First thing we will do is th generate the workload by sending messages to the RabbitMQ queue using the Producer app. The messages can be generated using the API call. Use the Application URL or FQDN of the Azure Container App for the Producer app to send the messages.
In my case the FQDN for the Producer app is https://techtalks-producer.happywater-d5036088.eastasia.azurecontainerapps.io
We will use Postman to send the messages to the RabbitMQ queue with 5000 messages. You can use any other tool of your choice like cURL, WGET etc to send a GET request using the following URL
https://techtalks-producer.happywater-d5036088.eastasia.azurecontainerapps.io/api/TechTalks/Generate?numberOfMessages=5000
As we can see from the screenshot above, the API call returns the status code 200 indicating that the call was successful. We can also see the messages in the RabbitMQ queue using the RabbitMQ management console.
Note: Between the previous screenshot and this one, I have posted few more messages to the RabbitMQ queue using the Producer API. This is to show that the Consumer app is able to consume the messages from the RabbitMQ queue.
In the RabbitMQ management console, we can see that the messages are being consumed by the Consumer app. The screenshot below shows the messages being consumed by the Consumer app. We can see 1 consumer is running and 50 messages are being consumed. This 50 is the value we set in the RabbitMQ Dapr configuration as the prefetch count.
We can also verify the messages are being processed by the Consumer app using the logs. The screenshot below shows the logs for the Consumer app. We can see the messages are being processed by the Consumer app. In order to access the logs from the Azure Container Apps, navigate to the Azure Portal and select the Azure Container App for the Consumer app. Click on the Log Stream link under the Monitoring section.
We can see the different attributes related to the Tech Talk like Id, name, Category and Level printed in the log.
