How to create a unique id for all events using logstash? This is something like incremental unique ID used in a normal database.

Is there a way to create a field with a timestamp that has six decimal place. I am worry that the lesser decimal place may result in duplicate IDs.

No, prefer the uuid filter. The fingerprint is supposed to create something that's _not_ random.
