Nagios Support Forum

Hi,

I am trying to monitor a linux server using Nagios Core. I have been able to receive the normal service alerts but failed to receive SNMP Trap alerts. Also, I can view the received traps in /var/log/messages as well as in /var/log/snmptt/snmptt.log. But the service TRAP is not turning to the WARNING state as it should be after receiving a trap.

I am in dire need of some help.

My services.cfg looks like this:

define service {
use generic-service
register 0
check_period 24x7
max_check_attempts 1
normal_check_interval 15
retry_check_interval 5
active_checks_enabled 1
passive_checks_enabled 1
parallelize_check 1
obsess_over_service 1
check_freshness 0
flap_detection_enabled 1
process_perf_data 1
retain_status_information 1
retain_nonstatus_information 1
notification_interval 315360000
notification_period 24x7
notification_options w,u,c,r
notifications_enabled 1
event_handler_enabled 1
is_volatile 1
}


define service {
use generic-service
name snmptrap-service1
register 0
service_description TRAP
is_volatile 1
check_command check-host-alive
flap_detection_enabled 0
process_perf_data 0
max_check_attempts 1
normal_check_interval 1
retry_check_interval 1
retry_check_interval 1
passive_checks_enabled 1
check_period 24x7
notification_interval 315360000
}

define service{
use snmptrap-service1
host_name XYZ
service_description TRAP
contact_groups admins
}

My hosts.cfg :

## Default Linux Host Template ##
define host{
name linux-box1 ; Name of this template
use generic-host ; Inherit default values
check_period 24x7
check_interval 5
retry_interval 1
max_check_attempts 10
check_command check-host-alive
notification_period 24x7
notification_interval 30
notification_options d,r
contact_groups admins
register 0 ; DONT REGISTER THIS - ITS A TEMPLATE
}

## Default
define host{
use linux-box1 ; Inherit default values
host_name XYZ ; The name we are giving to this server
alias xyz
address xxx.xxx.xxx.xxx
passive_checks_enabled 1
}

Please any help to fix this would be appreciated. I cannot figure out where I am going wrong.
Thanks so much.

If the traps are hitting the /var/log/snmp/snmptt.log then it is recognizing them.

Are the events being recorded in /usr/local/nagios/var/nagios.log ?

You might need to enable log_passive_checks=1 in nagios.cfg to get some more detail as to what is going on.

Could you also provide the output from 'grep -i snmptrap /var/log/messages' ?

Thanks Troy and Rob! @debbie_d890, please let us know when you've got that information, thanks!
