Tracks instances whose UUID is duplicated or becomes associated with multiple, different host names, or connections, over a specific time period. These changes are measured by rate, that is, by a defined number of changes over the defined time period.
Change Rate: number of changes per time frame.
Every: time frame in which the changes are tracked.
For example, if the Change Rate is set to 5, and Every set to 10 minutes, and the UUID of the instance changed hostname 5 times in 8 minutes, an event is generated.
