What does a "change" event indicate regarding a Puppet resource type?

A "change" event in Puppet indicates that the property of a resource type was out-of-sync with the desired state defined in the Puppet manifests, and as a result, Puppet made changes to align the actual state with that desired state. This means that when a change event is reported, it signifies that the Puppet agent has detected discrepancies between the current system configuration and what has been declared in the configuration files, necessitating adjustments.

In practice, this allows system administrators to track which resources have been modified during a Puppet run, facilitating easier troubleshooting and validation of changes. By emitting a change event, Puppet effectively communicates that an action was taken to correct a configuration drift, ensuring systems are maintained in their intended state.
