[jlact]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 5.5.6
• Ruby: 2.4.1
• Distribution: Centos 7
• Module version: 6.0.0

How to reproduce (e.g Puppet code you use)

class profiles::core::metrics (
Stdlib::Absolutepath $grafana_data_dir   = '/data/grafana',
Hash $grafana_plugins                    = {},
) {
...
  class { 'grafana':
      cfg                      => $grafana_config,
      data_dir                 => $grafana_data_dir,
      plugins                  => $grafana_plugins,
      provisioning_datasources => $grafana_datasources,
  }
...
}

profiles::core::metrics::grafana_plugins:
  grafana-piechart-panel: {}

What are you seeing

Plugin resource gets created and put in default location of /var/lib/grafana/plugins

What behaviour did you expect instead

Plugin resource gets created and put in defined location of /data/grafana/plugins

Any additional information you'd like to impart

The directory of /data/grafana/plugins is created as expected, just not used when the plugin resources are created via the CLI.
