RabbitMQ doesn't process Queue

This problem may happen for different reasons. One of the possible cases: exchange bindings were not created in the RabbitMQ. In this case, RabbitMQ couldn’t push received messages to the Queue.

Symptoms:

1. Magento is configured for the RabbitMQ

2. Our module is configured to use the RabbitMQ

3. When we add records to the Prequeue or Queue - not one item was processed for the long time (10-20 minutes)

Investigation steps:

1. Make sure all necessary consumers are running on your server, use the following command for that:

   ps -aux|grep 'Salesforce'
   Open

   

2. Make sure all our Queues were created in the RabbitMQ:
   
   

   1. tnw_salesforce.prequeue.process.amqp

   2. tnw_salesforce.queue.process.amqp

   3. tnw_salesforce_sync_realtime
      
      

      Open

      

3. Make sure all Exchanges were created successfully:
   
   

   
   
   

   1. tnw_salesforce.prequeue.amqp

   2. tnw_salesforce.queue.amqp

   3. tnw_salesforce.sync.amqp

4. Check these Exchanges Bindings, if no Bindings here - this is the reason if our issue:
   
   

    

Solution:

If you don’t see the Bindings - you need to create them manually. Use appropriated form on the Exchange page for that.

As a result, you should see the next result:
