Blitzy - A simple HTTP load tester in Elixir

Distributed Blitzy

It is way more fun to start distributed. Edit the provided config/config.exs with whatever node name suits your fancy. This is optional, and you can stick to the provided one.

config :blitz, master_node: :"a@127.0.0.1"

config :blitz, slave_nodes: [:"b@127.0.0.1", 
                             :"c@127.0.0.1",
                             :"d@127.0.0.1"] 

Here, the master node is :a@127.0.0.1; the rest are slave nodes.

Start up a couple of nodes, and name them accordingly. For example, here's how to start one of them:

% iex --name b@127.0.0.1 -S mix

Now, when you run the the command

% ./blitzy -n 100 http://www.bieberfever.com

the requests will be split across the number of nodes you created, including the master node. Here's an example run:
