nagios don't send mail for individual hosts

Hi,

It does not send mail if I only add contact_groups in host definition.

Code:

define host{
        use             generic-host        ; Inherit default values from a template
        host_name       NAME1          ; The name we're giving to this switch
        address         XX.X.X.X     ; IP address of the switch
        hostgroups      GROP1                ; Host groups this switch is associated with
         contact_groups    wadmins
        }

But If in same host-config file I add contact_groups in service definition it works.

Code:

define service{
        use                     generic-service ; Inherit values from a template
        host_name               NAME1  ; The name of the host the service is associated with
        service_description     PING            ; The service description
        check_command           check_ping!200.0,20%!600.0,60%  ; The command used to monitor the service
        normal_check_interval   5               ; Check the service every 5 minutes under normal conditions
        retry_check_interval    1               ; Re-check the service every minute until its final/hard state is determined
        
 contact_groups    wadmins

}

Any ideas ?

You need to add these options in your hosts definitions (and services):

Code:

        notification_interval           30
        notification_period             24x7
        notification_options            w,u,c,r

Where notification_interval is in minutes; notification_period is defined timeperiod; and notification_options are a comma separated list containing: w,u,c,r (w = Warning, u = Undefined, c = Critical, r = Recovery)

A timeperiod is defined like this:

Code:

# '24x7' timeperiod definition
define timeperiod{
        timeperiod_name 24x7
        alias           24 Hours A Day, 7 Days A Week
        sunday          00:00-24:00
        monday          00:00-24:00
        tuesday         00:00-24:00
        wednesday       00:00-24:00
        thursday        00:00-24:00
        friday          00:00-24:00
        saturday        00:00-24:00
        }

And you will only receive notifications within those time periods.

Hope this helps.

Thanks for your reply, but options you gave are only about when and who to contact.

Should it not send an email regardless, from host definition structure?

Because it does send email once I put it in service structure.

Well there may be a place to set a default value somewhere, but I have always set it for each host and service. I have over 100 hosts and over 500 services monitored by Nagios and I have something like 10 groups. Some get e-mails 24x7, some don't care if the copier goes down at 3 AM. I have never had a problem.

If you don't define

Code:

notification_interval   120
        notification_period     24x7
        notification_options    d,u,r

How is it to know who to contact and how often if you don't' tell it?
