Ruby on Rails logger - not recording all information

[niciliketo]

Is your feature request related to a problem? Please describe.
When using GCP logging, with our production mode rails application, we only get one line of logging per http request. In the default rails log file, there will be multiple lines per request.
This is important, because much of the information is lost when only the first line is logged

Describe the solution you'd like
I would like to see all the data which Rails logs to be availalble in Google Logging.

Describe alternatives you've considered
We have a temporary workaround, which is to include the following in our Rails application.rb file. This allows us to see the request params.

      config
        .google_cloud
        .logging
        .labels = {
          'request_parameters' => lambda do |rack_env|
            hsh = rack_env['rack.request.form_hash']
            return 'none' unless hsh

            filterer.filter(hsh).to_s
          end
        }

The other alternative we have considered is not using centralised logging (but this isnt really practical).
