We are using the puppet built in mechanisms with Nagios and that
concatenated_file.pp for Munin, that puppetstoredconfigclean.rb script
works like a charm, but I'm still having difficulty purging the now
unmanaged elements. Puppet isn't removing any of the unmanaged files
from the filesystem so concatenated_file.pp is still including them.
@@file { "/etc/munin/puppet/${fqdn}":
ensure => present,
content => template("munin/node.erb"),
tag => 'munin',
}
File <<| tag == 'munin' |>>
concatenated_file { "/etc/munin/munin.conf":
dir => "/etc/munin/puppet",
header => "/etc/munin/munin.conf.header",
require => File["/etc/munin/puppet"],
}
Should I be explicitly purging directories that contain the managed
files, e.g. /etc/munin/puppet? And if so how?
Thanks
