Adrian hi,

Thanks for the reply can you please show me how to incorporate the below
into my below statement ?

SELECT 		 a.eventuei AS _eventuei,
                 a.nodeid AS _nodeid,
                 a.ipaddr AS _ipaddr,
                 now() AS _ts
                 FROM events a
                 WHERE
eventuei='uei.opennms.org/comns/backup-success-trap' AND
(eventcreatetime > now() - interval '10 minutes')

Thanks!
Kobi
