Hi,

How can i gracefully shutdown Logstash without losing any events that it might still be processing?

Basically what i want is to stop the `input` from processing and then wait until all events that are already under way to finish processing and only then terminate the process.

Is the the flow that happens today when i run `service Logstash stop`? And what about when Logstash receives a SIGTERM signal?

Yes, as of Logstash 1.5 that's how things work.

> And what about when Logstash receives a SIGTERM signal?

`service logstash stop` sends SIGTERM.

Great to hear.

And is there a timeout that if Logstash doesn't finish by that timeout it will kill it? Or it just waits forever?

No such timeout is documented so I'd assume there is none.
