title: Zabbix Trapper: Cannot get data from orabbix
body: <p>I am using orabbix to monitor my db. The data from the queries executed on this db using orabbix are sent to zabbix server. However, I am not able to see the data reaching zabbix.</p>
  
  <p>On my zabbix web console, I see this message on the triggers added - "Trigger expression updated. No status update so far."</p>
  
  <p>Any ideas?</p>
  
  <p>My update interval for the trigger is set to 30 sec. </p>
