## Inventory

Captured at enrollment:

* Driver and CUDA versions
* Every GPU's **UUID** — the identity anchor for hardware-change detection
* VRAM and MIG mode
* The interconnect topology matrix

## Per-GPU live charts

Utilization, VRAM, temperature, and power — plus **ECC single/double-bit** and
**Xid** lifetime counters.

<Note>
  ECC and Xid counters are the numbers that tell you whether the silicon is
  healthy. They are lifetime counters, so what matters is the *rate of change*
  against a known-good baseline, not the absolute value on a card that has been
  running for a year.
</Note>

## Conditions

Agent-reported health checks with reasons:

* NVML availability
* Clock skew
* Buffer pressure

## Log viewer

Search by time range, level, source, or free text. **Follow** mode tails live.
Xid and NVRM lines are highlighted.

## Hardware changes

| Event         | Meaning                                                        |
| ------------- | -------------------------------------------------------------- |
| `gpu_missing` | A GPU UUID that was there has vanished                         |
| Hardware swap | A new UUID appeared — flagged for your explicit acknowledgment |

Because identity is the UUID rather than a slot index, a card moved between
slots is not reported as a swap, and a card silently replaced with a different
one cannot pass as the original.
