How to change from filebeat-* to logstash-*

I used filebeat and logstash before, but now I just want to use pure logstash, how do I change from one to another? i.e. in discover section of kibana, I wanna see logstash-* instead of filebeat-*, is there a way to do that? I imagine that if I use 'file' in logstash input instead of 'beats' I don't need filebeat anymore.

In Kibana management, create an index pattern for logstash-* in any spaces.
