#I spent many hours today trying to grok Handlers in Chef, and get a functional email handler in place.
#This is a brain dump of my configuration in the hopes that others find it useful (and to remind myself).

#cd to your repo's cookbooks directory, download the chef_handler cookbook, and un-tarzip
knife cookbook site download chef_handler
tar -xvzf chef_handler.tgz

#create a send_email.rb handler in your default chef_hander handler directory with the below results
#replace EMAILADDRESS, DOMAIN, EMAILSERVER with values for your environment

#BACKSTORY:
#I wanted to get a way to quickly and centrally see how my Chef runs might be going.

#SUMMARY:
#1. I built a quick web service in PHP (details not pertinent here), that takes parameters node, status, and runlist, and saves the results to a database for reporting purposes
#2. I configured Chef to call my PHP web service on each successful and failed chef-client run using Chef.event_handler in my default.rb

#created a helper.rb at ~/POP/cookbooks/MyCookbook/libraries/helper.rb
