I see, I guess the only thing you need to change is the name of the loaded
plugin. Unfortunately this is being hardcoded in the java code [3].
I made a quick attempt at implementing it (it's a hack) [4] feel free to
test it.

FWIW I am currently playing with searchguard [1] and succesfully managed to
make it work with syslog-ng-3.8.1 [2]. They already have a ES 5.x branch
(haven't tested yet).


@lbudai: I guess it would make sense to modify `client-mode(transport)` to
allow for loading plugins, e.g. by adding a new option `load-plugins("Shield" "Foo" "Bar")`
