Take a look at the documentation available on RHEL's site, https://access.redhat.com/documentation ... tions.html

This provides all of the information necessary to get notifications setup. Let us know if you run into any issues.

but you know better than me for example this path that said in step1 there is not in nagios server (/etc/nagios/gluster/gluster-contacts.cfg) on nagios server we have just one contact.cfg file on this path: /usr/local/nagios/etc/object/ and in this file there is not these configs :

Code: Select all

define contact {
        contact_name                            Contact1
        alias                                   ContactNameAlias
        email                                   email-address
        service_notification_period             24x7
        service_notification_options            w,u,c,r,f,s
        service_notification_commands           notify-service-by-email
        host_notification_period                24x7
        host_notification_options               d,u,r,f,s
        host_notification_commands              notify-host-by-email
}
define contact {
        contact_name                            Contact2
        alias                                   ContactNameAlias2
        email                                   email-address
        service_notification_period             24x7
        service_notification_options            w,u,c,r,f,s
        service_notification_commands           notify-service-by-email
        host_notification_period                24x7
        host_notification_options               d,u,r,f,s
        host_notification_commands              notify-host-by-email
}

Can you post the file /usr/local/nagios/etc/objects/contacts.cfg for us to look at?

Use that file for reference, and you can add your own contact in such as -

Code: Select all

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

Then, under your service assign 'baber' as a contact -

Code: Select all

define service {
        host_name       google.com
        service_description     HTTP
        check_period    xi_timeperiod_24x7
        check_command   check_http
        contacts        baber

        contacts        baber

thanks

but it is not working
i have do these steps :

1- edit contact.cfg file and attached that
2-add contacts nagiosadmin line to template.cfg

Code: Select all

define host{
        name                            linux-server    ; The name of this host template
        use                             generic-host    ; This template inherits other values from the generic-host template
        check_period                    24x7            ; By default, Linux hosts are checked round the clock
        check_interval                  5               ; Actively check the host every 5 minutes
        retry_interval                  1               ; Schedule host check retries at 1 minute intervals
        max_check_attempts              10              ; Check each Linux host 10 times (max)
        check_command                   check-host-alive ; Default command to check Linux hosts
        notification_period             workhours       ; Linux admins hate to be woken up, so we only notify during the day
                                                        ; Note that the notification_period variable is being overridden from
                                                        ; the value that is inherited from the generic-host template!
        notification_interval           120             ; Resend notifications every 2 hours
        notification_options            d,u,r           ; Only send notifications for specific host states
        contact_groups                  admins          ; Notifications get sent to the admins by default
        contacts                        nagiosadmin
        register                        0               ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
        }

3- also add this lione

contacts nagiosadmin

to one of my linux host in .cfg file

Code: Select all

define service{
        use                     local-service
        host_name               redhat6.4
        service_description     DNS
        check_command           check_nrpe!check_dns
        contacts                nagiosadmin
        }

4 - and add contacts nagiosadmin
line to template.cfg attached template.cfg file

5 -in /etc/nagios/objects/commands.cfg file add $NOTIFICATIONCOMMENT$\n after $SERVICEOUTPUT$\n option in notify-service-by-email

Code: Select all

define command{
        command_name    notify-service-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n $NOTIFICATIONCOMMENT$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
        }

Your templateuse local-service does not have any notification_options assigned to it, you will need these in order to have them triggered.

not working

i have attached all 4 config files

what is my problem ?

[rkennedy]

Please attach the file /usr/local/nagios/var/objects.cache for us to look at, and let us know which host / service AND contact you're not receiving notifications for.
