Hi guys, I have a resource file:

resource\_name :send\_email

property :text, String, default: 'Unknown’  
property :node\_name, String, default: 'Unknown’  
property :subject, String, default: ‘Chef run’

action :send do  
require 'net/smtp’  
def\_emails = data\_bag\_item(‘def\_settings’, ‘emails’)  
message = "From: #{def\_emails[‘from’]}\>\n"  
message \<\< "To: #{def\_emails[‘to’]}\n"  
message \<\< "Subject: #{subject}\n"  
message \<\< "Date: #{Time.now.rfc2822}\n\n"  
message \<\< "#{text}\n"  
Net::SMTP.start(‘mailhost’, 25) do |smtp|  
smtp.send\_message message, “#{def\_emails[‘from’]}”, "#{def\_emails[‘to’]}"  
end  
end

Is it possible to run this resource in

Chef.event\_handler do  
on :run\_failed do

end  
end

It fails when I ran it

I’m sorry, but the event handler will not execute chef resources. The best bet is to create a library helper that takes in three parameters (text, node name, and subject) and call that from within the :run\_failed do block.
