Hi Alfredo,

If you are using XBaya to run experiments, you need to have rabbitMQ server
up and running in order to xbaya monitoring to work. To configure rabbitMQ
with airavata, follow the below steps.

   - Start RabbitMQ server
   - Stop the running airavata server
   - In, change the property "*publish.rabbitmq*"
   to true (*publish.rabbitmq=true*)
   - Start the airavata server again
   - Run echo experiment from xbaya again

Let us know whether this fix your problem.
