How does it even work?

    
  database_nodes.keep_if{|n| n.server.present?}.collect do |n|
    {
      n.server.public_ip =>
        [:status, :repl_status, :last_status_check].collect { |a|
          {a => [:app, :db, :postgresql, a].inject(n){|h,k| h[k] if h.is_a?(Hash)} }
        }.reduce(Hash.new, :merge)
    }
  end
