We have been Puppet user for 10 years and we are users of https://github.com/camptocamp/prometheus-puppetdb-sd However, that file_sd implementation contains business logic and assumptions around e.g. the modules which you are using. This pull request adds a simple PuppetDB service discovery, which will enable more use cases than the upstream sd. Signed-off-by: Julien Pivotto <roidelapluie@inuits.eu>
