ERR Failed to publish events caused by: EOF (no tls)

Elastic Stack Beats
1

Hello,

In filebeat.log I have many :
ERR Failed to publish events caused by: EOF

I checked that my filebeat.yml is valid :
http://www.yamllint.com/

I checked that ssl is used and not tls.
I checked the logstash log : no error

It's filebeat 5.0.2.
I launched it in debug mode :`

/usr/share/filebeat/bin/filebeat -c /etc/filebeat/filebeat.yml -e -d '*'

Any idea ?

There were quite a few previous threads with similar questions. Perhaps one of these could help? https://discuss.elastic.co/search?q=ERR%20Failed%20to%20publish%20events%20caused%20by%3A%20EOF If not, please provide the filebeat and logstash config file.

Thanks Ruflin, indeed I did look at the other threads on the same subject, and ckecked for deprecated tls and ill-formated yml. But still, I couldn't resolve the problem.
So here's my filebeat.yml :

filebeat:
  prospectors:

      paths:
        - /opt/WSO2/wso2esb/repository/logs/wso2carbon.log

      ignore_older: 744h
    -
      paths:

      document_type: log

      document_type: log

         category: TECHNIQUE

output:
  logstash:
    hosts: ["elk-docker:5044"]
    ssl:
      #insecure: true
      certificate_authorities: ["/etc/pki/tls/certs/logstash-beats.crt"]
logging:

  files:
    path: /var/log/filebeat
    name: filebeat.log
    rotateeverybytes: 10485760 # = 10MB
    keepfiles: 7

And for the logstash part, 02-beats-input.conf and 30-output.conf :

input {
  beats {
    port => 5044
    ssl => true
    ssl_certificate => "/etc/pki/tls/certs/logstash-beats.crt"
    ssl_key => "/etc/pki/tls/private/logstash-beats.key"
  }
}

output {
  elasticsearch {
    hosts => ["localhost"]
    manage_template => false
    index => "filebeat-%{+YYYY.MM.dd.HH}"
    document_type => "%{[@metadata][type]}"
  }
}

which logstash version are you using? Please ensure you're using the most recent logstash-input-beats plugin.

Is it working with insecure: true?

5

As shown in previous reply with logstash conf files, 02-beats-input.conf and 30-output.conf :
No it's not it's "insecure: true", it's "ssl => true"

/opt/logstash/bin/logstash --version
logstash 5.0.2

I've been asking if events are published if insecure: true is enabled in filebeat or if you still get EOF. EOF means, the connection has been closed by remote host (saying logstash).

Also update logstash or at least the beats input plugin to most recent version.
