Following is my logstash configuration,

input {  
      jdbc {
	jdbc_driver_library => "D:/ES/logstash/bin/ojdbc14.jar"
        jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
    	jdbc_connection_string => "jdbc:oracle:thin:@11.71.160.227:1521:xe"
    	jdbc_user => "kibana"
        jdbc_password => "kibana"
    	statement => "select * from info"
	schedule => "* * * * *"
    }
}

 
output {
    elasticsearch {
        hosts => "10.76.133.15:9200"
	action => "index"
        index => "ssession-%{+YYYY.MM.dd_HH:mm:ss}"
    }
    stdout { codec => rubydebug }
}

Please don't post pictures of text, they are difficult to read and some people may not be even able to see them.

@warkolm, As the output doesn't contain any error message, there is only one error message
and that is, "INFLIGHT_EVENT_COUNT".
Another error after this message shown is
mretrying failed action with response code: 503 {:level=>:warn}←[0m

The query returns records not more than 200.
