# MCollective::Runner

The main runner for the daemon, supports running in the foreground and the background, keeps detailed stats and provides hooks to access all this information

### Public Instance Methods

run() click to toggle source

Starts the main loop, before calling this you should initialize the MCollective::Config singleton.

    # File lib/mcollective/runner.rb, line 37
    def run
      Data.load_data_sources

      Util.subscribe(Util.make_subscriptions("mcollective", :broadcast))
      Util.subscribe(Util.make_subscriptions("mcollective", :directed)) if @config.direct_addressing

      # Start the registration plugin if interval isn't 0
      begin
        PluginManager["registration_plugin"].run(@connection) unless @config.registerinterval == 0
      rescue Exception => e
        Log.error("Failed to start registration plugin: #{e}")
      end

      loop do
        begin
          request = receive

          unless request.agent == "mcollective"
            agentmsg(request)
          else
            Log.error("Received a control message, possibly via 'mco controller' but this has been deprecated")
          end
