Can I write a custom fact and see its value returned in the Admin Console?  Or does it only allow for the execution of Puppet Code based on conditionals and criteria meeting expectations?

If the answer is yes to the first question, can I simply write the Custom Fact, without necessarily making any changes to a Puppet Agent Node; so that I can assess certain details about my network that aren't native Puppet Facts?

My employer is creating systems, and we are "stamping" them with a text file under /etc/ and we want to be able to grab the content of the file WE CREATE under /etc to determine if machine A, B....Z are part of Baseline1 or Baseline2; for example.

Thanks in advance,

If you deploy the custom fact, the agent would need to perform a single run and then send the report to puppetdb. Afterward, it would be visible in the admin console (assuming you mean PE console here) in all the usual places, such as in the node details and filtering by fact valued.

The runs don't need to change anything, but they do need to complete and send the report; if this doesn't happen every 14 days by default, it will get purged from puppetdb and of course no longer show up.

Hi Rob, thanks.

A single run?  Runs don't need to change anything, but they do need to complete and send the report?  How do I accomplish that?

Are you saying an empty class would do?

Yeah, a 'profile::base' that does nothing or just updates the motd if you want a very simple manifest would do just fine.

rnelson, I managed to create 2 .rb files and several Custom Facts (I don't know the more succinct term).

It worked out awesomely!  Thank you again.
