total_item_count - total number of elements that are currently in the session cache
is_local_cache - true is the cache metadata is for a local cache instance, false if the metadata is for the global cache
total_hit_count - number of times the data has been served from the cache
total_miss_count - number of times the data has not been found in the cache
scache_entries - an array that contains the information about all the cached items:
- key_name - name of the key which is used to store the data
- value_type - type of value stored by the key
- use_time - time in seconds since the file has been accessed in the opcode cache
- last_check - time in seconds since the file has been checked for modifications
- ttl_seconds - time remaining for the data to live in the cache, 0 meaning infinite
- age_seconds - time elapsed from the time data has been added in the cache
- hitcount - number of times data has been served from the cache
