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 QGroundControl starts you should see a separate console window open which will have the log output

  • OSX

    • You must run QGroundControl 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.
