Nagios FROM email address

[MarkCampbell]

This may be a stupid question, but I've been going throughout the UI looking for this and have only seen one field for the Nagios FROM email field, which I've found in nagiosxi/admin/mailsettings.php. I've changed it here to Nagios XI <[email protected]>, and when I tell it to send me a test email, I get it exactly as I typed it in... but when I receive actual alert emails, it comes as [email protected] (this server is in AWS, which defaults the hostname to the IP in dashes). Where else could this alternate email address be set?

HI Mark,

Thanks for trying out Nagios XI and welcome to the Nagios Customer Support Forum!

For clarification, are you using SMTP or Sendmail in your email settings ( a screenshot would be helpful)?

Regards,
Benjamin

I am using SMTP to connect to Amazon SES.

This is likely because those contacts are using the notify-host-by-email/notify-service-by-email commands. You can either do this:

https://assets.nagios.com/downloads/nag ... Mailer.pdf

Or you can edit the notify-host-by-email/notify-service-by-email commands in Configure > Core Config Manager > Commands and add an option to the mail command to set the From address:

The defaults:

notify-host-by-email:

Code: Select all

/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\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 $HOSTSTATE$ **" $CONTACTEMAIL$

notify-service-by-email:

Code: Select all

/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$

To: (for example, adding -S "from=Nagios XI <[email protected]>")

notify-host-by-email:

Code: Select all

/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -S "from=Nagios XI <[email protected]>" -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$

notify-service-by-email:

Code: Select all

/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /bin/mail -S "from=Nagios XI <[email protected]>" -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$

Then apply configuration and test.

Thanks that worked, I imported my configuration from a Nagios Core instance, but didn't realize it was overriding the use of the php mailer.

Glad that worked for you! Let us know when we're okay to lock this up and mark it as resolved.

Thank you!

[MarkCampbell]

I think I'm good to mark this as resolved.
