What is hgmpNTDPCacheChange?
This counter increments whenever the device table changes, ranging from 0 to 65535, helping administrators detect topology modifications without polling the full table. Engineers check this value before querying device details to avoid unnecessary data retrieval. A value change from 10 to 12 signals that two new devices or relationships were discovered.
