Which Serilog sink to use for sending to Logstash?

I received a suggestion from Nicholas Blumhardt (Serilog creator) to use RollingFileSink with JsonFormatter.

The accepted answer was written before the sink Serilog.Sinks.Http existed.

Instead of logging to file and having Filebeat monitoring it, one could have the HTTP sink post log events to the Logstash HTTP input plugin. This would mean fewer moving parts on the instances where the logs where created.
