You're going to use Apache JMeter with the AMQP plugin to generate load on RabbitMQ. For this first test, your goal is to basically saturate the logs-archiver.py script in order to determine what the maximum processing capacity of a single running instance of it. After starting JMeter, add a Thread Group element under the Test Plan element and configure it as shown in the following screenshot:

As you can see, we will use 50 concurrent threads, each publishing messages to RabbitMQ in an infinite loop. This is way more than the total number of servers at CCM but remember, we want to find out the upper limit of what we can actually achieve. The following screenshot shows the configuration of the element in charge of publishing messages to RabbitMQ by adding an AMQP publisher sampler:

Notice how you're simulating an Apache2 syslog message; the routing key is info.local2 (as per the...
