Failed to receive message from deepstream-test-4 (python)

Accelerated Computing Intelligent Video Analytics DeepStream SDK

I am running the deepstream test 4 on jetson but it fails to receive messages with a code provides in the link below in my computer: Deepstream test4 and AMQP nvmsg-broker error - #7 by camilosilva91
I changed the receiver.py credentials to admin, admin as well.

my config file for rabbitmq is like this:
[message-broker]
password = admin
#optional
hostname = localhost
username = admin
port = 5672
exchange = ds_exchange
topic = ds_topic

I also have changed these lines of code as I am using deepstream version 5.0

pyds.register_user_copyfunc(meta_copy_func)
pyds.register_user_releasefunc(meta_free_func)

with
pyds.set_user_copyfunc(user_event_meta, meta_copy_func)
pyds.set_user_releasefunc(user_event_meta, meta_free_func)

• Hardware Platform: Jetson NX
• DeepStream Version: 5.0

question 1: how can I be sure to take the messages so that I will get sure it is working.
question2: what should I expect as a message that nvmsgbroker will send.

HI,
You can open logging for analysis. recording failure function and description. also include message you sent.
sudo chmod +x sources/tools/nvds_logger/setup_nvds_logger.sh
sudo ./sources/tools/nvds_logger/setup_nvds_logger.sh
please make sure you send message successfully first.

Thank you for your response.
I was able to see the logs in the way you said but I still cannot run the reciever to be able to see the messages on another device.
I would be grateful if you can help me with this. Thanks.

I am not sure about the outside app, can you try with
1 Consume messages:

#Install the amqp-tools
sudo apt-get install amqp-tools

cat < test_amqp_recv.sh
while read -r line; do
echo “$line”
done
EOF

chmod +x test_amqp_recv.sh

2 Run the consumer:
amqp-consume -q “myqueue” -r “topicname” -e “amq.topic” ./test_amqp_recv.sh // “queue topic exchange” change accordingly.
