Puppet and Puppet Enterprise Proxy Configuration

There are a few places you can configure proxies with Puppet. This doc will try and list each of the places that they can be configured, and which components will use it.

This is a work in progress and will no doubt change over time. Please add comments if you've got additional info, or found something incorrect.

Guide to Resetting a csync2 Cluster

Introduction

These are possible steps to reset a csync2 cluster that has been seriously fubared. This is an apocalyptic approach and should only be used when more surgical fixes (like correcting an individual conflict) aren't workable.

Use Cases

check_puppet_run_health

A Nagios check that connects to PuppetDB and determines the Puppet agent run health on a host.

Requires

PuppetDB
A puppetmaster configured to send reports to PuppetDB
