Troubleshooting

The following commands will need to be run on the server running rabbitmq.

Rabbitmq Queue Setup

Checking the existence of the queues and getting message counts.

Running this command:

rabbitmqctl list_queues

Should show something like this:

Listing queues ...
...
EmailQueue	0
RetryQueue	0
...

The 0 specifies the number of pending messages.

If there are messages in the queues you can check them by installing python and downloading rabbitmqadmin.

Download rabbitmqadmin:

wget https://raw.githubusercontent.com/rabbitmq/rabbitmq-management/rabbitmq_v3_6_14/bin/rabbitmqadmin

Check the first message in the EmailQueue:

python rabbitmqadmin get queue=EmailQueue requeue=true count=1

Should show something like this:

+-------------+---------------+---------------+------------------------------+---------------+------------------+------------+-------------+
| routing_key |   exchange    | message_count |           payload            | payload_bytes | payload_encoding | properties | redelivered |
+-------------+---------------+---------------+------------------------------+---------------+------------------+------------+-------------+
| SendEmail   | EmailExchange | 41            | ..pickledpayload...           | 28            | string           |            | True        |
+-------------+---------------+---------------+------------------------------+---------------+------------------+------------+-------------+

Rabbitmq Exchange Setup

Checking the existence of the appropriate exchanges.

Running this command:

rabbitmqctl list_exchanges

Should show something like this:

Listing exchanges ...
...
EmailExchange	direct
RetryExchange	direct
...

The second column is the type of exchange.
