Error installing on CentOS

[LordBrain]

Trying to install this module with foreman/puppet I get the following error:

err: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed to parse template ganglia/gmetad.conf.el6.erb:
Filepath: /etc/puppet/environments/unstable/modules/ganglia/templates/gmetad.conf.el6.erb
Line: 39
Detail: undefined method `each' for nil:NilClass
at /etc/puppet/environments/unstable/modules/ganglia/manifests/gmetad/config.pp:21 on node host1.example.com
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run

Is my system missing something?

This is almost certainly the template failing to handle a nil/undef value. Could you share the manifest snippet in which your declaring ganglia::gmetad?

[LordBrain]

Sorry, I am very new to puppet. Are you referring to something within foreman or the gmetad.pp?

[jhoblitt]

PR #14 added parameter validation that prevent invalid data from being passed into the ganglia::gmetad clusters parameter that could cause the sort of template error you reported. Please reopen this ticket if the error can be reproduced from the current master branch.
