Is there a module for tracking changes to a Drupal site's configuration? I want to create a simple system for tracking changes to my Drupal configurations and knowing which modules are used by some configuration settings is crucial, but will be happy to use an existing one if it is good enough. Is there a module that implements this?
I think you are looking for Configuration Management module.




  The module knows where configuration was changed and allows users to
  either "activate" a configuration that was changed in the datastore,
  or "write" to datastore if a configuration was changed in the
  activestore. If you enable the diff module, you can see the what is in
  the activestore vs. datastore.


and I'm not using this module before.
