Creating a Message Template on the LTS Console

A message template defines the format of alarm notification messages sent to subscribers. LTS provides built-in keywords_template and sql_template. Subscribers can select templates based on protocols. If the template of a specified protocol does not exist, the built-in template is used to send messages to subscribers of that protocol. When using a message template to send alarm notification messages, the system automatically replaces the template variables with the content in the alarm rule.

Creating a Message Template

1. Log in to the management console and choose Management & Deployment > Log Tank Service.
2. Choose Alarms in the navigation pane and click the Alarm Action Rules tab.
   

   By default, LTS provides the following built-in message templates. If no message content is configured in your selected template, LTS uses a built-in template instead.

   • keywords_template: keyword alarm template

3. Click Create on the Message Templates tab page. On the displayed page, set the required parameters.
   

   • The email content supports HTML tags and message preview.
   • You can create up to 100 message templates for AOM and LTS. If there are already 100 templates, delete unnecessary templates before creating a new one.
