In my last post I have shared some results from Benchmarking RabbitMQ on Raspberry Pi.
I have also promised to go into more detail about the setup for these benchmarks later. So here we go:
Step 1 - housekeeping
I will be using Raspbian on two Raspberry Pi 1 boxes, called rpi01 and rpi02, and one Model 2, obviously named rpi03. So we do in each case
rpi01$ sudo apt-get update rpi01$ sudo apt-get upgrade rpi01$ uname -a
the last command will return the following for Model 1 vs. Model 2
Linux rpi01 3.18.11+ #781 PREEMPT Tue Apr 21 18:02:18 BST 2015 armv6l GNU/Linux Linux rpi03 3.18.11-v7+ #781 SMP PREEMPT Tue Apr 21 18:07:59 BST 2015 armv7l GNU/Linux
We see, the only difference is that the Model 2 has a armv71 machine id and has SMP enabled because it is a multi-core CPU. The Kernel version also shows a ‘-v7’ suffix, but otherwise same number.
Step 2 - get rabbitmq
I have extracted from the original documentation at [http://www.rabbitmq.com/documentation.html] (http://www.rabbitmq.com/documentation.html) which steps were needed to get things up and running.
install via apt
(see [http://www.rabbitmq.com/documentation.html] (http://www.rabbitmq.com/documentation.html)). Use a text editor of your choice and add the following line to the file /etc/apt/sources.list (you need sudo privileges for this).
deb http://www.rabbitmq.com/debian/ testing main
execute the following commands:
rpi01$ wget https://www.rabbitmq.com/rabbitmq-signing-key-public.asc rpi01$ sudo apt-key add rabbitmq-signing-key-public.asc rpi01$ sudo apt-get update rpi01$ sudo apt-get install rabbitmq-server
check rabbitmq is running
rpi01$ sudo rabbitmqctl status
In my benchmarks I have used RabbitMQ version 3.5.3
## Step 3 - configuration
configure user and admin web ui
rpi01$ sudo rabbitmqctl add_user <user> <password> rpi01$ sudo rabbitmqctl set_user_tags <user> administrator rpi01$ sudo rabbitmqctl set_permissions -p / mq ".*" ".*" ".*" rpi01$ sudo rabbitmq-plugins enable rabbitmq_management
now you should be able to see the management console with a web browser:
Step 4 - get the benchmark tools
HOW TO RUN
first, make sure you have java installed, then clone this repo and from within the repo folder, do:
to set up the tools, then you will need to edit the file ‘spec.js’ in each of benchmark scenario folders ‘./scenario-*’ to have valid AMQP URI’s for your rabbitMQ broker. You can also create new scenario’s by copying the ‘spec.js’ file to a new scenario folder.
Then run your scenario’s with
This will create (or overwrite) the result.js in each of the scenario folders.
You can visualize this with the report.html file in each scenario file. Depending on your browser you may not be able to view this via the “file://..” url, then you just could just fire up a local web server like so:
$ python -m SimpleHTTPServer
The results of this exercise have been already explained in my last post Benchmarking RabbitMQ on Raspberry Pi so I recommend you head over to see what I got out of it.
