Add new input plugin when logstash is running

Does logstash have any way for user to add new input plugin when it is running?
For instance, I'm just monitoring fileA, now I want to monitor fileB and a database also, but I don't want to shut down or restart logstash. how can I do?


Logstash does not support on the fly configuration changes. The closest you can get with the file input is using a wide filename pattern in your configuration and then creating a new logfile that matches that pattern. Such a file will be picked up within a few seconds.

thanks very much. it may be an another way to solve my problem.
