Elastic Stack Logstash

Hello Team,

I am getting unrecognised SSL error when i use elasticsearch output pipeline in my logstash located in different machine.
I am using another logstash in my elasticsearch machine and it is indexing data properly.

below is the error when i try to input either file or direct TCP ,

Below is my Logstash Conf file

    input {
      file {
       path => "/tmp/DARP-intel-output.json"
       codec => "json"
     }
    }
    output {
      elasticsearch {
        hosts => "https://192.168.56.10:9200"
        index => "threat-intel-%{+YYYY.MM.dd}"
      }
    }

Also I tried another type of Input but still same error.

input {
 tcp {
  port => 5514
  }
}
filter {
  # Tag minemeld events
  if "@origin" in [message] {
    mutate {
      add_tag => "minemeld"
    }
    json {
      source => "message"
    }
  }
}
output {
  elasticsearch {
    hosts => "https://192.168.56.10:9200"
    index => "threat-intel-%{+YYYY.MM.dd}"
    cacert => "/etc/nginx/minemeld.cer"
  }
}

This logstash is 6.7 and elasticsearch in other machine is 6.6.2 .

Kindly help me with troubleshooting this error.

Hi All,

I fixed the issue . It was a simple mistake which confused so much.

I used http in output plugin instead of https.

my final config

input {
 tcp {
  port => 5514
  }
}
filter {
  # Tag minemeld events
  if "@origin" in [message] {
    mutate {
      add_tag => "minemeld"
    }
    json {
      source => "message"
    }
  }
}
output {
  elasticsearch {
    hosts => "http://192.168.56.10:9200"
    index => "logstash-threat-intel-%{+YYYY.MM.dd}"
    cacert => "/etc/nginx/minemeld.cer"
  }
}
