Currently, PuppetDB's primary use is enabling advanced Puppet features. As use becomes more widespread, we expect additional applications to be built on PuppetDB.
If you wish to build applications on PuppetDB, see the navigation sidebar for links to the API specifications.
Checking node status
The PuppetDB plugins installed on your Puppet Server(s) include a
status action for the
node face. On your Puppet Server, run:
$ sudo puppet node status <NODE>
<NODE> is the name of the node you wish to investigate. This will tell you whether the node is active, when its last catalog was submitted, and when its last facts were submitted.
Using exported resources
PuppetDB lets you use exported resources, which allows your nodes to publish information for use by other nodes.
