How to write/echo a log message when some event occurs using puppet?

Question

For example, if I want print "Reboot required!" when the file /var/run/reboot-required exists, how could I declare this in puppet?

I learned about alert(), warning() and the notify type, but I don't know how to trigger they only when some file exists.

You can write a Facter to check if the file exists :

/etc/puppet/modules/mymodulename/lib/facter/reboot_require.rb

Facter.add("reboot_required") do
        setcode do
                File.exist?("/var/run/reboot-required")
        end
end

Then in your manifests, call the fact,

if ($::reboot_required == 'true') {
    notify {"Reboot Required":}
}

Actually it is not working for me... it is always echoing "Reboot Required, even when the file is not there. What could be happening?

see my edit. I have added true to the if condition. That might fix it.

That is it! Thanks! :-) Just learned that puppet facts are always strings, that is so bad..
