Nagios Chef-Client Handler

This Chef-client handler is available as Ruby Gem on the handler generates and updates a file on the local file system of a host that contains information about the latest chef-client run. The accompanying Nagios check the age of the file and reads its content. based o this information it reports back to Nagios.

The Gem is tested on Linux (RHEL6 & Binary compatibles) & MS-Windows 2008R2 but its likely it will run without issues on other OSses

"chef_client": {
  "load_gems": {
