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[x].name.to_s + " " + cookbooks[x].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
