How can I get a list of all servers

[ilijamt]

Is it possible to get a list of all the servers I'm deploying too, so my message will show to which servers I'm also deploying.

you could define some helper method in your custom_messaging.rb

      def server_hostnames
        roles(:web).map do |host|
          "#{host.user}@#{host.hostname}"
        end.join(', ')
      end

      def payload_for_updating
        {
          text: "on server #{server_hostnames} " + super[:text]
        }
      end
