How to enable notification?

[tezarin]

Hi all,

Edit - I just edited my first post and fixed all of the other errors, the ones remaining are below. BAsically I would like to enable notifications in Nagios:

I just installed Nagios and after modifying the config files I am getting an error:

Code: Select all

Error: Contact 'nagiosadmin' has no service notification commands defined!
Error: Contact 'nagiosadmin' has no host notification commands defined!

Any info would be much appreciated

Below is a contact with all of the possible directives. Notice host_notification_commands and service_notification_commands. It would appear you don't have those.

Code: Select all

define contact{
	contact_name	contact_name
	alias	alias
	contactgroups	contactgroup_names
	minimum_value	#
	host_notifications_enabled	[0/1]
	service_notifications_enabled	[0/1]
	host_notification_period	timeperiod_name
	service_notification_period	timeperiod_name
	host_notification_options	[d,u,r,f,s,n]
	service_notification_options	[w,u,c,r,f,s,n]
	host_notification_commands	command_name
	service_notification_commands	command_name
	email	email_address
	pager	pager_number or pager_email_gateway
	addressx	additional_contact_address
	can_submit_commands	[0/1]
	retain_status_information	[0/1]
	retain_nonstatus_information	[0/1]
   	}

Take a look at https://assets.nagios.com/downloads/nag ... ml#command and you'll see how to define commands.

Do you have a commands.cfg? If so, can you attach it? If you aren't sure you can check with find / -name commands.cfg

Thanks for your reply. I have the commands.cfg:

Code: Select all

define command {
    command_name    check_memory
    command_line    $NAGIOSPLUGINSDIR$/check_memory -w 90 -c 95
}

define command {
    command_name    check_disk
    command_line    $NAGIOSPLUGINSDIR$/check_disk --warning 10% --critical 5% /
}

}
define command {
    command_name    local_check_disk_root
    command_line    $NAGIOSPLUGINSDIR$/check_disk --warning 30% --critical 15% /
}

define command {

    command_line    $NAGIOSPLUGINSDIR$/check_disk --iwarning 30% --icritical 15% /

define command{

        }

define command{
        command_name    service-notify-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\\

$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
        }

And I just modified my contacts so it reads:

Code: Select all

define contact{
        name                            generic-contact         ; The name of this contact template
        service_notification_period     24x7                    ; service notifications can be sent anytime
        host_notification_period        24x7                    ; host notifications can be sent anytime
        service_notification_options    w,u,c,r,f,s             ; send notifications for all service states, flapping events, and scc
heduled downtime events
        host_notification_options       d,u,r,f,s               ; send notifications for all host states, flapping events, and schedd
uled downtime events
        service_notification_commands   notify-service-by-email ; send service notifications via email
        host_notification_commands      notify-host-by-email    ; send host notifications via email
        register                        0                       ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL CONTACT, JUST A TEMM
PLATE!
        }


define contact{
        contact_name                    nagiosadmin             ; Short name of user
        alias                           Nagios Admin            ; Full name of user

# We only have one contact in this simple configuration file, so there is

define contactgroup{

        alias                   Nagios Administrators
        members                 nagiosadmin
        }

Does it look good? How can I test to see if it works?

Thanks

Not really. You are using the same command for hosts and services. This could work, but it's not really the way it's supposed to work.

Make a service go critical or a host go down, based on your current config (and assuming everything is up and ok now)
