Hello, @anuruddhak. Can you show me the notification commands you're currently using? They should be in the /usr/local/nagios/etc/commands.cfg file.

[anuruddhak]

notify-host-by-email command

/usr/bin/printf "%b" "***** Location $HOSTNAME$ Health Report*****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$

I need to use below script with the notify-host-by-email command

cat <<EOF | sendmail -t
To: test_TO@gmail.com
Subject: Testing
From: Test_From@gmail.com
Cc: Test_CC@gmail.com

This is a test message
EOF

please note that I'm already integrate with Amazon SES with postfix that's wahy I used sendmail

@anuruddhak, You can use the following commands if you want to use the sendmail. Change my email address after -f to whatever email should be in the From field.

notify-host-by-email command

Code: Select all

/usr/bin/printf "%b" "Subject: $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$\n\n***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/sbin/sendmail -f "nik@nagios.com" -vt $CONTACTEMAIL$ 

notify-service-by-email command

Code: Select all

/usr/bin/printf "%b" "Subject: $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$\n\n***** 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/sbin/sendmail  -f "nik@nagios.com" -vt $CONTACTEMAIL$

You can change:

Subject: $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$

To whatever you want to have in the email subject, for example, "Test".



As far as CC multiple recipients, would the second email always be the same? You can create a separate contact in XI and have it use the same notification command. That way the notification will always fire for the second contact as well. Does this make sense?

[anuruddhak]

thank you for the support it's working now.

if I create the new contact in contact.cfg and mention in host configuration file under contact group it's working.but in the email unable to visible to email address.how can I fixed that ?

can we mention the cc email address in command like this

/usr/bin/printf "%b" "Subject: $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$\n\n***** 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/sbin/sendmail -f "nik@nagios.com" cc Test@gmail.com -vt $CONTACTEMAIL$

[scottwilkerson]

you should be able to add it like this

Code: Select all

/usr/bin/printf "%b" "Subject: $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$\n\n***** 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/sbin/sendmail -f "nik@nagios.com" -vt $CONTACTEMAIL$ cc:Test@gmail.com
