/fact-names endpoint can be used to retrieve all known fact names.
This will return an alphabetical list of all known fact names, including those which are known only for deactivated nodes.
This endpoint does not use any URL parameters or query strings.
The response will be in
application/json, and will contain an alphabetical
JSON array containing fact names. Each fact name will appear only once,
regardless of how many nodes have that fact.
[<fact>, <fact>, ..., <fact>, <fact>]
curl -X GET http://localhost:8080/v3/fact-names ["kernel", "operatingsystem", "osfamily", "uptime"]
This query endpoint supports paged results via the common PuppetDB paging URL parameters. For more information, please see the documentation on paging.
