Launching a multi-file logstash config

  • bin/logstash -f PATH_TO_CONFIG_DIR/
    and

I was under the impression these should give the same output as long as the destination directory only contains .conf files. However, my trials say otherwise >> The 4th run with .conf doesn't test the configuration:

Notes:

  • ...-logstash/conf/ does only contain .conf files
