Ohai is a tool that is used to detect attributes on a node, and then provide these attributes to the chef-client at the start of every chef-client run. Ohai is required by the chef-client and must be present on a node. (Ohai is installed on a node as part of the chef-client install process.)

The types of attributes Ohai collects include (but are not limited to):
o Platform details
o Network usage
o Memory usage
o Processor usage
o Kernel data
o Host names
o Fully qualified domain names
o Other configuration details

Attributes that are collected by Ohai are automatic attributes, in that these attributes are used by the chef-client to ensure that these attributes remain unchanged after the chef-client is done configuring the node.

ohai is the command-line interface for Ohai, a tool that is used to detect attributes on a node, and then provide these attributes to the chef-client at the start of every chef-client run.
