[nagios] send emails to gmail when services are down.


Hello,

so as the title says.
these days i've been trying to send emails to my gmail account and it works now.
thanks to those who helped in my previous thread(: [http://www.linuxquestions.org/questi...ubuntu-823461/] much appreciated.
i'm now just short of one thing:
using postfix, how do i make nagios send notifications to my gmail account when any services go down?

i saw this commands for email in commands.cfg:

Code:
# 'notify-host-by-email' command definition
define command{
        command_name    notify-host-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" |/usr/bin/mailx -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
        }

# 'notify-service-by-email' command definition
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$SERVICEOUTPUT$" | /usr/bin/mailx -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$

        }
i know that will be the format of the email if i can receive it.


so what am i missing?

i'm very confused regarding this.

thank you.

Great.

If you want to receive nagios notification just define your email id in contacts.cfg file

Code:
vi /usr/local/nagios/etc/object/contacts.cfg

define contact{
        contact_name                    nagiosadmin  
        use                             generic-contact 
        alias                           Nagios Admin    
        email                          nagios@localhost  <= enter your email id here   
}
And the restart nagios service

Hi,

i already defined my email id in contacts.cfg:

Code:
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
        host_notifications_enabled      1
        service_notifications_enabled   1
        host_notification_period        24x7
        service_notification_options    w,u,c,r
        host_notification_options       d,u,r
        service_notification_commands   notify-service-by-email
        host_notification_commands      notify-host-by-email
        email                           xanios@gmail.com   ; email
        }

generally nagios.log file stored in

Code:
/user/local/nagios/var/nagios.log
as your mail.log file there is no mail sent by nagios user.

monitor nagios.log file and check is there any log which says service-notification-sent via email.

there isn't any log which "service-notification-sent via email"
it just basically shows the different services i'm monitoring for the different servers.

Nevermind it works already.(:
now i'm able to receive nagios email notifications.

i simply just changed this part:

Code:
define command{
       command_name    notify-host-by-email
       command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HO
STADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEM
AIL$
       }

# 'notify-service-by-email' command definition
define command{
       command_name    notify-service-by-email
       command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddre
ss: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ Servi
ce Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
       }
just change /usr/bin/mailx to /usr/bin/mail instead. and it works
thanks to those who've replied.
