	Subject: [Nagios-users] Multiple SNMP traps only sending one
alert
	
	

	I've set up Nagios to receive an SNMP trap from a remote source,
and it works fine.  The trap comes in, an alert is emailed out, and the
service status is set to critical.

	The problem is, subsequent traps come in and no further alerts
are emailed out (although "Last Check" reads correctly).  Here is the
service config:

	# service FAX 
	define service{ 
	        host_name               faxmachine 
	        service_description             FAX 
	        is_volatile                     1 
	        active_checks_enabled   0 
	        passive_checks_enabled  1 
	        check_period            none 
	        max_check_attempts      1 
	        normal_check_interval   2 
	        retry_check_interval    1 
	        contact_groups          mhanley 
	        notification_interval           0 
	        notification_period             24x7 
	        notification_options            c 
	        check_command           check_none 
	        } 

	What do I need to do so that I'll receive an email alert for
every trap that is sent? 

	Thanks!

The problem is your notification_interval. Set at 0, this means that
you'll never get another notification for the same status, even if a
different event causes that status. With is_volatile set, you'll get a
notification for every different SNMP trap that you get -- just set
notification_interval to something small (like 1) if you expect to get
multiple, identical traps in a row.
