Alert messages does not show device details

I find some difference between as Graylog 3.1.2-1 and older version 3.0.2-1. Most important thing is alert mail comes without deep informations. I created a stream and notification for “EventID: 4625”. It works and sends mail to admin account. But it shows only stream name and alert name as you can see below.
event%20not

In older versions we could see more information about log. Like hostname, ip address etc. I tried to edit email body from web interface, but i couldn’t get any proceed about issue.

Also i can see all detail about issue inside of streams. Just i couldn’t get this detail on mail notification.

Can someone share if there is a solution for get more information about logs on mail?

Thanks in advance

Hello,
try to check in Alerts - Event definitions in tab Notification, that you correctly setup parameter Message Backlog to 1 (or more if you need), which is Number of messages to be included in Notifications. If you don’t setup this parameter, backlog in e-mail message body will be empty.

If you want to show for example some custom fields use this snippet:

${foreach backlog message}
Source device: ${message.source}
Username: ${message.fields.username}
IP: ${message.fields.src_ip}
${end}

yea i missed the point what you show me. thanks for your reply it works very clear now
