Error message

I am encountering an issue with establishing a connection from Logstash to my local Elasticsearch instance. Each time I attempt to send data from Logstash to Elasticsearch, I receive the following error messages:

[logstash.outputs.elasticsearch][main] Failed to perform request {:message=>"Connect to localhost:9200 [localhost/127.0.0.1] failed: Connection refused (Connection refused)", :exception=>Manticore::SocketException, :cause=>org.apache.http.conn.HttpHostConnectException: Connect to localhost:9200 [localhost/127.0.0.1] failed: Connection refused (Connection refused)}

here is my logstash.conf

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input {
  file {
    path => "/usr/share/logstash/config/test.csv"
    start_position => "beginning"
    sincedb_path => "/dev/null"  
   

  }
  }

filter {

    separator => ";"
    columns => ["aa","bb","cc"]
  }

}

Your ES is not up and running or it's blocked.
Check:

ES service: systemctl status elasticsearch
network.host: 0.0.0.0 in elasticsearch.yml
setings in output elasticsearch should be on v8:

output {
  elasticsearch {
    hosts => ["https://localhost:9200"]
    data_stream => true
    user => "elastic"
    password => "password"
    ssl_enabled => true
    ssl_verification_mode => none
  }
}

You can set indexname by index => "name" or set datastream params

when i write with curl - x post it works , but with logstash no ....

leandrojmp · April 23, 2024, 2:35pm

What version of Logstash are you using? You didn't specify, so people will assume that you are using a recent version.

The setting ssl_verification_mode is available since 8.9 if I'm not wrong, if you are using an older version you need to use the correct setting name, you can check what is here.

samsu · April 23, 2024, 2:41pm

i use the 8.0.0 version now

samsu · April 23, 2024, 2:50pm

I have commented out the ssl_verification_mode setting in my Logstash configuration file.

Check the file again, it is still using it, also you need to use the correct name of the setting for your version, check the linked documentation the previous answer.

You need to use:

ssl => true
ssl_certificate_verification => true
cacert => "/path/to/ca.pem"

Everyone should use 8.x, and I don't see why not the latest version.
