Ohai, this is the author here... 
Since it's logging at debug level you'll need -l debug.
Actually, this handler is obsolete if you are on Chef 11.12.x, which
prints the cookbook versions as part of the beginning of the run:
$ sudo chef-client --force-logger

Hi there,
I just loaded the Cookbook from juliandunn to get some output with the
chef_handler. My code looks like the following:
Handler:
require 'chef/log'
module Opscode
class CookbookVersionsHandler < Chef::Handler
def report
cookbooks = run_context.cookbook_collection
Chef::Log.debug("Cookbooks and versions run: #{cookbooks.keys.map {|x|
cookbooks.name.to_s + " " + cookbooks.version} }")
end
end
End
Recipe:
chef_handler "Opscode::CookbookVersionsHandler" do
source "#{node["chef_handler"]["handler_path"]}/chf.rb"
supports :report => true
action :enable
End
At the end of the client run, the Handler will run, too. But I don’t get
some output:
Running handlers:
- Opscode::CookbookVersionsHandler
Running handlers complete
Chef Client finished, 4/117 resources updated in 20.13747256 seconds
How can I debug the missing Chef::Log message?
Thanks,
Christian

Hi there,
I have problems with understanding the logging procedure with chef.
I can log some information by using the following syntax:
log „foo" do
level :debug
end
Now I find in some cookbooks the following spelling:
Chef::Log.debug("Node has Chef Server Recipe?
#{node.recipe?("chef-server")}“)
This blog post is a pretty awesome and thorough description of how
chef-client has two stages: compile and converge:
http://erik.hollensbe.org/2013/03/16/the-chef-resource-run-queue/
Chef::Log.debug is a method call that writes a string to the logger,
which then writes it do some device (or not, depending on your log level,
etc.). The log resource puts an item in the resource_collection queue. In
the converge phase chef iterates over this queue, and will eventually run
this code
https://github.com/opscode/chef/blob/master/lib/chef/provider/log.rb
which you can see is more or less the same as Chef::Log.debug(). So the
primary difference is the timing.
What does Chef::Log.debug exactly do?
I do not get any output if i run the chef-client in normal or in debug
mode. What is the STDOUT from Chef::Log?
Did you configure chef to log to a file? Check your client.rb.
By the way, I am not really sure what Chef:: represents. Where can I
find the class or module Chef?
In some scripts I the other references like Chef::Client::SANE_PATHS.
Where can I find the content of such references?
Sorry if the questions are a litte bit stupid, but I am right new in
writing Code.
One easy way to spelunk the code is to clone the git repo from here:
GitHub - chef/chef: Chef Infra, a powerful automation platform that transforms infrastructure into code automating how infrastructure is configured, deployed and managed across any environment, at any scale and use git grep to search the codebase.
Thank you very much,
Christian
