Collect CacheAdapter stats in Symfony Profiler

The Symfony community added a cache data collector and profiler page since the 3.3.0 release. Which is a very nice feature to debug cache hits and misses.

Tagged CacheAdapters

By default it only collects data from CacheAdapters tagged with cache.pool. These Symfony CacheAdapters are already tagged:

• cache.app
• cache.system
• cache.validator
• cache.serializer
• cache.annotations

Collect your own CacheAdapter stats

It’s easy to add your own CacheAdapter to collect stats in the Symfony Profiler. The following snippet adds a ApcuAdapter to the Symfony Profiler.
