Email notifications can be customized in Analytics 20.2 and later only.

1. SSH to your Analytics node
2. Go to /opt/versa/var/van-app/templates/notifications
   
   

$ cd /opt/versa/var/van-app/templates/notifications

The available templates are,

• reporting_notification.vm
• system_alert_notification.vm

Images must be integrated inside the template in a base64 format. Email template engine do not support images located in a separate file.

To do this,

1. Convert your image into base64 using this converter: http://www.dailycoding.com/Utils/Converter/ImageToBase64.aspx
2. Include the base64 string to your image tag as follow
   
   

<img alt="myimage" src="data:image/png;base64,<BASE_64_STRING_HERE>" />

When done, simply save your changes. You don't need to restart Analytics.

You will need to copy your changes to all your Analytics nodes within your cluster.
