The module "Cache inspector" is a module to watch whats going on in the drupal cache tables. It is the ultimate Drupal cache viewer. It uses the fancy krumo viewer to show the strings, arrays, object etc. which are stored in the cache tables. The module is extremely useful for developers who want to understand the drupal built in cache mechanism.
The cache inspector module needs the devel module to be installed.
How the module works
Go to the Cache inspector page, to see all unserialized cache values of all drupal cache tables. The path is admin/config/development/cache-inspector. Use the adminstration menu an click to Home » Configuration » Development » Cache inspector.
First the cache inspector unserializes the serialized data in each selected cache table. Then it prints out the unserialized data with the krumo php library.
