I am currently using auto discover to pull new servers from AWS into our PRTG. This is also adding devices that are not servers that only have an IP address and only get a Ping sensor. I'm not sure what these devices are. They seem to come and go. I can search my instances and they do not show up.
Is there a way of filtering out the devices that don't have DNS names, or maybe deleting them after the discovery is completed. I'm not sure how I would search for devices that only have an IP for a name to remove them from PRTG.
