Puppet oddities

I just noticed some strange Puppet behaviour. Take a look at this:

class monitoring {
  define nrpe_command (
    $ensure               = present,
    $command,
    $target               = "/etc/nagios/nrpe.d/$title.cfg"
  ) {
    file { $target :
      ensure            => file,
      owner             => root,
      group             => root,
      mode              => 0755,
      content           => "command[$title]=$command\n",
    }
  }
}
class puppet {
  monitoring::nrpe_command {"restart_puppet":
    command => "/etc/init.d/puppet restart"
  }
}

This is the resulting I’ve got:

testhost:/etc/nagios/nrpe.d# ls
puppet.cfg
testhost:/etc/nagios/nrpe.d# cat puppet.cfg
command[restart_puppet]=/usr/local/bin/restart_puppet_safely.sh
testhost:/etc/nagios/nrpe.d#

Somehow, puppet eats everything until the last underscore in the $title variable when using it in the file title, but not when using the variable as content for that file.

Any ideas?

  1. Mattias says:

    Have you tried correctly namespacing everything and perhaps replacing $title with $name?

    So the definition could be like “$target = “/etc/nagios/nrpe.d/$::name.cfg” “

  2. Actually, I just tried your suggestion, but that didn’t work out. Maybe I should add that this is puppet 0.25.4. Ancient, I know, but no explanation why it should behave like this.

  3. TomDV says:

    Have you tried escaping your variables?

    $target = “/etc/nagios/nrpe.d/${title}.cfg”
    content => “command[${title}]=${command}\n”,

  4. Issue remains the same :-(
