Console Logging

The Console can be helpful tool for diagnosing QGroundControl problems. It can be found in the Setttings view. It allows you turn turn on/off the logging options available in QGroundControl. Click the "Set Logging" button to select logging options.

Commonly used logging options

  • LinkManagerLog, MultiVehicleManagerLog - Debug connection problems.
  • LinkManagerVerboseLog - Very noisy connection problem debugging. Continuous output of available serial ports.
  • FirmwareUpgradeLog - Debug firmware flash issues.
  • ParameterLoaderLog - Debug parameter load problems.
  • ParameterLoaderVerboseLog - Debug parameter load problems with full trace of parameters coming/going/in system.
  • MissionManagerLog - Debug mission protocol issues.
  • RadioComponentControllerLog - Debug Radio calibration issues.

Logging from the command line

An alternate mechanism for logging is using the --logging command line option. This is handy if you are trying to get logs from a situation where QGroundControl crashes.

How you do this and where the traces are output vary by OS:

  • Windows
    • You must open a command prompt, change directory to the qgroundcontrol.exe location, and run it from there:
    • cd "\Program Files (x86)\qgroundcontrol" qgroundcontrol --logging:full
    • When QGC starts you should see a separate console window open which will have the log output
  • OSX
    • You must run QGC from Terminal. The Terminal app is located in Applications/Utilities. Once Terminal is open paste the following into it:
    • cd /Applications/ ./qgroundcontrol --logging:full
    • Log traces will output to the Terminal window.
  • Linux
    • ./ --logging:full
    • Log traces will output to the shell you are running from.
