Issue with notify-service-by-email command

[Sampath.Basireddy]

I am trying to use notify-service-by-email command to send out email alerts, but doesn't seem to be working.

Here is the syntax of the command:

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

Any thoughts.



Thank You.

Can you go to the Admin > Manage Email settings menu and post the Mail Method the server is setup to use?
To use the notify-service-by-email command, the server has to be using Sendmail as the mail method.
If the server is setup to use a SMTP server, the command would have to use is xi_service_notification_handler for that user account.

You may want want to take a look at these documents for more details.

Yes, we are using "Sendmail" mail method.

So you have that method assigned to a contact and the contact assigned to a host/service that is going down correct?

Can you post the configuration for the contact (feel free to block out email address )

[Sampath.Basireddy]

Here is the contact config from contacts.cfg.

Code: Select all

define contact {
        contact_name                            IT-Monitoring
        alias                                   DL for IT-Monitoring
        host_notifications_enabled              1
        service_notifications_enabled           1
        host_notification_period                xi_timeperiod_24x7
        service_notification_period             xi_timeperiod_24x7
        host_notification_options               d,u,r,f,s,
        service_notification_options            w,u,c,r,f,s,
        host_notification_commands              notify-host-by-email
        service_notification_commands           notify-service-by-email
        email                                   <Email ID>
        use                                     generic-contact
        }

So you have that method assigned to a contact and the contact assigned to a host/service that is going down correct?

Also, can you describe what is happening?

Can you see the notification in the Notification Report?

Can you see the email attempt in /var/log/maillog ?

[Sampath.Basireddy]

Yes, I do see an email attempt .

[scottwilkerson]

This shows the nagios server delivered the message to the next mail server, if it wasn't delivered you would need to check logs on that server
