RFacter is a (highly) experimental fork of Facter 2.x that executes facts defined in Ruby against remote systems over transports such as SSH and WinRM.

Run the rfacter binary on the command and pass it a list of nodes to inspect:

rfacter -n localhost -n some.remote.host \
  -n winrm://Administrator:password@some.windows.box

Special characters in passwords should be percent-encoded. I.e. V@grant! would become V%40grant%21.

See examples/fact_lookup.rb for an example of using RFacter as a library.

Currently, custom facts can only be added by setting the RFACTERLIB environment variable to a directories containing Ruby files:

export RFACTERLIB=${HOME}/some_facts:/var/lib/rfacter/my_facts

The directories should contain Ruby files with names matching the fact being defined. For example, the RFacter loader will expect my_fact to be defined in a file named my_fact.rb somewhere on the RFACTERLIB path. Custom facts can make use of the Facter 3 Ruby DSL:

Additional methods of configuring the loader will be added in a future release.
