Released a Puppet module for Prometheus.
It is quite crude, but is easy to use, maintain and extend.
Deploy the server.pp on the prometheus server and the various exporters on the clients, these are collected with PuppetDB on the Prometheus server.
The motivation behind creating this module was that the (great) and official module had several dependencies that could not be fulfilled. This module does not have any deps other than stdlib.
The module can be found at https://git.frank2.net/frank/t7d_prometheus
