Cache Collector

Captures cache operations (get, set, delete) with hit/miss rates, timing, and per-pool breakdowns.

What It Captures

Field	Description
pool	Cache pool name (e.g., default, sessions)
operation	Operation type (get, set, delete, has, clear)
key	Cache key
hit	Whether the operation was a cache hit
duration	Operation execution time in seconds
value	Cached value (for get/set operations)

How It Works

Framework adapters intercept PSR-16 CacheInterfacePsr\SimpleCache\CacheInterfacePSR-16 Simple Cache Interface. Defines basic cache operations.PSR-16 · interface operations through the CacheInterfaceProxy decorator. Every get(), set(), delete(), has(), and clear() call is automatically captured.

Debug Panel

• Hit rate summary — total operations, hits, misses with percentage
• Per-pool breakdown — statistics grouped by cache pool when multiple pools are used
• Operation list — filterable list with operation type, key, hit/miss status, and timing
• Color coding — hits (green), misses (orange), deletes (yellow)
• Value preview — expandable cached values for get/set operations
