| Parameter | Description |
| ------------------------------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [SDLOG_MODE](../advanced_config/parameter_reference.md#SDLOG_MODE) | Logging Mode. Defines when logging starts and stops.<br />- `-1`: Logging disabled.<br />- `0`: Log when armed until disarm (default).<br />- `1`: Log from boot until disarm.<br />- `2`: Log from boot until shutdown.<br />- `3`: Log based on the [AUX1 RC channel](../advanced_config/parameter_reference.md#RC_MAP_AUX1).<br />- `4`: Log from first armed until shutdown. |
| [SDLOG_MODE](../advanced_config/parameter_reference.md#SDLOG_MODE) | Logging Mode. Defines when logging starts and stops.<br />- `0`: Log when armed until disarm (default).<br />- `1`: Log from boot until disarm.<br />- `2`: Log from boot until shutdown.<br />- `3`: Log based on the [AUX1 RC channel](../advanced_config/parameter_reference.md#RC_MAP_AUX1).<br />- `4`: Log from first armed until shutdown. |
| [SDLOG_BACKEND](../advanced_config/parameter_reference.md#SDLOG_BACKEND) | Logging Backend (bitmask). Setting a bit enables the corresponding backend. If no backend is selected, the logger is disabled.<br />- bit `0`: SD card logging.</br >- bit `1`: Mavlink logging.
| [SDLOG_PROFILE](../advanced_config/parameter_reference.md#SDLOG_PROFILE) | Logging profile. Use this to enable less common logging/analysis (e.g. for EKF2 replay, high rate logging for PID & filter tuning, thermal temperature calibration). |
| [SDLOG_MISSION](../advanced_config/parameter_reference.md#SDLOG_MISSION) | Create very small additional "Mission Log".<br>This log can _not_ be used with [Flight Review](../log/flight_log_analysis.md#flight-review-online-tool), but is useful when you need a small log for geotagging or regulatory compliance. |
Useful settings for specific cases:
- Raw sensor data for comparison: [SDLOG_MODE=1](../advanced_config/parameter_reference.md#SDLOG_MODE) and [SDLOG_PROFILE=64](../advanced_config/parameter_reference.md#SDLOG_PROFILE).
- Disabling logging altogether: [SDLOG_MODE=`-1`](../advanced_config/parameter_reference.md#SDLOG_MODE)
- Disabling logging altogether: [SDLOG_BACKEND=`0`](../advanced_config/parameter_reference.md#SDLOG_BACKEND)
