I can't get a custom fact to work in Windows

[Dan McManus]

Hello all!

I am using open source puppet 3.0.1 on both the client and master. The issue I am having is that I cannot get a simple custom fact to be recognized in my manifest. Hopefully I am missing something. 

I am trying to have a custom fact that will tell me whether the nsclient++ directory exists or not.

Here's the custom fact, which is located at /etc/puppet/environments/windows/modules/nscp-test/lib/facter

Facter.add(:nsclient) do

setcode do

if File.exists?("c:/program files/nsclient++")

  puts ''nsclient installed'

else

  puts 'no such directory'

end

end

end

my init.pp is dead simple:

class nscp-test {

        notify{$nsclient :}

}

Here's what happens when I run puppet agent --test on the client (windows 2003):

C:\Documents and Settings\All Users\Application Data\PuppetLabs\puppet\var\lib\facter>puppet agent --test

Info: Retrieving plugin

Info: Loading facts in C:/Documents and Settings/All Users/Application Data/PuppetLabs/puppet/var/lib/facter/nsclient.rb

no such directory

no such directory

Info: Caching catalog for <snipped>

Info: Applying configuration version '1360274145'

Notice: undef

Notice: /Stage[main]/Nscp-test/Notify[undef]/message: defined 'message' as 'undef'

Notice: Finished catalog run in 0.42 seconds

from the command line,  facter --puppet nsclient works just fine.

So am I missing something dead simple, or what? This is my first time doing custom facts.

Thanks,

Dan

`puts` sends the string to stdout, you want to return the string. Ruby will implicitly return the last statement in a block. Which is how the examples in http://docs.puppetlabs.com/guides/custom_facts.html  works.

HTH,

Hah, yet, just removing the "puts" worked. Many thanks.

Note that you can also use Puppet.notice to help debug and such.
