Diagnostic Sample(Trace Logs)

Question

I have configured Tracing Logs for both web and worker roles (performance counters and errors). Also, I have created the log for the error using unhandled exception handler, but that is still not handled and application terminates as we are explicitly throwing an error. To handle the error, we have to first recognize it from the log and only then we can handle it I

What do i want in real scenario?? Below Mansion..


we have  consume 3 Web service in single worker role. And each Web service is Independence to each other. suppose that 2nd webservice is failed due to some exception occurring , so i want to use application handler to handle the exception for what and where s exception  occurring and we can maintain our error logs  . also want  my 3 service is continue execute without care of second service  failed .
