I want to run multiple conf file. I tried

  1. logstash -f 1.conf, 2.conf
  2. I tried to run multiple instance of logstash separately

Not sure what options can use
Sorry for duplicate / re-post. But still no definite answers any where in the forum..

I was able to resolve it by copying multiple conf into the same folder. Thank you
