QUESTION
I am trying to receive and send simple messages from two web APIs using RabbitMQ. It is a pretty simple code for now, and I am trying to see if both the APIs are properly able to communicate with each other. The issue is that I am not receiving all the messages and unable to establish a pattern between those that I am losing and those I am receiving. Below is the sample code.
For sending messages

QUESTION
We are looking to upgrade to the latest version of RabbitMQ so I have installed Erlang 24.0 and RabbitMQ 3.8.16 onto a Windows 10 PC for testing. I have the two RabbitMQ configuration files (rabbitmq.conf and advanced.config) stored in a folder called C:\RabbitMQ. The advanced.config contains static shovel configuration. I cannot get RabbitMQ to recognise the advanced.config file. Has anyone encountered this problem before?
We have earlier installs of RabbitMQ (i.e. Erlang 22.1 an RabbitMQ 3.8.2) running on Windows Server 2019 and these earlier versions load both config files with no issues.
All of our RabbitMQ installations store the config files in a folder called C:\RabbitMQ. We then set three environment variables to ensure that RabbitMQ recognises the folder and files:
- RABBITMQ_ADVANCED_CONFIG_FILE - C:\RabbitMQ\advanced
- RABBITMQ_BASE - C:\RabbitMQ
- RABBITMQ_CONFIG_FILE - C:\RabbitMQ\rabbitmq
I have followed the advice on the RabbitMQ config page https://www.rabbitmq.com/configure.html with regard to verifying the config file location.
I have also run the rabbitmq-diagnostics command which shows that only one config file is being loaded:
If I run the same command on our earlier installation then I can see that both files are being loaded:

How do I put my RabbitMq exchange to an asyncapi definition?
In the examples I found this ...

Answered 2021-Jun-11 at 19:02There is an entire exchange
property you can use for the channel binding for AMQP. The binding you are currently using is the operation binding.
This means that you can define it as such
QUESTION
erlang version = 1:24.0.2-1
rabbitmq-server version = 3.8.16-1
Recently installed latest rabbitmq on Ubuntu20. I verified that all was working fine and consumer was consuming the notification from messaging queue as required.
After approximately a day, rabbbitmq crashed as there was 0 disk space left.
After analysis found that around 10G was consumed by msg_store_transient, to which restarting rabbitmq solved the issue. But after a day, it happens again.
Can someone help me further?
...ANSWER
Answered 2021-Jun-06 at 12:54most likely you are consuming messages without sending back the basic_ack

Answered 2021-Jun-11 at 11:33You don't need to unpack the charts/*.tgz
file. If they're in that directory (and still packed up) then Helm will use them to run the deployment. Helm won't contact the external chart repository on its own, only when you run the helm dependency
commands.
After you run helm dep up

QUESTION
I'm developing an api that communicates with other services from an event architecture using RabbitMQ Topics. Several routes from my API will publish events and I would like to have a single live connection at all times in my API. That way, at every new request I just create a new channel, and keep only one connection (I decided to do this after reading about how expensive an amqp 0-9-2 connection is).
For now I have something like this:
...ANSWER
Answered 2021-Jun-11 at 07:52form the official pika documentation
Is Pika thread safe?
Pika does not have any notion of threading in the code. If you want to use Pika with threading, make sure you have a Pika connection per thread, created in that thread. It is not safe to share one Pika connection across threads, with one exception: you may call the connection method add_callback_threadsafe from another thread to schedule a callback within an active pika connection.
so your solution can work with a single thread
QUESTION
I'm trying to create a unit test that will test my MassTransit (RabbitMq) consumer. My consumer is expected a bus header key called UserName
. I've simplified my consumer class as follows. I need to find a way to mock the bus header data otherwise the test will always raise an exception when it executes context.Headers.TryGetHeader("UserName", out object value)
I'm using the NSubstitute mocking library. So how do I mock the ConsumeContext
type, and set a mock header value? I prefer a solution with NSubstitute
ANSWER
Answered 2021-Jun-09 at 12:03You don’t mock header values when using MassTransit, you just have to set them when you’re sending the message using the test harness. There is absolutely zero need for a mocking framework.

We really tried a lot but it still can not get the Symfony RabbitMQ bundle (https://github.com/php-amqplib/RabbitMqBundle) running in AWS (with Docker). AWS only allows AMQPS and port 5671 to be opened in the AWS managed service.

Install RabbitMQ
You can use RabbitMQ like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the RabbitMQ component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
