[chef] Logging and references questions

[Christian Fröstl < >]

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")}“)

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?

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.

Thank you very much,

Christian
