Hi,

I am using this chef cookbook to create a client ([https://github.com/sensu/sensu-chef](https://github.com/sensu/sensu-chef))

I literally copy and paste this into my cookbook:

```auto
sensu_client node.name do
  address node.ipaddress
subscriptions node.roles + ["all"]
additional(:cluster => node.cluster)
end

```

And it throw an exception at the ‘addtitonal’ line

```
   Relevant File Content:

You’re trying to use a Chef attribute “node.cluster” for a Sensu client definition attribute value. You have not defined that Chef attribute anywhere (in any cookbook attribute file or recipes).

Thanks for the answer.

Sorry, for me sometimes it is hard to tell if a problem lies with chef or sensu cookbook

Cheers, Tony
