oracle - 试图通过logstash从oracle数据库中获取数据，但数据没有进入elasticsearch

Question

我正在尝试获取 oracle 数据库的数据，logstash但数据没有到达elasticsearch。我不确定我在哪里错过了它。我没有在logstash日志文件上看到任何错误。下面是logstashconf文件。

input {
  jdbc { 
    jdbc_validate_connection => "true" 
    jdbc_connection_string => "jdbc:oracle:thin:@//server:1521/db" 
    jdbc_user => "user" 
    jdbc_password => "pass" 
    jdbc_driver_library => "/etc/logstash/files/ojdbc7.jar" 
    jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver" 
    jdbc_paging_enabled => "true" 
    schedule => "* * * * *" 
    statement_filepath => "/etc/logstash/files/keycount.sql" 
    use_column_value => "true" 
    tracking_column => "timestamp" 
    last_run_metadata_path => "/etc/logstash/files/.logstash_jdbc_last_run"
  }
} 
output { 
  elasticsearch { 
    hosts => "localhost:9200" 
    index => "keyinventory-%{+YYYY}" 
  } 
  stdout{ 
    codec => rubydebug 
  } 
}

请有人帮助我。
