Regarding where to place custom notification handler

I think that keep it as special cookbook recipe is much better option
As we do´nt need to update individual client config when we change the 
notification handler or
upgrade chef-client


This is example of my chef_run_notify cookbook

#file cookbooks/chef_run_notify/recipes/default.rb
 
require 'net/smtp'

class CustomLogHandler < Chef::Handler
  # Define a report method to run your notification logic
  def report
    Chef::Log.info("#{self.class.name} started for #{node.name}")
    Chef::Log.info("#{self.class.name} Updated #{updated_resources.size} of 
#{all_resources.size} resources")

    if updated_resources.size > 0 or failed?
      message = "From: 

 "
      message << "To: 

 "
      if failed?
         message << "Subject: Chef Run on #{node.name} in #{elapsed_time} 
seconds FAILED\n"
      else
         message << "Subject: Chef Run on #{node.name} in #{elapsed_time} 
seconds SUCCEED\n"
      end
      message << "Date: #{Time.now.rfc2822}\n\n"

      if success?
        message << "Updated\n #{updated_resources.map {|r| r.name}.join("\n 
")}"
      else
        message << "#{run_status.formatted_exception}\n"
        message << Array(backtrace).join("\n")
      end

      node[:mailhost] ||= Mash.new
      node[:mailhost][:host] ||= 'mailhost.mydomain.com'
      node[:mailhost][:port] ||= '25'

      Chef::Log.info("#{self.class.name} notify by e-mail via 
#{node[:mailhost][:host]}:#{node[:mailhost][:port]}")

      Net::SMTP.start(node[:mailhost][:host], node[:mailhost][:port].to_i) do 
|smtp|
        smtp.send_message message, 
'
 ',
 
'
 '
      end
    end
    Chef::Log.info("#{self.class.name} completed")
  end
end

Chef::Config.report_handlers << CustomLogHandler.new     # these fire at the 
end of a successful run
Chef::Config.exception_handlers << CustomLogHandler.new  # these fire at the 
end of a failed run
