Device Name Rediscovery — Refresh device display names from DNS/SNMP without full re-discovery
As a Network Engineer managing a multi-site, multi-vendor environment, I want PRTG to (re-)resolve and update the display names of existing devices from DNS or SNMP — on demand or on a schedule, with configurable rules for name/IP mismatches — so that my device tree always reflects accurate, current device names without me renaming hundreds of devices manually or maintaining custom rename scripts.
Background:
Sometimes a device doesn't have a DNS name or SNMP name, and the device is named as the IP address, or the name is changed due to reallocation. It would be nice if there were a way to rediscover just the name of the device. I have had to rename so many devices manually or via script, a rediscovery of the name would help a lot. Having some options on what to rediscover based on name/ip change criteria would be cool as well. if the name has changed is it a new device and should the whole thing be rediscovered?
