> We can confirm the stack trace of node when we access the node's web interface "/stacks".
> And the stack trace is output not only browser but also log file of node.
> Considering the cluster's management policy (e.g. log monitoring), it should be controllable.
> At now implementation, stack trace output controls HttpServer class.
> If we change log level, other messages does not output by HttpServer class.
> So, we control to output the stacktrace to log file.
