tsm_ems --server=ICOI notify Router RouterNY25 Down 
 3rdParty DURABLE 3600 Category=3rdParty-Down Severity=2 s

The notification is for a Router named RouterNY25 and it is Down, which is in this case a durable event. The notification expires in 3600 seconds. The Category attribute of the standard notification contains the name of the event as seen in the third-party application.
