Puppet Class: prometheus::install

Defined in:
manifests/install.pp

Summary

Install prometheus

Overview

Install prometheus via different methods with parameters from init

Currently only the install from url is implemented, when Prometheus will deliver packages for some Linux distros I will implement the package install method as well

The package method needs specific yum or apt repo settings which are not made yet by the module
