Input jdbc scheduler

Is there a specific method to running logstash with jdbc input that has a schedule? What I have noticed for the paste 1-2 hours is that my schedule is not actually running! I have the schedule set to "* * * * *" but it looks like it only runs when I close and open logstash. I tried 2 different methods 1 letting it run on ./bin/logstash -f text.conf and having it in the background with & Thanks.

@michaellizhou, mind sharing your logstash config?

Oh yeah could of totally put this on the github page. So I ran this as such

./bin/logstash -f logstash-jdbc.conf &

And I keep checking the last_start time. Its the same time as previous. Never changes!

input {
     jdbc {
        jdbc_driver_library => "/logstash-1.5.0/ojdbc7.jar"
        jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
        jdbc_connection_string => "jdbc:oracle:thin:@//"
        jdbc_user => ""
        jdbc_password => ""
        statement => "SELECT * from log where event_time > :sql_last_start"
        record_last_run => true
        last_run_metadata_path => "sincedbpath/.logstash_jdbc_last_run"
        schedule => "* * * * *"
        type => "log"
      }
    }
      date {
        locale => "en"
        timezone => "America/New_York"
        match => [
          "event_time" , "YYYY-MM-dd HH:mm:ss.SSS"
        ]
      }
    output {
    #  stdout{ codec => rubydebug}
     elasticsearch {
        host => "localhost:9200"
      }
    }
