer(){
        start = System.getCurrentTimeMillis();
    }

    @After("call (* CustomerDao.save(..)"
    public stopTimer(){
        end = System.getCurrentTimeMillis();
        duration = end - start;
	  log("Time to save Customer :  " + duration);
    }
}

HTH,

Fintan

Hi.

i was just wandering if there could be a clever way of making an aspect
that could figure out the duration in time from a call in one class to a
later call in another class ?

To elaborate a little.
Let say we have a class called Customer who has a method,
updateCustomer() And then we have a class CustomerDao with a method
save() In addition we have a unspecified number of logical application
layers, doing alot of things as a part of this process, some of them
e.g. checking the given adress on a central adress register and so on.

So what i would like to is to start a timer when someone calls
updateCustomer(), then let the applicationflow go about it's ususal
tasks, some of them asynchroniously and some not, until we get to the
point that the dao is finished with the persisting in the database, then
i would like to stop the timer handle and log the result. Ideas anyone ?

@Aspect
MyAspect{
    private Timer timer = new Timer();

    @Before("call (* Customer.updateCustomer(..)"
    public startTimer(){
        timer.start();
    }

    @After("call (* CustomerDao.save(..)"
    public stopTimer(){
        timer.stop();
        timer.log();
    }
}


Best regards
