Anyone successfully using check extensions in recent versions? (>= 0.13.0)

Is anyone out there successfully using check extensions in recent versions of Sensu? We’ve patched our 0.13.1 deployment to allow us to run extensions in the same way we did in 0.12.x, but I can’t figure out how they’re supposed to be configured to work without those patches.

I’ve opened https://github.com/sensu/sensu/issues/866 describing what I’m trying to do, based on my understanding of the source code. This is informed by the source because there’s no official documentation on how check extensions are supposed to be configured. If we can figure out how they’re supposed to work, we need to make sure it makes it into the official docs!

Thanks,

Rich
