Notification Message Section
You can build the alarm messages that you are sending, including the subject, the body, the sender, and the recipient. In addition, you can create templates of subject and message combinations that you can reuse for other node configurations.

Template: In the drop-down list, select the desired message template. If you do not want to use a message template, select Do Not Use Templates. To manage the template list, do the following:
