prometheus_exporters

Pretty straightforward cookbook to install and configure some node exporters for Prometheus installation.

I've decided I want them to be available via chef custom resources (who knows where I would like to invoke them from) and all in one place.

Yes, It's a bit messy, but works fine.

Help us to clean up a bit if you have some spare time.

P.S. It's an eary release so do not expect much for at least a few weeks. :)

Supports

Only Ubuntu 14 & 16 for now.
