team!

I’ve got an issue when i try to start my container with logstash.

[2024-06-25T13:53:08,047][INFO ][logstash.inputs.udp      ][main][ff352f2ccd0c89446b4546db6aa5ac501122eaef1754ce7230f4b66abd160420] Starting UDP listener {:address=>"sa27-vm-log-elk1.sam.loc:5044"}

[root@sa27-vm-log-elk1 elk]#

Here is my logstash.conf

input {
  udp {
    host => "0.0.0.0"
    port => 5044
  }
}

filter {}

output {
  elasticsearch {
    index => "logstash-%{+YYYY.MM.dd}"
    hosts => ["http://es01:9200"]
    user => "elastic"
    password => "elastic1"
    #ssl_enabled => true
   # cacert => "/usr/share/logstash/certs/ca/ca.crt"
  }
  #stdout {}
}

And logstash.yml:

http.host: "0.0.0.0"
xpack.monitoring.elasticsearch.hosts: [ "http://es01:9200" ]

Service in docker-compose file:

 logstash:
   image: logstash:${STACK_VERSION}
   labels:
     co.elastic.logs/module: logstash
   user: root
   volumes:
     - logstashdata01:/usr/share/logstash/data
     - ./logstash/logstash.conf:/usr/local/data/elk/logstash/logstash.conf
   environment:
     - xpack.security.enabled=false
     - xpack.security.http.ssl.enabled=false
     - NODE_NAME="logstash"
     - xpack.monitoring.enabled=false
     - ELASTIC_USER=elastic
     - ELASTIC_PASSWORD=${ELASTIC_PASSWORD}
     - ELASTIC_HOSTS=http://es01:9200
   command: logstash -f /usr/local/data/elk/logstash/logstash.conf
   ports:
     - "5044:5044/udp"
   mem_limit: ${LS_MEM_LIMIT}

I understand that i miss or write wrong anything in block input in logstash.conf, but i can’t understand what i do wrong.

I tried search information about this problem, but in internet another faults.
Can you help me?
