measure execution time using interceptors

Question

I am intercepting wcf calls of services I host in my application in order to display data about the service (how many calls each method handled, log the methods parameters etc`). In addition to that, I want to measure the execution time of each method.

I am already wrapping the instance with Castle interceptor, and I use StopWatch to measure the sync methods.

However, I can not use stopwatch on async method because I have 2 different methods (for beginInvoke and EndInvoke, I intercept the WCF invoker).

How can I measure the execution time, or at least relate the invocations of Begin and End?

Thanks

It's sounds like this question was already answered here Using the Stopwatch with Async methods

Maybe I wasn't clear so I improved my question. Thanks – Tomer K Dec 03 '14 at 07:20

Got it,

I realized that the invocation.ReturnValue holds the task so all I had to do is Implementing a TaskInterceptor :

public class TaskInterceptor : IInterceptor
{
    public void Intercept(IInvocation invocation)
    {
        var task = invocation.ReturnValue as Task;

        InterceptBeforeInvoking();

        invocation.Proceed();

        task.ContinueWith(InterceptAfterInvocation);


    }

    private void InterceptAfterInvocation(Task obj)
    {


    }

    private void InterceptBeforeInvoking()
    {


    }
}
