We've found that for SNMP trap services, we set the following:
is_volatile1 # notify on every failure
message, not just when going from OK to failure state
max_check_attempts1 # notify on the first failure every time
stalking_options o,w,c # log *all* OK,
Warning and Critical messages to the Nagios log even if the state hasn't changed
None of these will show all the traps in the host/service display however it
will log all the states you have defined to the log file every time the
host/service check output is received. Just a warning though - too many
hosts/services being stalked can make the log file very big.

Hi,
In past I have configured snmp traps from network devices to display in the
nagios UI. I have defined only one trap service under a network device which
captures all the traps sent for this device in the service, so it will always
show you the latest submitted trap/message and send out an alert based on if
it's a Warning/Critical trap as may be defined by you in the snmptt config file
or the integration script you used.
Since any critical/warning alert logs a ticket on a ticketing system integrated
with nagios, we are not so concerned to see all the alerts displayed in one
service.
In your case if you always want to display all the incoming traps to be
displayed permanently you may need to define multiple trap service under that
host and in the integration script you have to map different traps to the
different services which you defined. But even in that case you might have
defined and mapped a cpu trap service and a fan problem trap service under a
host, so the cpu and fan trap will not display in the same service but guess if
the new fan trap comes it will again override the old trap and show you in the
nagios UI. But in this situation there also a chance to miss a trap or unknow
trap which you may not have mapped.
The other way which we are using is I defined a single trap service under a
host and I used to reset it to OK after few seconds or minutes of the trap
submission so by default it's always OK and once a trap comes it will display
it, fire an alert and again rest to OK after few seconds.
Hope it helps you some what :)

Hi Nagios-Users,
Currently, I am working with Nagios where I have integrated it with a database
platform (remote machines) to listen to the alerts and display them in the
Nagios Web Interface.
Nagios here runs on RHEL. The remote mahine sends SNMP trap messages (its an
external device and not a box so no NRPE/SSH). I've setup SNMPTRAPD in the
machine which captures the snmp messages from the box and calls Nagios command
to route them to Nagios. For this also, I have defined a trap service to manage
the incoming traps from the remote machine.
But, the problem is that only the topmost alert is displayed in the Nagios (in
the log as well as in the Nagios Web UI). Is that like till the first one gets
cleared the other alerts for the same service don't show up? The thing is that
I need all the alerts sent from the remote machine to be sent under one
service/host to Nagios.
Any pointers regarding this will be much appreciated.
Thank You.
Regards,
Divya.
