Usage

blackfire::default

Add agent Server ID and token and include blackfire in your node's run_list:

{
  "name":"my_node",
  "run_list": [
    "recipe[blackfire]"
  ],
  "blackfire": {
    "agent": {
      "server_id": "my-agent-server-id",
      "server_token": "my-agent-server-token"
    }
  }
}

blackfire::agent

Used if you wish to install only the agent.

blackfire::php

Used if you wish to install only the PHP extension.

Note about blackfire::php

This cookbook makes no assumption about the webserver you use.

Therefore this is your responsability to write a wrapper and notify your
webserver (ie. Apache or php5-fpm) for reload/restart or subscribe the good
resources.

You can obtain futher informations on wrapper cookbooks here:
https://www.getchef.com/blog/2013/12/03/doing-wrapper-cookbooks-right/

One way to do that (maybe the best to avoid disturbing logs messages):

include_recipe "blackfire"

begin
  r = resources(:ruby_block => "blackfire-php-restart-webserver")
  r.block do
  end
  r.notifies :reload, "service[php5-fpm]"
rescue Chef::Exceptions::ResourceNotFound
  Chef::Log.warn 'could not find resource "ruby_block[blackfire-php-restart-webserver]" to override!'
end
