Abstract

Customize the email and ticket notifications generated by the Active Response playbook.

You can customize the following notifications and information sent by the Active Response playbook:

  • The subject and body text of email or ticket notifications sent by the playbook to potential service owners.

  • The subject and body text of email or ticket notifications sent to the service owner after an alert was resolved by automated remediation.

  • The Jira project key that will be associated with any Jira tickets created by the playbook.

In addition to specifying the text to include in notifications, you can also include system variables. Variables enable you to include the alert-specific information that your organization uses in their workflow.

Customizing the playbook notifications is optional. If you do not customize the notifications, the playbook will use the default text and formats described in Active Response Templates.
