Misleading field label "GPU Device IDs Detected" in dcgmi diag output #282

DCGM Version: 4.4.1 / 4.5.2

Description:

The dcgmi diag output displays a field labeled "GPU Device IDs Detected" which shows identical values for all GPUs:

| GPU Device IDs Detected   | 3182, 3182, 3182, 3182, 3182, 3182, 3182       |

This is misleading because:

  • "GPU Device IDs" implies unique per-GPU identifiers
  • Users expect N different values for N GPUs
  • The actual values shown are PCI Device IDs (hardware SKU), which are identical for all GPUs of the same model

Expected behavior:

Either:

  1. Rename the field to accurately reflect what it shows: "PCI Device IDs Detected" or "GPU Model IDs"
  2. Or show actual unique GPU identifiers (UUIDs, indices, or serial numbers)

Reproduction:
bash
dcgmi diag --run 1

On any system with multiple identical GPUs.
