Nagios Support Forum

Hello Guys,

i have installed nagios-3.4.4 and nagios-plugiuns-1.4.16. All the features and services are working fine. I configured it for one cisco switch also. The problem is it do not send the alert notification to my email provided in contacts.cfg
Instead they are being saved in /var/spool/mail/root

i am new with linux, but last time i installed nagios-3.2.3 or something the email notifications were working fine.
my contacts.cgf is

define contact{
contact_name nagiosadmin ; Short name of user
use generic-contact ; Inherit default values from generic-contact template (defined above)
alias Nagios Admin ; Full name of user
email [email protected] ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ****** }

thank you in advance.

Can you show us a service definition with your contact defined for it?

Thanks for the reply Slansing..

But i am not sure which file you are asking for?
can you please elaborate a bit..

Without anything defined you will not receive any emails, because you are not monitoring anything. The service's would be defined at:

You may have something like this:

define service{
use local-service ; Name of service template to use
host_name localhost
service_description PING
check_command check_ping!100.0,20%!500.0,60%
contacts nagiosadmin
}

Also, see if you have anything interesting in the mail log:

is this what you ask for ...


define service{
use generic-service ; Inherit values from a template
host_name Outbound-Switch-21 ; 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
}

please let me know if anyone need more info ..... to have a clear picture

Since you don't have the nagiosadmin contact defined in the service definition, nagios will use the contact specified in the generic-service template. Can you show us the generic-service template definition? You will find it in the "templates.cfg": BTW, did you restart nagios after you entered your email in the "contacts.cgf"?

@ lmiltchev : thanks for reply.

result of templates.cfg

Define a template for switches that we can reuse
define host{
name generic-switch ; The name of this host template
use generic-host ; Inherit default values from the generic-host template
check_period 24x7 ; By default, switches are monitored round the clock
check_interval 5 ; Switches are checked every 5 minutes
retry_interval 1 ; Schedule host check retries at 1 minute intervals
max_check_attempts 10 ; Check each switch 10 times (max)
check_command check-host-alive ; Default command to check if routers are "alive"
notification_period 24x7 ; Send notifications at any time
notification_interval 30 ; Resend notifications every 30 minutes
notification_options d,r ; Only send notifications for specific host states
contact_groups admins ; Notifications get sent to the admins by default
register 0 ; DONT REGISTER THIS - ITS JUST A TEMPLATE
