6. Edit the
/usr/local/nagios/etc/objects/commands.cfg
file to add
$NOTIFICATIONCOMMENT$\n
after the
$SERVICEOUTPUT$\n
option in
notify-service-by-email
and in the
notify-host-by-
command definition.
# '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$SERVICEOUTPUT$\n $NOTIFICATIONCOMMENT$
\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/
$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
}
This section can also be modified to change the service which sends mail. To do so, change
/bin/mail -s
to the preferred mail service, for example
/bin/sendmail
.
7. Restart the Nagios service.
# service nagios restart
The Nagios server sends notifications during status changes to the mail addresses specified in the file. It is
important to note that:
●
By default, the system ensures three occurrences of the event before sending mail notifications.
●
By default, Nagios mail notifications are sent using the
/bin/mail
command. To change this, modify the
definition for the
notify-host-by-email
and
notify-service-by-email
commands in
the
/usr/local/nagios/etc/objects/commands.cfg
file and configure the mail server
accordingly.
