### Ping every NAS

`GET /api/v1/admin/nas/ping`

Probes all of the tenant's devices from the platform and reports reachability. An operator action.

- Authentication: manager session (JWT) or API token
- Permission: `prm_nas_index` (View NAS)
- Risk: read
- Rate limit bucket: `t_probe`

#### Note

On the per-tenant probe budget — 10 a minute on a standard licence, shared with every other probe endpoint. For continuous reachability, read ping_status off the NAS list instead: the background sweep maintains it for free.
