Description of problem:

Run "/usr/bin/smart-proxy-openscap-send" manually and it will exit immediately without doing anything.

The log file is empty and last update since Feb.
# ls -lrt /var/log/foreman-proxy/openscap-send.log
-rw-r--r--. 1 foreman-proxy foreman-proxy 0 Feb 16  2017 /var/log/foreman-proxy/openscap-send.log

When debugging the script, I found that the plugin settings are not loaded.

1) Edit "/usr/bin/smart-proxy-openscap-send"

puts "Plugin settings: #{Proxy::OpenSCAP::Plugin.settings.to_h}" <==== add this line

# Don't run if OpenSCAP plugin is disabled.
exit unless Proxy::OpenSCAP::Plugin.settings.enabled == true  <===== Script will exit here if enabled is not true

2) Run it again

# /usr/bin/smart-proxy-openscap-send
Plugin settings: {}          <=========== Setting is empty

Tested in Satellite 6.2.15 too and it works.

I found that in Satellite 6.2, the module will autoload the settings if not loaded, but in Satellite 6.3 it will just assign an empty OpenStruct object.

3) Edit /usr/share/foreman-proxy/lib/proxy/pluggable.rb file.

  attr_writer :settings
  def settings
    @settings ||= Proxy::Settings.load_plugin_settings(plugin_default_settings, settings_file)   <=== Add this line that I copy from Satellite 6.2.15
    #@settings ||= OpenStruct.new   <==== Comment out this line
  end

4) Run it again. The plugin settings are loaded now

/usr/bin/smart-proxy-openscap-send
Plugin settings: {:enabled=>true, :spooldir=>"/var/spool/foreman-proxy/openscap", :openscap_send_log_file=>"/var/log/foreman-proxy/openscap-send-22222222.log", :contentdir=>"/var/lib/foreman-proxy/openscap/content", :reportsdir=>"/var/lib/foreman-proxy/openscap/reports", :failed_dir=>"/var/lib/foreman-proxy/openscap/failed", :tailoring_dir=>"/usr/share/foreman-proxy/lib/../openscap/tailoring", :corrupted_dir=>"/var/lib/foreman-proxy/openscap/corrupted"}
