currently,,I want to send nginx_access.log and nginx_error.log to logstash server.here is the filebeat.yml configuration,I don't know whether I am right or not.
and this is the nginx_access log format:

eeeeee.............I don't know how to configure logstash.conf in logstash server,to separate them and treat different logs in different ways.

this configuration above is the wrong my example ....I searched a lot,still don't get a clue.
appreciate a lot ,if you could help
