The event inspector reports on data from which storage?

The event inspector reports on data stored in PuppetDB, which is the correct answer. PuppetDB acts as a centralized data storage system for Puppet, collecting and storing various information like facts, catalogs, and event data. It serves as the backbone for reporting and querying across different Puppet environments, enabling the aggregation of data from multiple sources.

In this context, the event inspector allows users to query and visualize event data, which specifically resides within PuppetDB, making it an essential tool for tracking and managing the state of Puppet runs. By leveraging PuppetDB, users can analyze historical data, monitor ongoing events, and enhance their understanding of how Puppet configurations are applied across their infrastructure.

Other storage systems like the Puppet master and agent nodes focus on real-time configuration delivery and execution, while the local cache typically holds temporary data specific to an agent's operations. These options do not provide the comprehensive reporting capability that PuppetDB offers, thereby reinforcing PuppetDB as the proper storage for the event inspector's data.
