Configuration Inspector

Configuration inspector uses the core built-in configuration system as well as schema system to let you inspect configuration values and the use of schemas on top of them. This makes it possible to have a developer focused overview of all your configuration values and do various testing and verification tasks on your configuration schemas. The module also checks whether your configuration is valid and allows you to inspect which plugins are used to validate it.

The module provides a menu item under: Reports > Configuration inspector that lets you inspect configuration, comparing raw configuration data with schemas; looking at configuration through the schema in a table of summary, in a tree view or in a form.
