Puppet users - Nov 2013 - PuppetDB - notify Puppetmaster

Hi guys,

I want the Puppetmaster to be notified if an agent has put new data into 
the PuppetDB, which is installed on the puppetmaster. After each incoming 
new data for PuppetDB I want to execute a command on the Puppetmaster.

How can I do that?

There is currently no ping-back or event subscription mechanism in PuppetDB to
allow you to register a callback that gets invoked upon changes in the
underlying data. This would not be hard to add (especially as there''s
already a MQ active inside of PuppetDB), but it doesn''t exist yet.
Please file a feature request! :)

In the meantime, you could implement this via polling the "nodes"
endpoint:

http://docs.puppetlabs.com/puppetdb/1.5/api/query/v3/nodes.html

That will return to you metadata about all your active nodes, such as when they
last received a catalog or new facts or a new report. You could use that to
determine when to invoke an external command or not.

You could also use exported resources, and simply do this on all clients:
@@exec { "/bin/command-to-run-on-mater": tag => "master"
}

and then collect on the master:

Exec <<| tag = ''master'' |>>
