# Get the telemetry information

GET http://os-992244000006.local/api/v1/sensor/telemetry

Get the sensor telemetry information

Reference: https://docs.ouster.com/sensor-docs/firmware/api-reference/ouster-http-api/alerts-diagnostics-and-telemetry/get-telemetry

## Response

### 200

Valid telemetry query result

- `timestamp_ns` (uint64, optional) — Time at which the information was collected
- `phase_lock_status` (enum, optional) — The current phase-lock status will not indicate loss of lock if the time synchronization is lost.
  - Allowed values: `LOCKED`, `LOST`, `DISABLED`
- `input_voltage_mv` (integer, optional) — Reports system input-voltage in millvolts
- `internal_temperature_deg_c` (integer, optional) — Reports system temperature in degrees C Only available on Rev 06 and above sensors.
- `input_current_ma` (integer, optional) — System input-current in milliamps
