### Read near-real-time throughput

`GET /api/v1/admin/sessions/{id}/live-traffic`

Returns bits per second when the session's NAS has SNMP management credentials with an interface selector configured, by polling the device twice about a second apart. Without them it degrades to the accounting counters.

- Authentication: manager session (JWT) or API token
- Permission: `prm_users_live_traffic` (Live traffic / disconnect)
- Risk: write

#### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `id` | path | integer | yes | Session id. |

#### Note

Check the source field before trusting the numbers. source "snmp" is a real measurement; source "interim" means there were no SNMP credentials, the device was unreachable, or the sampler is not wired — the counters are the last accounting values and bps is 0, and your client has to derive the rate from successive polls itself.
