Lists and Alerts Business logic has the functionality to send alarms to Milestone, either for Milestone alerts (which work consistently) or Milestone Analytic events.
Set the IP address in Data Factory Lists and Alerts Business logic:
You have to allow port 9090 in milestone analytic events.
Then you have to create an analytic event in Milestone with the same name as group in DataFactory.
Then you have to create an Alarm definition with your parameters (comment, source, etc). Also with the same name as group in DataFactory.
This setup could help you to send a notification to the Milestone system.
