        • Single: Log Service sends the two alert notifications in sequence. Content: { "project": "project-1", "alert_name": "alert-1"} and { "project": "project-2", "alert_name": "alert-2"}.
        • Batch: Log Service sends one message that includes the two alert notifications. Content: [{ "project": "project-1", "alert_name": "alert-1"}, { "project": "project-2", "alert_name": "alert-2"}].
          • If you select Batch and set the Maximum number of items sent in a group parameter to N, an alert notification for the first N alerts in a merged set is sent.
          • If you select Batch and the content that you specify can be parsed into JSON data, an alert notification is sent in the JSON format. If the content cannot be parsed into JSON data, an alert notification is sent as an array that contains strings.
      • Content: the content of an alert notification. You can directly enter content or use template variables to specify the content of an alert notification. For more information, see Variables in new alert templates.
