This module provides a logging mechanism for cache invalidation and cleaning events in Magento 2. It helps developers and administrators track when, how, and from where the cache is being flushed, which is invaluable for debugging complex caching issues, especially those related to Varnish and third-party integrations.
- Logs cache cleaning events to a dedicated database table.
- Records details like the invalidation type (tags or type list), specific cache tags, the area of the application that triggered the cleaning (admin, frontend, cron), and a timestamp.
- Specifically logs Varnish purge actions, which can be very numerous and performance-intensive.
- Provides an admin grid to view, filter, and search cache log entries.
- Allows for mass deletion of log entries from the admin grid.
- Module and logging functionality can be enabled or disabled via system configuration.
