Cheers, --Amos Hi Amos, With PuppetDB you can query[1] for the most recent catalog of a given node which will list all of the classes used. You could the use the process of elimination to see what classes you had in your modulepath that are not showing up in your catalogs.

[Puppet Users] Is there a way to find unused puppet code (2.7)?
Hello, Is there a way to systematically find all modules we have which aren't used? Two reasons for this question: 1. We use librarian-puppet to manage external modules and would like to find which of them can we remove. 2. We did some major refactoring over the years, in particular we moved from a mix of old distribution to a single Ubuntu LTS version, and there could be some of our own classes which aren't used. 3. If it's an automatic way, it will be great to run it as part of our Continuous Integration suite to find code which can be removed. So - is there such a thing?

Re: [Puppet Users] Is there a way to find unused puppet code (2.7)?
I was thinking about this too. If your servers checkin every 30 minutos you can do: find /path/to/modules -amin +30 I have not tried it yet,but I suppose it works Regards, El 09/02/2014 02:53, Amos Shapira amos.shap...@gmail.com escribió: Hello, Is there a way to systematically find all modules we have which aren't used?

Re: [Puppet Users] Is there a way to find unused puppet code (2.7)?
I don't think it'll work, even though my servers do check in every 30 minutes: 1. From what I understand, the puppet master caches the manifest and doesn't re-interpret it unless it changed. 2. I have atime disabled on my servers. It saves tons of disk IO and is even the default on our platform (Ubuntu 12.04 LTS). I have a gut feeling that once Puppet interprets the manifest, it holds a tree of objects somewhere were I can scan and look for mention of every class in my Puppet source. I just found /var/lib/puppet/state/state.yaml, which has an entry for resource, including classes. Perhaps that's the direction to go but I was wondering whether there is already a tool to do that.
