Debugging MEGAcmd

There are two different kinds of logging messages:

  • MEGAcmd based: those messages reported by MEGAcmd itself.

These messages will show information regarding the processing of user commands.

  • SDK based: those messages reported by the sdk and dependent libraries.

These messages will show information regarding requests, transfers, network, etc. They will be labeled with API:.

MEGAcmdServer logs messages depending on the level of log adjusted to those two categories. You can adjust the level of logging for those kinds with log command. Log levels range from FATAL (the lowest) to VERBOSE (the highest).

How to access the logs

Accessing the logs depends on the platform you are in.

MacOS

By default, whenever MEGAcmdServer is executed, it will log the output into $HOME/.megaCmd/megacmdserver.log.

If you want to launch it manually execute in a terminal:

export PATH=/Applications/MEGAcmd.app/Contents/MacOS:$PATH
./mega-cmd

Linux

By default, whenever MEGAcmdServer is executed, it will log the output into $HOME/.megaCmd/megacmdserver.log.

If you want to launch it manually execute in a terminal:

mega-cmd-server

Windows

MEGAcmdServer is executed in the background without saving the log into a file. If you want to see the output you would need to execute the server (MEGAcmdServer.exe) manually.

Verbosity on startup

You can start the server with higher level of verbosity in order to have log levels increased at startup. In Windows & Linux you will need to pass --debug-full as an argument to the executable (e.g: MEGAcmdServer.exe --debug-full).

In MacOS, you can use MEGACMD_LOGLEVEL environment variable like this: MEGACMD_LOGLEVEL=FULLDEBUG ./mega-cmd.

If you want other startup level of loggin, you can use:

  • --debug
  • MEGACMD_LOGLEVEL=DEBUG

This will set:

MEGAcmd log level = DEBUG SDK log level = DEFAULT

  • --debug-full
  • MEGACMD_LOGLEVEL=DEBUG

This will set:

MEGAcmd log level = DEBUG SDK log level = DEBUG

  • --verbose
  • MEGACMD_LOGLEVEL=VERBOSE

This will set:

MEGAcmd log level = VERBOSE SDK log level = DEFAULT

  • --verbose-full
  • MEGACMD_LOGLEVEL=FULLVERBOSE

This will set:

MEGAcmd log level = VERBOSE SDK log level = VERBOSE

Controlling verbosity of a single command

You can pass -v (-vv, -vvv, and so on for a more verbose output) to an specific command and it will use higher level of verbosity of MEGAcmd based messages.
