Set Log Level for Built in Keywords in Robotframework

Also, you can set your log level in the code. Like this:

  Test Setup                Set Log Level    TRACE

Then in the log.html file, a visible log level dropdown is shown in the upper right corner. This allows users to remove messages below the chosen level from the view. This can be useful especially when running tests at the TRACE level.
