Is there a way to have verbose logging for my plugin but quiet logging for the rest of logstash?

I'm testing a plugin and my config

--vv across the whole of logstash is very noisy.

The only signal I want is that emanating from the @logger on my plugin.

Possible?

It'd be really handy (though possibly counter to logstash's overall goals) to have a separate file just logging these messages.

Thanks, Martin
