Log Setup (Analyze View)

The Log Setup screen (Analyze > Log Setup) helps you configure common ArduPilot logging parameters and provides practical troubleshooting guidance.

Common Parameters

The page exposes key parameters when they are available on the connected vehicle/firmware, including:

• LOG_BACKEND_TYPE
• LOG_BITMASK
• LOG_DISARMED
• LOG_FILE_DSRMROT
• LOG_FILE_MB_FREE
• LOG_FILE_RATEMAX
• LOG_BLK_RATEMAX
• LOG_MAV_RATEMAX
• LOG_MAX_FILES
• LOG_REPLAY
• EK3_LOG_LEVEL

All parameter edits are applied through the standard QGroundControl parameter system (Facts).

Troubleshooting Checklist

• Use a known-good SD card and verify it is writable.
• Keep enough free space for expected log size.
• If logs show missing samples, lower block/logging rate limits.
• Enable disarmed/replay logging only when needed for debugging, because file size increases.
• Download and clear logs regularly on low-capacity onboard flash.
