What is acdDiscoveryLastChange?
This OID records the date and time when the device last sent discovery information to the network. Engineers monitor this timestamp to detect when devices have gone silent or disconnected unexpectedly. Example: a timestamp like "2024-01-15 14:32:05" tells you when the device last checked in; if it's hours old, the device may be unreachable.
