Questions tagged [facter]

Facter is an independent, cross-platform Ruby library bundled with Puppet, designed to gather basic node information about the hardware and operating system

Developed by Puppet Labs to help with automated system configuration management. A puppet manifest declares the required state of the machine. Facter retrieves the current state, so that Puppet can work out what changes need to be made, and how.

The Facter gem can be used by any Ruby system, without the rest of Puppet.
