A string listing the notification IDs of previously reported alarms that this alarm correlates to, formatted as semicolon-delimited integers such as "notificationID1;notificationID2". Admins and correlation engines use this to understand that this new alarm implicitly clears and supersedes the listed earlier alarms rather than representing an entirely separate condition. For example, a value of "1042;1043" here would tell an operator that this alarm report resolves and replaces the two previously raised alarms with those notification IDs.
