Well, I have this above error and I don't know how to fix it.

My config:

input {
  file {
    path => "/opt/nsm/*"
    start_position => "beginning"
    sincedb_path => "/dev/null"
  }
}

output {
  elasticsearch {
    hosts => ["http://192.168.0.108:9200"]
    index => "%{[@metadata][nsm]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "****************"
  }
}

I fixed it with this:

output {
elasticsearch {
hosts => ["https://192.168.0.108:9200"]
index => "%{[@metadata][nsm]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
user => "elastic"
password => "****************"
ssl_certificate_verification => false
}
}
