The event inspector reports on data from which storage?

The correct answer is the storage from PuppetDB. PuppetDB serves as a central data storage for Puppet; it collects and stores data about nodes, resources, facts, and reports. The event inspector uses data stored in PuppetDB to provide insights and detailed reports about events, including the status of resources, changes that occurred, and any failures that were reported during Puppet runs. This enables users to easily track changes and manage resources effectively.

Furthermore, other storage options like the Puppet master might serve as a controller of configurations but do not retain the extensive historical data about resource states and events. Local caches on agent nodes typically contain temporary data to aid in performance and do not hold comprehensive logs for reporting. Agent nodes themselves manage their configurations and report back to the Puppet master but do not serve as a central repository for event data. Therefore, PuppetDB is the primary resource for the event inspector to gather and analyze event data.
