PuppetDB 4.3: Facts wire format, version 5

Included in Puppet Enterprise 2017.1. A newer version is available; see the version menu above for details.

Facts wire format: Version 5

Facts are represented as JSON. Unless otherwise noted, null is not allowed anywhere in the set of facts.

{"certname": <string>,
 "environment": <string>,
 "producer_timestamp": <datetime>,
 "producer": <string>,
 "values": {
     <string>: <any>,

The "certname" key is the certname the facts are associated with.

The "environment" key is the environment associated to the node when the facts were collected.

The "values" key points to a JSON Object that represents the set of facts. Each key is the fact name, and the value is the fact value.

The "producer_timestamp" key points to a timestamp reflecting the time of fact set submission from the master to PuppetDB.

The "producer" key is the certname of the Puppet master that sent the fact set to PuppetDB. This field may be null.

Fact names and values must be strings.


The entire fact set is expected to be valid JSON, which mandates UTF-8 encoding.
