net.sf.ehcache.Ehcache cache)
Ehcache instance with get and put timers
and a set of gauges for Ehcache's built-in statistics:
hits |
The number of times a requested item was found in the cache. |
in-memory-hits |
Number of times a requested item was found in the memory store. |
off-heap-hits |
Number of times a requested item was found in the off-heap store. |
on-disk-hits |
Number of times a requested item was found in the disk store. |
misses |
Number of times a requested item was not found in the cache. |
in-memory-misses |
Number of times a requested item was not found in the memory store. |
off-heap-misses |
Number of times a requested item was not found in the off-heap store. |
on-disk-misses |
Number of times a requested item was not found in the disk store. |
objects |
Number of elements stored in the cache. |
in-memory-objects |
Number of objects in the memory store. |
off-heap-objects |
Number of objects in the off-heap store. |
on-disk-objects |
Number of objects in the disk store. |
mean-get-time |
The average get time. Because ehcache support JDK1.4.2, each
get time uses System.currentTimeMillis(), rather than
nanoseconds. The accuracy is thus limited. |
mean-search-time |
The average execution time (in milliseconds) within the last sample period. |
eviction-count |
The number of cache evictions, since the cache was created, or statistics were cleared. |
searches-per-second |
The number of search executions that have completed in the last second. |
accuracy |
A human readable description of the accuracy setting. One of "None", "Best Effort" or "Guaranteed". |
N.B.: This enables Ehcache's sampling statistics with an accuracy level of "none."
