Hi All,
Thanks again for all your support in the Nagios Forums,

I am wondering if there is a way to show HOST Down if no Traps received on any Service.

Here is my config:
-> HOST
--> SERVICETEMPLATE (75 Services, 1 Service per OID and mapped in snmptt)

Below is an example of 1 Service Template:

Code: Select all

define service {
       name                                     upsFailureNotify_service
       host_name                                *
       hostgroup_name                           host
       service_description                      upsFailureNotify SNMP Traps
       servicegroups                            upsFailureNotify_servicegroup
       check_command                            check_dummy!!!!!!!!
       is_volatile                              1
       initial_state                            o
       max_check_attempts                       1
       check_interval                           1
       retry_interval                           1
       active_checks_enabled                    0
       passive_checks_enabled                   1
       check_period                             xi_timeperiod_24x7
       flap_detection_enabled                   0
       notification_interval                    1
       notification_period                      xi_timeperiod_24x7
       notification_options                     w,c,u,r,
       notifications_enabled                    1
       contacts                                 nagiosadmin
       contact_groups                           admins
       icon_image                               snmptrap.png
       register                                 0

}

Now Imagine having 75 of these services per Host, what I need to accomplish is if NONE of the Services has any DATA trigger Freshness which will trigger check_dummy!2!"No SNMP TRAP, possible issue"!!!!!!.

Now I can do this with specific Services which I have done already but sometimes a specific service might not be triggered all the time on all the hosts but we constantly receive random Traps on all hosts and wondering if I could execute HOST Down if no Service Traps received. The Services are set up as Service Templates to minimize duplication.

Any help would be greatly appreciated,
Sincerely,
Michael

You could try to use the check_cluster check as a host check to validate the state of each service under the host. Otherwise I honestly cannot think of a default way to do it, without lots of external scripting.

We can close this thread as I will be investing further as per your comments.
