Hi Throwing something out there for advice. There are a number of datasources that are subject to duplication of instance because you cannot safely turn on the automatically delete as legitimate instances may go down for longer than 30 days. This appears to be due to them being very dependent on the instance name, so if this is something the customer has the ability to change then it creates another instance during Active Discovery. My question is if anyone has an ideas on a complex datapoint (or some other means) that can detect that this instance has matching property to another instance. This could be say auto.device.mac_address or even the Instance Value as these always match between the duplicate instances. This is really bugging me now so I really need to find a proactive way to address them. The real downside is that you lose the historical data when it is actually the same device. What the ideal would be is if you could merge instance or at least delete the new and rename the old one to the new ones name so its not discovered again.
