CPU usage performance problem

[alejandrobarrios07]

When I use the plugin the CPU reaches 100 percent. The MongoDB database has approximately 500,000 documents in the collection. The configuration I have is the following:

input {
  mongodb {
    uri => 'mongodb://User:Password@xxx.xxx.xxx.xxx:27017/production?ssl=false'
    placeholder_db_dir => '/opt/logstash-mongodb/'
    placeholder_db_name => 'logstash_sqlite.db'
    collection => 'col_info'
    generateId => true
    batch_size => 30
    tags => "mongodb"
  }
}

filter {
  if "mongodb" in [tags] {
    mutate{
      rename => ["_id", "Obj_id"]
      convert => { "phone_number" => "string" }
    }
  }
}

output {
  if "mongodb" in [tags] {
    elasticsearch {
      index => "db-mongodb-%{+YYYY.MM}"
      document_id => "%{Obj_id}"
      hosts => "localhost:9200"
    }
  }
}

What could be the problem?
