Nagios Support Forum

Hello,

I configured SSMTP to send emails, from the terminal I'm not having problems but sending email alerts for Nagios is not working.

I attach you the 2 commands that I have for send emails on commands.cfg

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

This what I have from \var/log/mail.log

On contacts.cfg I have the following

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 ******

}

I don't know whatelse to check, any idea?

Thanks in advance for helping me
Best regards

How did you configure you mail sending program?

What OS is this? What mail program is this?

You are sending mail as root@sdnagios01 which is likely not going to be accepted from remote SMTP server as there is no route back because the domain is invalid

Hello, finally I got this working.

Many thanks for the reply!!

Glad to hear its working
