The fact values page (also known as the facts page) can be accessed via The Monitor Menu:

Monitor > Facts

The fact values page lists any and all facts for all hosts using orcharhino’s configuration management to report such facts. (In particular, facts are a core mechanism of the Puppet configuration management tool).

In essence, facts are just preset variables collecting a large range of system information. (Examples include mount points, BIOS vendor, IP addresses, Ruby version, and many more). These variables can then be used as part of your configuration management.
