Error while connecting to Amazon Elasticsearch

[rupini]

Hi,

I am a beginner and trying to figure our ELK. I have logstash configured in an AWS EC2 instance. I am trying to transfer the data from S3 bucket to AWS ES service using logstash. I am getting the following error when I run logstash.

WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults
Could not find log4j2 configuration at path /usr/share/logstash/config/log4j2.properties. Using default config which logs errors to the console

Below is my config file

input {

     access_key_id => ""
     secret_access_key => ""
     region => "us-east-2"
     bucket => "s3-XXXXX"
     prefix => "logs"
     #interval => "10"
     #additional_settings => {
      #force_path_style => true
      #follow_redirects => false}
  }
}
 
output {
	amazon_es {
    hosts => ["https://search-cyberdemo-xxxxxxxxxxxxxxx.us-east-2.es.amazonaws.com"]
	region => "us-east-2"
    index => "logs-%{+YYYY.MM.dd}"
	ssl => true
	    
  }
}

Thanks in advance
